Visible-Light Driven Efficient Overall H2O2 Production on Modified Graphitic Carbon Nitride under Ambient Conditions

Improved H2O2 photogeneration on Rb-doped-polymeric carbon nitride via enhanced O2 adsorption

“…[6][7][8][9][10] In this green process, H 2 O 2 can be produced via a one-step two-electron O 2 reduction reaction (OS-2e-ORR, eqn (1)) [11][12][13][14][15] or two-step single-electron O 2 reduction reaction (TS-2e-ORR, eqn (2) and ( 3)). [16][17][18][19][20] For the OS-2e-ORR pathway, 1,4endoperoxide intermediates are formed, while H 2 O 2 is produced via superoxide radicals for the TS-2e-ORR pathway. The oxygen absorption capacity and activation ability are critical to the catalysts for both pathways.…”

Graphitic Carbon Nitride Based Materials Towards Photoproduction of H2O2

“…This process facilitated the indirect 2e − ORR proved by the trapping experiments from BQ and ESR signals owing to the more negative CB level of the material. Another evidence from other studies also showed that the covalent functionalization of small molecules into the g‐C 3 N 4 network could accelerate not only the intramolecular charge separation but also control the charge mobility directions [214,215,218] …”
