Abstract Semiconductor photocatalysis is recognized as a promising strategy to simultaneously address energy needs and environmental pollution. Titanium dioxide (TiO 2 ) has been investigated for such applications due to its low cost, nontoxicity, and high chemical stability. However, pristine TiO 2 still suffers from low utilization of visible light and high photogenerated‐charge‐carrier recombination rate. Recently, TiO 2 photocatalysts modified by dual cocatalysts with different functions have attracted much attention due to the extended light absorption, enhanced reactant adsorption, and promoted charge‐carrier‐separation efficiency granted by various cocatalysts. Recent progress on the component and structural design of dual cocatalysts in TiO 2 photocatalysts is summarized. Depending on their components, dual cocatalysts decorated on TiO 2 photocatalysts can be divided into the following categories: bimetallic cocatalysts, metal–metal oxide/sulfide cocatalysts, metal–graphene cocatalysts, and metal oxide/sulfide–graphene cocatalysts. Depending on their architecture, they can be categorized into randomly deposited binary cocatalysts, facet‐dependent selective‐deposition binary cocatalysts, and core–shell structural binary cocatalysts. Concluding perspectives on the challenges and opportunities for the further exploration of dual cocatalyst–modified TiO 2 photocatalysts are presented.
