Engineering the Local Atomic Environments of Indium Single-Atom Catalysts for Efficient Electrochemical Production of Hydrogen Peroxide

Erhuan Zhang et al.

Summary: Rarely reported is the in-depth understanding of local atomic environment-property relationships of p-block metal single-atom catalysts towards the 2e(-) oxygen reduction reaction (ORR). In this study, a heteroatom-modified In-based metal-organic framework-assisted approach is developed to synthesize an optimal catalyst, In SAs/NSBC, with accurately anchored single In atoms supported by hollow carbon rods. The catalyst exhibits a high H2O2 selectivity and unprecedented production rates in different electrolytes, providing practical guidance for H2O2 electrosynthesis and enabling the design of high-performance single-atom materials.

Catalytic Interplay of Ga, Pt, and Ce on the Alumina Surface Enabling High Activity, Selectivity, and Stability in Propane Dehydrogenation

Han Chang Kwon et al.

Summary: Based on Pt, bimetallic catalysts have been widely studied in propane dehydrogenation due to their high activity in C-H cleavage and propylene selectivity. Recent research has shown that the selective generation of atomically dispersed Ce3+ on the gamma-Al2O3 surface is crucial for stabilizing Pt-0 species and achieving high catalytic activity, selectivity, and longevity in PDH. Excessive Ce loading can lead to a more severe loss of catalytic activity and selectivity.
