Summary: A simple and low-cost Ru/activated carbon (AC) catalyst was developed for the hydrogenation of dimethyl oxalate (DMO) to methyl glycolate (MG) under mild conditions. The Ru/AC catalyst demonstrated superior catalytic performance, which could be attributed to its high dispersion of Ru, small particle size, weak surface acidity, and electron-deficient state of Ru species.

Summary: The hydrogenation of dimethyl oxalate to produce ethanol is a research topic of great interest due to its environmentally friendly nature. However, the yield of ethanol using Cu-based catalysts remains a challenge. In this study, a molybdenum-doped Cu catalyst was synthesized and demonstrated to be a robust catalyst with a high ethanol yield. The addition of Mo increased the amount of surface Cu+ species and enhanced the surface acidity, resulting in a high ethanol selectivity.

Summary: Efficient electrical energy conversion can be achieved by refining the size of nonprecious metal-based catalysts and confining them in multiheteroatom-doped hierarchical porous carbon. The ultrasmall Mo2C nanocrystals (us-Mo2C) embedded in N and S double-doped hierarchical porous carbon show improved hydrogen production efficiency due to synergistic effects of size-controlled Mo2C, multidoped heteroatoms, and multiscale assembly structures. This study paves the way for constructing ultrafine nanocrystals and high-value conversion of waste biomass.

Summary: The present energy dilemma has prompted researchers to search for new renewable energy sources with minimal CO2 emissions. Producing biofuels and platform chemicals from sustainable biomass resources is of great significance, but developing high-efficiency catalysts remains a key scientific challenge. Transition metal carbides, particularly molybdenum carbide, have shown promising performance in biomass conversion. Recent developments in preparing molybdenum carbide as a catalyst in biomass to fuel conversion, focusing on preparation methods, structure-dependent effects, and electronic modulation, are summarized in this review. The controllable selective cleavage of C-C, C-O, and C-H bonds over modified molybdenum carbides is highlighted. The review also presents possible deactivation mechanisms of molybdenum carbide, providing systematic and fundamental information for further design and development in biomass conversion.

Summary: La2O3-MgO composites were successfully fabricated by spray pyrolysis-post calcination method with the addition of citric acid. The addition of citric acid and La component played a key role in the formation of composite oxides with abundant pores and large surface area. The La2O3-MgO composites showed excellent CO2 adsorption performance due to the promoting effect of La(2)O(3) addition on microstructure and physicochemical features.

Summary: Salicylic acid (SA) was used as a complex-combustion aid to prepare MgO-based adsorbents (MBA) for CO2 capture. The research investigated the effects of different La doping content, calcination time and temperature, and the mole ratio of SA to metal nitrates on the physico-chemical properties and CO2 adsorption capacity of the MBA. The MBA doped with 2% La showed excellent performance with a calcination temperature lower than 550 oC and a time of 120 min. The study confirmed that a larger surface area provided more basic sites and enhanced surface basicity through the presence of oxygen vacancies and adsorbed OH species. Additionally, the dispersion of La species and the use of SA greatly improved the durability and CO2 adsorption capacity of the MBA in multiple cycles.

Summary: The effects of La addition and optimal Cu content on Cu/ZrO2 catalysts for selective hydrogenation of DMO to EG were investigated. La-doping effectively increased Cu dispersion and inhibited crystal phase transformation, leading to higher hydrogen activation and DMO conversion with slightly lower EG selectivity. Strong interaction between La promoters and Cu species was found to be another important active site with high catalytic efficiency in addition to Cu-0/Cu+ site on La-doped CuO/ZrO2 catalyst.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
