Single metal atom oxides as photocatalysts: synthesis, characterization, and their role in degradation and hydrogen evolution – a mini-review

Published: April 24, 2025

Abstract This review emphasizes single-metal-atom oxides as effective photocatalysts for the degradation of organic pollutants and photocatalytic hydrogen production, particularly in enhancing systems based on dyes evolution. Single metal oxides, alone or combination with semiconductors, increase efficiency. Single-metal-atom facilitate charge separation situations involving tight bandgaps, whereas, broader they promote visible/NIR activity via up-conversion luminescence. Incorporated into Z-scheme heterostructures, diminish recombination by promoting electron transport. In this review, oxide-supported single-atom catalysts are discussed about their synthetic procedures, characterizations, reaction mechanism photocatalysis, such generation, degradation, transfer. The anchored oxide materials TiO 2 , Fe 3 O 4 Bi MoO 6 rGO, CoO. Moreover, altering doping incorporating functional groups surfaces modifies properties, indicating potential more efficient modified forthcoming studies.
