| titleOfInvention | Preparation method of composite photocatalyst for efficient generation of hydrogen peroxide without sacrificial agent under visible light |
| abstract | The photocatalytic production of hydrogen peroxide by g ‑ C3N4 using water and oxygen is a promising and sustainable method. However, the yield of pure g - C3N4 to produce H2O2 is not ideal due to limited light absorption, fast photogenerated electron - hole recombination and poor surface electron transfer. Therefore, high-temperature calcination and hydrothermal methods were employed to modify the porous g- C3N4 to synthesize p - P1CN / CQDs25 composite photocatalysts by incorporating phosphorus and supporting carbon quantum dots. Phosphorus acts as a bridge for electron transfer, inducing electrons into CQDs, and CQDs act as electron-trapping materials to capture and stabilize photogenerated electrons. Due to the unique optical properties of CQDs, they can also enhance light absorption. The p‑P 1 CN/CQDs 25 exhibited highly enhanced H 2 O 2 generation activity under visible light without the addition of sacrificial agents and oxygen sparging, and the H 2 O 2 generation amount was as high as 494 μM/L after 5 h of reaction , the generation rate constant K f is 238 μM h ‑1 . |
