The light-driven CO2 reduction to multi-carbon products is especially meaningful, while the low efficiency of multi-electron transfer and sluggish C-C coupling greatly hinder its development. Herein, we report a photocatalyst comprising P Cu dual sites anchored on graphitic carbon nitride (P/Cu SAs@CN), which achieves high C2 H6 evolution rate 616.6 μmol g-1 h-1 in reducing hydrocarbons. detailed spectroscopic characterizations identify formation charge-enriched sites, where isolated atoms serve as hole capture during photocatalysis. Theoretical simulations combined with situ FTIR measurement reveal kinetically feasible process for intermediate (*OC-COH) confirm favorable production P/Cu SAs@CN photocatalyst. This work offers new insights into design atomic precision toward highly efficient photocatalytic conversion value-added products.

Nickel-based catalysts have been regarded as one of the most promising electrocatalysts for urea oxidation reaction (UOR), however, their activity is largely limited by inevitable self-oxidation Ni species (NSOR) during UOR. Here, we proposed an interface chemistry modulation strategy to trigger occurrence UOR before NSOR via constructing a 2D/2D heterostructure that consists ultrathin NiO anchored Ru-Co dual-atom support (Ru-Co DAS/NiO). Operando spectroscopic characterizations confirm this unique triggering mechanism on surface DAS/NiO. Consequently, fabricated catalyst exhibits outstanding with low potential 1.288 V at 10 mA cm-2 and remarkable long-term durability more than 330 h operation. DFT calculations demonstrate favorable electronic structure induced heterointerface endows energetically NSOR.

Single-atom active-site catalysts have attracted significant attention in the field of photocatalytic CO2 conversion. However, designing active sites for reduction and H2 O oxidation simultaneously on a photocatalyst combining corresponding half-reaction system is still difficult. Here, we synthesized bimetallic single-atom with two compatible centers Mn Co carbon nitride (Mn1 Co1 /CN). Our experimental results density functional theory calculations showed that center promotes by accumulating photogenerated holes. In addition, activation increasing bond length angle molecules. Benefiting from synergistic effect atomic centers, Mn1 /CN exhibited CO production rate 47 μmol g-1 h-1 , which significantly higher than single-metal photocatalyst.

Benefiting from PEE adjacent Ni by four nitrogen (Ni‐N 4 ) moiety, NiCo DASs/N‐C catalyst exhibits superior ORR HER activity. In situ characterization results suggest Co (Co‐N as main active site O 2 adsorption‐activation process, which promotes formation key *OOH desorption *OH intermediate accelerate multielectron kinetics.
