Abstract ：
A critical technological roadblock to the widespread adoption of proton-exchange membrane fuel cells is the development of highly active and durable platinum-based catalysts for accelerating the sluggish oxygen reduction reaction, which has largely relied on anecdotal discoveries so far. While the oxygen binding energy Delta E-O has been frequently used as a theoretical descriptor for predicting the activity, there is no known descriptor for predicting durability. Here we developed a binary experimental descriptor that captures both the strain and Pt transition metal coupling contributions through X-ray absorption spectroscopy and directly correlated the binary experimental descriptor with the calculated Delta E-O of the catalyst surface. This leads to an experimentally validated Sabatier plot to predict both the catalytic activity and stability for a wide range of Pt-alloy oxygen reduction reaction catalysts. Based on the binary experimental descriptor, we further designed an oxygen reduction reaction catalyst wherein high activity and stability are simultaneously achieved.

Abstract ：
In order to study the influence mechanism of heat treatment and heterostructures on the photoelectrochemical effect of WO3, monoclinic WO3 nanoflowers were synthesized by low-temperature solvothermal method. The active crystal fact, grain size and crystallinity of WO3 were controlled by heat treatment. Furthermore, WO3/CdS/alpha-S heterojunction was obtained by modified chemical bath deposition, and the concentration effect of its photoelectrochemical performance was studied. The results show that the (200) crystal plane with photoelectrochemical activity is the main exposed crystal plane of WO3, and the proportion of the exposed crystal plane increases with the heat treatment temperature increasing. The WO3 nanoflower treated at 350 degrees C showed the highest photoresponse current. By constructing WO3/CdS/alpha-S heterojunction, the material's absorption in the visible light region is enhanced, and the overall efficiency of photo-generated carrier separation is improved by sacrificing a small amount of carriers, which promotes the macroelectronic chemical effects of WO3.

Abstract ：
TiO2 nanocrystal (NC)-based photoreversible color switching (PCS) materials, which are capable of actively responding to external light, have significant potential for use in printable rewritable paper in the creation of sustainable technologies. Reductive TiO2 NCs with high hole-scavenging capabilities can be obtained by surface disorder or lattice distortion, but achieving an optimum balance between them is still a great challenge to enable simultaneous retention of the photoreduction performance and visible light catalytic ability of the TiO2 NCs. Here, we demonstrated solvent-controlled synthesis of interstitial Sn2+-doped TiO2 NCs and investigated the effects of solvent-induced surface disorder and doping-induced lattice distortion on the PCS properties of the TiO2 NCs. The midgap state produced by surface disorder combines with the energy level produced by the interstitial Sn2+ dopants in TiO2 NCs to become the main center for photogenerated electron transfer. Thus, efficient PCS was achieved, with the number of switching cycles greatly increased. The ethylene glycol-synthesized TiO2 NCs with a Sn2+-doping concentration of ca. 3% are the most favorable catalyst for achieving PCS performance. The process of PCS can be repeated 48 times without any rest. The results of this work suggest an approach to the design and preparation of PCS materials that exhibit excellent scalability and outstanding reversible performance by using colloidal NCs with optimized surface composition, lattice structure, and particle size as key-functional photocatalysts.

Abstract ：
Because the advantages of non-direct contact, remote control, high efficiency and fastness, light-driven reversible color switching materials (LDRCSMs) have important applications in information storage, display devices, sensors, and other fields. The combination of inorganic materials and organic materials to achieve synergies is one of the research hotspots of new LDRCSMs. A one-step liquid-phase synthesis method was used to prepare Mg-doped TiO2 nanocrystals (Mg-TiO2 NCs) with a particle size of similar to 5 nm. The reversible light-responsive color switching of methylene blue (MB) by using Mg-TiO2 NCs was investigated. The results show that Mg2+ doping generates impurity levels in the TiO2 lattice, effectively inhibiting the recombination of photogenerated carriers and increasing the activity of TiO2 photooxidation-reduced MB. On the other hand, Mg2+ doping can decrease the absorption wavelength of TiO2 NCs, which effectively represses the partial reduction of MB to reduced LMB under visible light irradiation, leading to a higher recoloration rate. Such LDRCSMs based on alkali metal-doped TiO2 NCs may have potential application in many optoelectronic device fields.

Abstract ：
Current methods that utilize Fenton-like reagents to remove persistent organic pollutants suffer from several limitations, i.e., the reagents may release metal ions into the sludge and cause secondary pollution, the reagents are easily inactivated after use, and the use of additives (e.g., 2KHSO(5)center dot KHSO4 center dot K2SO4, Na2S2O8 and H2O2) can be costly but cannot be avoided. In this work, through a one-pot reaction, we prepared surfactant-free porous nano-Mn3O4 as an efficient Fenton-like reagent. Without the addition of external H2O2, it could remove 86.8% and 96.9% of the phenol from an aqueous solution within 1 and 5 min, respectively, and thus outperformed many other reported reagents. The underlying mechanism for the removal of organic pollutants by this Mn3O4 reagent was examined. It was found that the low-valence Mn in Mn3O4 reacted with the dissolved O-2 to generate H2O2, and the H2O2 in turn created hydroxyl radicals (HO center dot) to degrade organic pollutants. The Mn3O4 was also annealed to generate porous nano-Mn2O3, and a comparison of the performance of Mn3O4 and Mn2O3 in removing organic pollutants revealed that low-valence Mn in the oxides played a critical role in scavenging the pollutants. Note that this novel nano-Mn3O4 could remove pollutants without the addition of external H2O2, and it could be easily reactivated after use through reduction by NaBH4 and thus be recycled. The Mn3O4 can also be successfully applied to complex polluted water containing a mixture of phenolics. These findings pave the way for developing other efficient and environmentally friendly Fenton-like reagents for removing organic pollutants in wastewater.
