Promoted Hydrogen Peroxide Production from Pure Water on g-C3N4 with Nitrogen Defects Constructed through Solvent-Precursor Interactions: Exploring A Complex Story in Piezo-Photocatalysis

Published: May 21, 2024

Hydrogen peroxide (H2O2) production via oxygen (O2) reduction reaction (ORR) in pure water (H2O) through graphitic carbon nitrides (g-C3N4)-based piezo-photocatalysts is an exciting approach many current studies. However, the low Lewis-acid properties of g-C3N4 limited catalytic performance because O2 adsorption efficacy. To overcome this challenge, we utilized interaction precursors with various solvents to synthesize g-C3N4, possessing multiple nitrogen-vacant species thermal shocking polymerization. Our results suggest that lack nitrogen and incident introduction oxygen-functional groups enhance Lewis acid-base interactions polarize lattices, leading enormous enhancement, roughly 7 times from optimal samples compared pristine piezo-photocatalysis. Meanwhile, also observed correlation between charge separation kinetic crystalline degree synthesized materials, which can elucidate how defects impacted outcomes. Furthermore, mechanisms were thoroughly studied, formation H2O2 proceeding radical oxidation pathways, roles light ultrasound carefully investigated. Thus, our findings not only reinforce potential view metal-free photocatalysts, accelerating understanding working principles generate based on reactions, but propose a facile one-step way for fabricating highly efficient scalable photocatalysts produce without using sacrificial agents, pushing practical application in-situ solar toward real-world scenarios.

The Journal of Physical Chemistry Letters, Journal Year: 2024, Volume and Issue: 15(42), P. 10651 - 10660

Published: Oct. 16, 2024

Carbon-based catalysts hold significant promise for photocatalytic hydrogen evolution. A critical challenge lies in optimizing the balance between electron longevity and its accumulation to avoid bottlenecks efficiency. In this study, we introduce an innovative efficient strategy rapid extraction (<100 fs) of photoinduced free electrons from a carbon-based catalyst without forming additional metal-based heterojunction hybrids. This method effectively prevents excessive carriers within catalyst. The rapidly extracted are then utilized production, resulting 10-fold increase activity compared pristine catalyst, with platinum (3 wt%) used as cocatalyst. Our significantly enhances performance state-of-the-art offering clean cost-effective producing energy. work demonstrates how fundamental understanding molecular-level phenomena their optimization can pave way delivering affordable energy society.
