Nov 24, 2020 · Photocatalytic production of H 2 O 2 from the reduction of O 2 by semiconductor photocatalysts (e.g., graphitic carbon nitride, C 3 N 4) has been regarded as an alternative for small-scale decentralized H 2 O 2 production.

Jun 3, 2024 · Artificial photosynthesis using carbon nitride (g-C3N4) holds a great promise for sustainable and cost-effective H2O2 production, but the high carrier recombination rate impedes its efficiency.

Oct 25, 2024 · Here we show a B-doped g-C3N4 (BCN) tailored with coordinatively unsaturated FeOOH and CoOx clusters for H2O2 photosynthesis from water and oxygen without sacrificial agents.

Aug 1, 2017 · Here we report on a new basis for clean energy storage, generating H 2 O 2 from H 2 O and O 2 by organic photocatalysis. In this study, we construct an all-solid-state Z-scheme heterojunction (PIx -NCN) by assembling perylene imides (PI) on g-C 3 N 4 nanosheets (NCN), where x is a percentage weight ratio of PI to NCN.

Aug 5, 2016 · Photocatalytic H 2 O 2 production at g-C 3 N 4 could be improved by as much as 14 times in the absence of organic scavenger through a carbon vacancy-based strategy. Carbon vacancy could narrow the band gap of g-C 3 N 4 to enhance its visible light absorption.

Oct 15, 2020 · These effects significantly enhanced the H 2 O 2 photogeneration performance of g-C 3 N 4 by improving the quantum efficiency, narrowing the band gap, strengthening IPA adsorption on g-C 3 N 4, and lowering the energy barrier of the oxygen reduction reaction. This work provides an attractive and promising strategy for green H 2 O 2 production. 1.

Mar 16, 2021 · A novel nitrogen-deficient g-C3N4 sample synthesized from cyanuric acid−melamine adducts with synergistically enhanced features was employed for photocatalytic H2O2 production as a sustainable alte...

Dec 21, 2023 · The cyano contained g-C3N4 comodified by In2S3 and polypyrrole materials are prepared for the light-driven H2O2 production (895 µmol L-1 h-1) and photocatalysis-self-Fenton reaction for highly effici...

Feb 26, 2025 · Photocatalytic H2O2 generation is an efficient approach for the conversion of solar energy into chemical energy and is a potentially more sustainable alternative to the traditional anthraquinone process. Herein, porous g-C3N4 nanosheets (O-CN) were successfully prepared via a thermal polycondensation-assisted oxida

Mar 10, 2025 · In this study, a high-crystallinity boron-doped g-C3N4 (BCCN) was designed and applied for photocatalytic H2O2 synthesis. Photoelectrochemical experiments demonstrated that enhanced crystallinity reduces charge transfer resistance, while DFT calculations revealed that boron doping redistributes the HOMO and LUMO orbitals of g-C3N4.
