“…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.

The photoelectrochemical production and degradation properties of hydrogen peroxide (H O ) were investigated on a WO /BiVO photoanode in an aqueous electrolyte of hydrogen carbonate (HCO ). High concentrations of HCO species rather than CO species inhibited the oxidative degradation of H O on the WO /BiVO photoanode, resulting in effective oxidative H O generation and accumulation from water (H O). Moreover, the Au cathode facilitated two-electron reduction of oxygen (O ), resulting in reductive H O production with high current efficiency. Combining the WO /BiVO photoanode with a HCO electrolyte and an Au cathode also produced a clean and promising design for a photoelectrode system specializing in H O production (η (H O )≈50 %, η (H O )≈90 %) even without applied voltage between the photoanode and cathode under simulated solar light through a two-photon process; this achieved effective H O production when using an Au-supported porous BiVO photocatalyst sheet.

“…The light-driven formation of H 2 O 2 has received increased attention in recent decades [3][4][5][6][7][8]. The process involves light capture on the photocatalyst, charge separation under light irradiation, charge transfer to the surface of the photocatalyst, water/alcohol oxidation by photo-generated holes, and the reduction of dioxygen by photo-generated electrons [9][10][11].…”

Enhancing Light-Driven Production of Hydrogen Peroxide by Anchoring Au onto C3N4 Catalysts

et al. 2018

Light-driven production of hydrogen peroxide (H 2 O 2 ) is a green and sustainable way to achieve solar-to-chemical energy conversion. During such a conversion, both the high activity and the stability of catalysts were critical. We prepared an Au-supported C 3 N 4 catalyst-i.e., Au/C 3 N 4 -500(N 2 )-by strongly anchoring Au nanoparticles (~5 nm) onto a C 3 N 4 matrix-which simultaneously enhanced the activity towards the photosynthesis of H 2 O 2 and the stability when it was reused. The yield of H 2 O 2 reached 1320 µmol L −1 on Au/C 3 N 4 -500(N 2 ) after 4 h of light irradiation in an acidic solution (pH 3), which was higher than that (1067 µmol L −1 ) of the control sample Au/C 3 N 4 -500(Air) and 2.3 times higher than that of the pristine C 3 N 4 . Particularly, the catalyst Au/C 3 N 4 -500(N 2 ) retained a much higher stability. The yield of H 2 O 2 had a marginal decrease on the spent catalyst-i.e., 98% yield was kept. In comparison, only 70% yield was obtained from the spent control catalyst. The robust anchoring of Au onto C 3 N 4 improved their interaction, which remarkably decreased the Au leaching when it was used and avoided the aggregation and aging of Au particles. Minimal Au leaching was detected on the spent catalyst. The kinetic analyses indicated that the highest formation rate of H 2 O 2 was achieved on the Au/C 3 N 4 -500(N 2 ) catalyst. The decomposition tests and kinetic behaviors of H 2 O 2 were also carried out. These findings suggested that the formation rate of H 2 O 2 could be a determining factor for efficient production of H 2 O 2 .
