To review the synthesis, functional mechanisms, and performance-enhancing roles of cocatalysts in semiconductor-driven photocatalytic reduction of carbon dioxide into hydrocarbon fuels.
Synthesized findings across the three core steps of photocatalysis: solar-light harvesting, photogenerated charge carrier separation, and surface redox reactions.
Classified cocatalyst mechanisms into charge carrier transfer promotion, catalytic selectivity enhancement, material stabilization, and suppression of unwanted side reactions.
Identified cocatalysts as the critical rate-determining factor for overcoming the sluggish kinetics of the reductive half-reaction and simultaneous water oxidation.
Showed that tailored cocatalyst interfaces significantly boost product selectivity toward target hydrocarbon fuels while preserving semiconductor stability against photocorrosion.
