Reasonable construction of atomically accurate photocatalysts is the key to building efficient photocatalytic systems. Herein, we propose a collective effects strategy that enables consolidation both cobalt single atoms (CoSAs) and nickel nanoparticles (NiNPs) in hierarchical porous MOFs for foundational features preparation high-performance photocatalysts. Among them, optimal sample CoSAs/Al-bpydc/NiNPs achieved CO generation rate 12.8 mmol·g–1·h–1 selectivity 91% 4 h. According experiment characterizations theoretical simulations, found CoSAs facilitate CO2 adsorption activation, while NiNPs promote hydrogen spillover transfer protons CoSAs, highlighting effect catalytic system with multiple active sites. Most importantly, as proof concept, this performance enhancement can also be applied other hierarchically MOF photocatalysts, such Al-bpdc, DUT-4, UiO-67. This work provides new insight into development optimization conversion through ingenious design
