Abstract ：
Polyethylene terephthalate (PET) is a polymer synthesized via the dehydration and condensation reaction between ethylene glycol and terephthalic acid. PET has emerged as one of the most extensively employed plastic materials due to its exceptional plasticity and durability. Nevertheless, PET has a complex structure and is extremely difficult to degrade in nature, causing severe pollution to the global ecological environment and posing a threat to human health. Currently, the methods for PET processing mainly include physical, chemical, and biological methods. Biological enzyme degradation is considered the most promising PET degradation method. In recent years, an increasing number of enzymes that can degrade PET have been identified, and they primarily target the ester bond of PET. This review comprehensively introduced the latest research progress in PET enzymatic degradation from the aspects of PET-degrading enzymes, PET biodegradation pathways, the catalytic mechanism of PET-degrading enzymes, and biotechnological strategies for enhancing PET-degrading enzymes. On this basis, the current challenges within the enzymatic PET degradation process were summarized, and the directions that need to be worked on in the future were pointed out. This review provides a reference and basis for the subsequent effective research on PET biodegradation.

Abstract ：
The xZrO2/TiO2-PMo(y) catalysts were synthesized using a conventional impregnation method with TiO2 as the support. By simply adjusting the loading amount of Zr species and the addition of phosphomolybdic acid, the acid and basic properties of the catalysts were rationally modulated. The synthesized 30%ZrO2/TiO2-PMo(6) catalyst exhibited excellent Meerwein-Ponndorf-Verley (MPV) reduction performance, achieving a 90.8% yield of γ-valerolactone (GVL) from levulinic acid (LA) at 180 °C within 3 h. The total acidity, Lewis and Brønsted acid sites, and basic sites of the xZrO2/TiO2-PMo(y) catalysts were characterized and their effects on the MPV reduction of LA to GVL were detailed discussion. The deactivation of the 30%ZrO2/TiO2-PMo(6) catalyst was mainly due to the carbon deposition instead of leaching, and the catalytic performance could be restored through an effective regeneration method. Additionally, the 30%ZrO2/TiO2-PMo(6) catalyst demonstrated superior universality in the MPV reduction of methyl levulinate (ML), ethyl levulinate (EL), and butyl levulinate (BL) to GVL, with yields of 85.3%, 84.2%, and 83.7% for ML, EL, and BL, respectively. This study presents a sustainable method for the MPV reduction of LA to GVL and provides a potentially valuable reference for other reactions that involve the synergistic catalysis of Lewis and Brønsted sites along with basic sites. © 2024 Elsevier Ltd

Abstract ：
A series of zirconium phosphate (ZrP) loaded H -beta -25 zeolite (i.e., ZrP@HB) multifunctional composite catalysts were synthesized by a simple co -precipitation method, and the one -pot upgrading for the transfer hydrogenation of furfural to gamma -valerolactone (GVL) was systematically investigated through various characterizations and catalytic evaluation experiments. Comparative characterization analysis of the ZrP@HB-X (Y) catalysts showed that the ZrP@HB-4(4) catalyst has uniform distribution of elements, exhibiting a large specific surface area and hierarchical mesoporous/microporous structure. Fourier transform infrared spectroscopy of pyridine (Py-FTIR) and NH 3 temperature -programmed desorption characterizations indicated the presence of Lewis and Br & oslash; nsted acid sites, as well as weak, moderate, and strong acid sites in the ZrP@HB-4(4) catalyst. It was confirmed by X-ray photoelectron spectroscopy and FTIR that the main reason for Lewis and Br & oslash; nsted acid sites formation is the presence of P-O-Zr, P -O -H, and HB zeolite on the ZrP@HB-4(4) catalyst. The HB zeolite as well as Zr and P ratio, can be easily adjusted to efficiently regulate the acidity strength and Lewis and Br & oslash; nsted acid sites of the ZrP@HB-X(Y) catalysts. The catalytic experiments demonstrated that the physicochemical properties of the ZrP@HB-4(4) catalyst mentioned above significantly enhance the GVL production. Notably, Lewis and Br & oslash; nsted acid sites as well as transition metal sites of Zr in the ZrP@HB-4(4) catalyst were identified as the main factors that enhance the yield of the target product. By optimizing the reaction conditions, the yield of GVL could be as high as 88.16%. Reusability experiments demonstrate that the ZrP@HB-4(4) catalyst possesses excellent stability. Using levulinic acid as the substrate, the yield of GVL reached 93.92%, suggesting its potential versatility.

Abstract ：
The conversion of biomass-derived substrates to 1,2-butanediol (1,2-BDO) is an important process for biomass valorization, but the low yield of 1,2-BDO and unclear reaction pathways and catalytic mechanisms hinder its development. To address these challenges, this review proposes that generating C4 intermediates and transforming them to 1,2-BDO are two critical procedures for enhancing the yield of the target product. It is suggested that the specific functional catalysts should be designed to facilitate these two steps and inhibit side reactions, thus achieving progress in yield. Considering the possible presence of multiple intermediates in the reaction process, innovative approaches and rational detection methods are put forward to reveal the pathways of 1,2BDO production. Specifically, potential reaction pathways are proposed, stepwise advancement and feedback should be guided to compare the product distributions and model molecules during the conversion process, and combined with specific detection methods such as isotopic exchange method and situ on-line Fourier transform infrared spectroscopy to clarify the pathways. According to the reaction characteristics, adjusting the Bronsted to Lewis acid ratios, base strength, oxidation state, and combined with theoretical calculations to reveal the mechanisms that promote the formation of the target product and inhibit side reactions. Research breakthroughs in transforming biomass-derived substrates to 1,2-BDO with these approaches are anticipated.

Abstract ：
The conversion of hemicellulosic biomass to sugar alcohols commonly applies homogeneous acids and noble metals as catalysts, which is neither economical nor environmentally friendly. In order to overcome the deficiencies of the reports, a series of non-precious catalysts were synthesized through the co-precipitation method and incipient wetness impregnation (IWI) method in converting hemicellulosic biomass, i.e., hemicellulose and xylose into sugar alcohols (i.e., xylitol and arabitol). Reaction experiments showed that the Ni8.98Fe1 @ 1.54SiO(2) catalyst prepared by the IWI method has excellent catalytic performance for converting xylose to sugar alcohols in the neutral aqueous solution, and can be applied to the direct conversion of hemicellulose as well. Specifically, the optimum yield of xylitol and arabitol could obtain 99.48 mol% and 26.01 mol% for xylose as the substrate and 88.16 mol% and 20.55 mol% for hemicellulose as the substrate, respectively. Characterization techniques such as X-ray diffraction (XRD), N-2 adsorption-desorption isotherm, transmission electron microscopy (TEM), scanning electron microscope (SEM), H-2 temperature-programmed reduction (H-2-TPR), NH3 temperature-programmed desorption (NH3-TPD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy of pyridine (Py-FTIR), and SQUID vibrating sample magnetometry (SQUID -VSM) were performed to study physicochemical properties of the catalyst. N-2 adsorption-desorption isotherm and NH3-TPD characterizations indicated that the catalyst with mesoporous properties and proper acidic sites is vital for hydrolyzing hemicellulose to pentose (i.e., xylose and arabinose). TEM, H-2-TPR, and XPS techniques revealed that the (111) plane of metallic Ni is the main active phase for the hydrogenation of pentose into sugar alcohols, and Fe2+ and Fe3+ species act as effective promoters to enhance the pentose hydrogenation. Py-FTIR characterization and reaction conditions indicated that the appropriate ratio of Bronsted to Lewis acidic sites could facilitate the conversion of xylose to arabitol. The reaction mechanisms for converting hemicellulosic biomass to sugar alcohols were proposed based on the systematic study of reaction conditions and characterizations. N-2 adsorption-desorption, H-2-TPR, and XPS indicated that the catalyst with strong metal-support interaction, large specific surface area and pore volume could be beneficial for catalytic stability, which is verified in leaching and reusability tests. The catalyst has superparamagnetic, which can be quickly separated from the reaction system under the external magnetic field, facilitating the recovery and utilization of the catalyst.

Abstract ：
In this study, the acid-base bifunctional magnetic ZrMg@Fe3O4 metallic oxide catalysts with remarkable structural properties were synthesized by the co-precipitation method for the catalytic transfer hydrogenation (CTH) of furfural (FF), ethyl levulinate (EL), and 5-methylfurfural (5-MF) to furfuryl alcohol (FFA), gamma-valerolactone (GVL), and 5-methyl-2-furanmethanol (5-MFA). Characterization results indicated that the ZrMg@Fe3O4 (7: 1:1) catalyst possesses a substantial pore volume, large specific surface area, and mesoporous properties, which play an important role in improving catalytic activity. The leaching experiment indicated that the catalyst was not prone to leaching, proving its structural stability. The yield of FFA, GVL, and 5-MFA could be as high as 92.50%, 95.00%, and 53.95% by optimization experiments. The Py-FTIR, CO2-TPD, and poisoning experiments showed that Lewis acid-base sites significantly impact the catalytic activity. The catalyst can be readily isolated and retrieved from the liquid reaction mixture by applying the external magnetic field. The reaction mechanism and catalytic stability were also conducted by systematically studying the reaction experiments and physicochemical properties of the catalyst.
