Key Points

Summarize fundamental principles and experimental considerations of photocatalytic water splitting while surveying heterogeneous photocatalyst materials developed for solar hydrogen and oxygen production.
Reviewed 361 published studies assessing heterogeneous photocatalytic systems and reaction mechanisms.
Categorized photocatalysts evaluated for total water splitting and half-reactions using sacrificial reagents as electron donors or acceptors.
Classified active compositions based on transition metal d-band electronic structures, including d0 and d10 oxides, (oxy)sulfides, and (oxy)nitrides.
Cataloged diverse metal oxide systems containing transition metal cations with d0 and d10 electronic configurations capable of catalyzing water cleavage.
Identified non-oxide photocatalysts, particularly metal (oxy)sulfides and (oxy)nitrides, as effective systems for extending solar absorption into the visible-light spectrum.
Established core relationships between crystal structure, electronic band alignment, charge separation dynamics, and overall solar-to-hydrogen conversion efficiency.
