Summary: Electrochemical reduction of nitrate to ammonia has been limited by poor selectivity and stability of monometallic and bimetallic catalysts in acidic environments. In this study, a multielementalloy nanoparticle catalyst with dispersed Ru (Ru-MEA) was developed, showing improved reactivity and high NH3 faradaic efficiency in acidic wastewater. The Ru-MEA catalyst demonstrated good stability over three hours. This work provides a potential systematic and efficient catalyst discovery process for various applications.

Summary: Two-dimensional materials exhibit unique advantages in catalysis. This study discovered that melamine can induce the directional growth of cobalt-based catalysts, resulting in ultra-thin two-dimensional hexagonal nanosheets. The CoO hexagonal porous nanosheets (HPNs) formed from these nanosheets under high temperature conditions have a surface area 11.3 times larger than that of nanoparticles. Embedding monoatomic ruthenium in the CoO HPNs enhances the catalyst's charge storage and transfer centers, leading to improved catalytic performance in the oxygen evolution reaction.

Summary: In this study, it was found that MnO with lower specific surface area (SSA) exhibited a higher dispersion of Ru under reducing conditions compared to MnO with higher SSA. This enhanced dispersion led to improved catalytic activity and stability of Ru catalysts for the hydrogenolysis of diphenyl ether. The presence of enriched surface oxygen in MnO with lower SSA played a key role in anchoring Ru species and preventing their aggregation.

Summary: Developing efficient and green catalytic systems for the synthesis of alicyclic amines via hydrogenation of nitroaromatics is highly desired. In this study, Ru-Pd dual active site catalysts anchored on air-exfoliated carbon nitride were developed and showed superior performance in the hydrogenation of nitrobenzene to cyclohexylamine. The Ru-Pd catalysts exhibited a higher CHA production rate compared to single Ru or Pd based catalysts and showed enhanced catalytic activity due to the highly dispersed Ru-N-x and Pd-N-x at a nanoscale distance.

Summary: Selective hydrogenation of substituted nitroarenes to obtain amines is an important reaction. In this study, a series of iron compounds supported Pt catalysts were synthesized by immobilizing Pt nanoparticles (NPs) on FeOOH, Fe3O4, and alpha-Fe2O3 nanorods using a liquid phase reduction method. The performance of the catalysts was evaluated using the chemoselective hydrogenation of 3-nitrostyrene to 3-aminostyrene as a probe reaction. The results showed that Pt/FeOOH exhibited the highest selectivity and activity. The presence of pores and -OH groups in the FeOOH support could tune the electronic structure of Pt NPs, and the positive charge of Pt NPs on FeOOH was identified as a key factor for improving the catalytic performance.

Summary: Intercalation of Zn2+ ions into MXene resulted in shrinkage of adjacent MXene layers and increased Li+ storage capacity. The Zn2+ ions lost electrons while Ti in MXene gained electrons, and low-F surface functional groups were formed. After a certain number of cycles, the interlayer distance increased, promoting ion transport and providing a larger space for lithium storage.

Summary: The selective oxidation of 2,5-bis(hydroxymethyl)furan (BHMF) using modified carbon nanotube-supported Pd-based catalysts has shown promising results in producing 2,5-furandicarboxylic acid (FDCA). The catalysts achieved a high FDCA yield of 93.0% with full conversion of BHMF, outperforming the traditional route using 5-hydroxymethylfurfural (HMF) as substrates. The participation of PdHx active species with metallic Pd is believed to contribute to the improved performance. This research opens up new opportunities for synthesizing other valuable oxygenates using BHMF as an alternative feedstock.

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.
