“…Since then, wide attention have received photocatalysts based on ZnO and other inorganic semiconductors either in pristine form (TiO 2 ,,, Sb 2 O 3, WO 3 , CdS, CdTe) or as heterojunctions (WO 3 /CeO 2 , PdO x /WO 3 , N‐ and S‐doped TiO 2 , Au/BiVO 4 , Au‐supported WO 3 /BiVO 4 , and Au/TiO 2 ,). Close to these systems are photocatalysts based on carbon materials, like graphitic carbon nitrides (g‐C 3 N 4 ),, CdS/graphene oxide or Cd 3 (C 3 N 3 S 3 ) 2 coordination polymer/graphene oxide rGO . Other inorganic semiconductors capable of generating H 2 O 2 upon irradiation with light are reviewed in a recent work of Wang et al., with emphasis on application in photo degradation of organics.…”

Electroactive and conductive polymers based on transition metal complexes with salen‐type ligands are of interest as potential materials for energy storage and solar energy conversion. The easily tunable structure of monomers allows to modify polymer properties by changing either the central metal atom or the ligand substituents. Herein we report the photoelectrocatalytic activity of [MII(L)]n complexes, where M is Ni, Cu or Pd, and L is a tetradentate N,N,O,O salen‐type ligand, in the reduction of molecular oxygen to hydrogen peroxide in water solutions on polymer‐coated ITO electrodes. The photocathodic current at 0 V vs. Ag/AgCl is pH‐dependent, reaching maximum at pH 1 and dropping almost to zero at pH 12. Hydrogen peroxide production is almost quantitative (97 % efficiency measured in 1‐compartment cell). Maximal photocurrent and H2O2 concentrations achieved comprise 23 μA/cm2 and 1.3×10−3 M respectively.

Production of Hydrogen Peroxide by Photocatalytic Processes

2020

Hydrogen peroxide (H2O2) has received increasing attention because it is not only a mild and environmentally friendly oxidant for organic synthesis and environmental remediation but also a promising new liquid fuel. The production of H2O2 by photocatalysis is a sustainable process, since it uses water and oxygen as the source materials and solar light as the energy. Encouraging processes have been developed in the last decade for the photocatalytic production of H2O2. In this Review we summarize research progress in the development of processes for the photocatalytic production of H2O2. After a brief introduction emphasizing the superiorities of the photocatalytic generation of H2O2, the basic principles of establishing an efficient photocatalytic system for generating H2O2 are discussed, highlighting the advanced photocatalysts used. This Review is concluded by a brief summary and outlook for future advances in this emerging research field.

“…Photoenergy conversion offers a practical solution to the ever increasing energy and environmental issues [1][2][3]. Generally, the reactivity of a photoenergy conversion system depends heavily on its physicochemical and electrochemical structures, which can influence a series of photophysical events (i.e., photon absorption, exciton formation, charge transfer, and catalytic surface reactions) [4][5][6][7][8][9][10][11]. Steady progress is being made in developing new photoactive materials with tailored functions, particularly when visible light is used [12][13][14][15][16][17].…”
