Key Points

Higher exciton binding energy limits free charge carrier generation, leading to reduced hydrogen peroxide production efficiency.
Photocatalytic production of hydrogen peroxide from resorcinol-formaldehyde resin was significantly enhanced by modulating exciton binding energy, reaching optimal levels.
The method utilized S-scheme heterojunction construction to effectively regulate exciton binding energy, markedly increasing overall photocatalytic performance.
This approach suggests future possibilities for improving efficiency in photocatalytic systems, although practical applications may require further exploration.
