The development of high-efficiency and durable bifunctional electrocatalysts for both the oxygen reduction reaction (ORR) evolution (OER) is critical widespread application rechargeable zinc-air (Zn-air) batteries. This calls rational screening targeted ORR/OER components precise control their atomic electronic structures to produce synergistic effects.

Heterogeneous catalysts containing diatomic sites are often hypothesized to have distinctive reactivity due synergistic effects, but there limited approaches that enable the convenient production of (DACs) with diverse metal combinations. Here, we present a general synthetic strategy for constructing DAC library across wide spectrum homonuclear (Fe2, Co2, Ni2, Cu2, Mn2, and Pd2) heteronuclear (Fe-Cu, Fe-Ni, Cu-Mn, Cu-Co) bimetal centers. This is based on an encapsulation-pyrolysis approach,...
Great enthusiasm in single-atom catalysts for various catalytic reactions continues to heat up. However, the poor activity of existing single/dual-metal-atom does not meet actual requirement.

Oxide-derived copper (OD-Cu) is the most efficient and likely practical electrocatalyst for CO 2 reduction toward multicarbon products. However, inevitable but poorly understood reconstruction from pristine state to working of OD-Cu under strong conditions largely hinders rational construction catalysts products, especially C 3 products like n-propanol. Here, we simulate CuO Cu O into their derived by molecular dynamics, revealing that CuO-derived (CuOD-Cu) intrinsically has a richer...
Selective aerobic epoxidation of alkenes without any additives is great industrial importance but still challenging because the competitive side reactions including C═C bond cleavage and isomerization are difficult to avoid.
