| 英文摘要 | Metal oxide semiconductor-based photo(electro)catalysis has drawn increasing attention due to its prominent applications in solar energy conversion and environmental remediation. The photogenerated valence-band hole and conduction-band electron diffuse to the metal oxide/solution interface and trigger subsequent chemical conversions involving multiple proton-coupled electron (hole) transfer (PCET) steps to reconstruct chemical bonds. We review herein our recent work on regulating such PCET processes in photocatalytic oxygen reduction and water oxidation. The reaction thermodynamics, kinetics, and PCET pathways can be tuned by controlling the crystal facet and surface structure. Reductive conversion of organic halides by PCET on pristine or modified TiO2 as well as its unique kinetic features are also discussed. Such mechanistic fundamentals of interfacial reactions could guide development of photocatalysts with improved efficiency and desired selectivity. |
