Summary: Selective catalytic oxidation is crucial in fine chemical and petrochemical industries, but it is challenging to achieve selective production of target products in the presence of multiple reaction paths. Single atom catalysts, different from nanoclusters and nanoparticles, offer opportunities for highly selective catalytic oxidation. This review summarizes recent advances in using novel catalytic materials for challenging selective oxidation reactions, including methane oxidation, alcohol oxidation, alkene epoxidation, and carbon monoxide oxidation. The key factors affecting catalytic performance, such as the electronic and geometric structures of single atoms, nanoclusters, and nanoparticles, are discussed. Understanding the active species, structures, activity-structure relationship, and mechanisms of these catalytic systems are highlighted, along with current challenges and future developments, aiming to guide the design of efficient and highly selective catalysts for heterogeneous oxidation reactions and to better understand their catalytic behaviors in a unified way.

Summary: The importance of transition metal catalysis lies in its wide range of applications, including the synthesis of chemicals, natural products, and pharmaceuticals. However, a relatively new application is the catalysis of new-to-nature reactions inside living cells. The complex environment of living cells poses challenges to transition metal catalysts due to the potential inhibition or deactivation by various biological components. In this review, we summarize the current progress in the field of transition metal catalysis, focusing on the evaluation of catalysis efficiency under living cell and biological conditions. Catalyst poisoning is a common issue in this field, and we suggest that future research should explore physical and kinetic protection strategies to enhance the reactivity of catalysts in cells.

Summary: This study investigated the catalytic performance of three types of alumina-supported bimetallic Ni-Cu catalysts in the conversion of levulinic acid into gamma-valerolactone and 2-methyltetrahydrofuran. It was found that the catalysts prepared on ordered mesoporous alumina supports displayed superior activity compared to those prepared on commercial non-ordered mesoporous alumina supports. Among them, Ni-Cu-OMA, prepared via the one-pot evaporation-induced self-assembly strategy, exhibited the best catalytic performance.

Summary: This study investigates the role of platinum nanoparticles loaded on MXene nanosheets as a sulfur host and catalyst in the solid-liquid-solid chemical transformation of sulfur species. It finds that the high performance of the catalyst originates from electron transfer between the catalyst and LiPSs, which lowers the nucleation barrier and accelerates the liquid-solid conversion, thereby improving the reaction kinetics and reducing the accumulation of LiPSs in Li-S batteries. The findings suggest that electronic modulation between catalysts and LiPSs is a generalizable strategy to optimize energy conversion efficiency in Li-S batteries.
