Abstract ：
Reducing the sulfur content in high-sulfur petroleum coke (HSPC) to below 3.0 % is a big challenge for refineries to meet environmental policy and legal requirements in China. The HSPC examined in this study has a high sulfur content of 7.13 %, with almost all of the sulfur existing in the form of thiophene compounds. The introduction of H2 and the addition of Na2CO3 both promote the sulfur release of HSPC at 800 degrees C. With a 50 % addition of Na2CO3 and the introduction of H2, 87.2 % of the sulfur is released from the HSPC. The details of sulfur distribution during the desulfurization reaction were determined to clarify the roles of H2 and Na2CO3. Thiophene is mainly transformed into gaseous and water-soluble sulfur compounds. The gaseous sulfur includes H2S, elemental sulfur, and sulfur-containing tar (Tar-S). The water-soluble sulfur compounds are primarily sulfides and sulfates adsorbed on the petroleum coke, which can be removed by water washing. The results show that H2 and the addition of Na2CO3 exhibit a synergistic effect on HSPC desulfurization. H2 promotes the hydrogenolysis of C-C and C-S bonds in benzothiophene to form H2S and Tar-S, while Na2CO3 acts as a captor of sulfurcontaining compounds. The findings of this work provide a foundation for the development of a cost-effective and highly efficient industrial desulfurization process.

Abstract ：
Developing high-performance Ca-based materials that can work for long-term heat transfer and storage in concentrated solar power plants is crucial to achieve the large-scale conversion of solar photon fluxes to dispatchable electricity. This work demonstrates that a series of Mn, Zr co-doped CaCO3 nanomaterials with the 3D ordered macroporous (3DOM) skeletons are successfully prepared by a novel strategy of templated metal salt co-precipitation. The characterization results indicate that a majority of Zr and Mn are atomically dispersed into the highly-crystallized CaCO3 framework, whereas a minor amount of Mn is present in the form of CaMnO3 nanoparticles (NPs). The optimal 3DOM material made by templating with PS microspheres with a diameter of approximate to 350 nm, 3DOM-Ca80Mn10Zr10, shows a solar light absorptance of approximate to 74.1% and an initial energy storage density of 1706.4 kJ kg(-1). Importantly, it gives an impressive energy storage density loss of < 6.0% and maintains above 1600 kJ kg(-1) after 125 cycles. The density functional theory calculations reveal that the co-doping of Mn and Zr into the CaO crystal lattice offers a strong affinity to [Ca4O4] clusters, as a result, the anti-sintering of CaO NPs is significantly enhanced under high temperature.

Abstract ：
The chemical enhancement of semiconductor-based surface-enhanced Raman scattering (SERS) substrates is an exciting hot topic. Herein, a simple hydrothermal method is developed to prepare molybdenum disulfide (MoS2), which can be easily exfoliated into monolayer nanosheets (MoS(2)NSs) by sonication, even in the absence of any surfactant. The obtained MoS(2)NSs contain two types of defects, namely, one caused by the incorporation of Mo atoms of high valence states and one caused by the incorporation of S-2(2-). The density of the two types of defects can be easily tuned by controlling the ratio of Na2S and Na2MoO4 in the raw materials. The unique properties and the clear surface make the obtained MoS(2)NSs ideal models to investigate the effect of defects on the SERS activity of MoS2. It is found that the SERS activity of the obtained MoS(2)NSs increases dramatically with the defects caused by Mo atoms of high valence states, while it first increases and then decreases with the increase of defects caused by S-2(2-). On the basis, MoS(2)NSs with high SERS activity and a low detection limit of 5.0 x 10(-9) mol/L toward crystal violet (CV) are obtained. Moreover, the mechanism of defects affecting the SERS activity of MoS(2)NSs is revealed. The defects on one hand provide a large amount of dangling bonds that can combine CV molecules to form MoS2NS-CV complex and on the other hand provide extensive induced local dipoles and enhance the overall SERS spectrum of CV.

Abstract ：
Aiming to improve the decay in thermochemical energy storage (TCES) performance of CaO-based looping materials with the number of carbonation/calcination cycles, a series of Y/Mg-codoped CaO-based materials were prepared by using the classical sol-gel method and citric acid as a carbon template to enhance the porosity and specific surface area. The structural characterizations showed that Y and Mg were presented in two forms. Part of Y/Mg was presented in the form of Y2O3 and MgO nanoparticles with an average size of 15 and 40 nm, respectively. These Y2O3 and MgO nanoparticles with high Tammann temperature and thermal conductivity were highly dispersed to retard the sintering and growth of CaO grains. The rest of Y and Mg were doped into the framework of the CaO lattice in atomic form by substituting Ca atoms. These Y and Mg created a large amount of the oxygen vacancies surrounding Ca atoms to facilitate the electron transfer from Ca2+ ions to dopants, which enhanced the CO2 capture capacity of CaO-based materials by improving the kinetics of the carbonation reaction. As a result, the optimal CaO-based composite denoted as Ca/Y5/Mg10 exhibited a high initial energy storage density of up to >2300 kJ/kg and held an excellent looping reaction stability after 25 carbonation/calcination cycles owing to the cooperation of Y with Mg additives. This work provided effective and economical CaO-based looping materials for application in thermochemical energy storage.

Abstract ：
We report a facile yet effective strategy to prepare hierarchical Beta zeolite with high molecular transport effectivity in catalysis. Alkaline etching involves preferential desilication from Beta framework and collapse of microporosity. The preferential desilication from outer rim of Beta stacking faults enlarged intercrystallite mesopores, while the collapse of microporosity created cylindroid-like intracrystalline mesopore. Part of Altet with lower stability was removed during alkaline etching, leading to a decrease in acid sites density. Alkaline etching of Beta zeolite with 0.2 mol/L NaOH solution greatly improved n -hexane isomerization activity over Ptbased catalysts. The maximum yield of isohexane and dibranched isomers increased by 6.2 % and 38.6 %, respectively. The enlargement of intercrystallite mesopores and the generation of intracrystalline mesopores of Beta zeolite lowered apparent activation energy of reaction. The apparent diffusivities measurements further revealed that Pt/Beta-0.2 M showed much lower transport limitation than Pt/Beta-parent. Our findings provide a promising catalyst for industrial alkane isomerization.

本发明公开了一种小晶粒SAPO‑11分子筛的快速制备方法，包括以下步骤：将水、磷源、铝源、模板剂搅拌均匀在一定温度下预晶化，结束后取出产物加入硅源和有机酸，再次搅拌均匀后进行水热晶化，晶化结束后离心得到固体产物，最后高温焙烧脱除模板剂即得到所述分子筛。水热晶化是目前合成SAPO‑11分子筛最常用的方法，但其存在反应周期长(≥24h)，生成的晶核表面吉布斯自由能过高，晶粒自聚倾向高，颗粒尺寸大、比表面积低的缺点，从而导致反应物及产物在催化剂上的扩散速率慢、裂化严重或选择性低。本发明通过在合成体系中加入有机酸的方式调控分子筛成核和生长策略，不仅可大幅度降低反应周期，且有效抑制分子筛晶粒尺寸。
