摘要

光电催化分水制氢具有巨大的工业应用潜力。本文制备了 Pt/C3N4-NVs 作为光阳极，在 300 W 氙灯照明下，当偏置电压为 1.23 V（相对于 RHE）时，其光电催化制氢率达到 717.82 μmol-g-1-h-1，且光电流密度在 24 小时内保持稳定。

Rapid Joule heating synthesis of Pt/C3N4-NVs for photoelectrocatalytic water splitting to 0H2†

Photoelectrocatalytic water splitting to produce hydrogen has great potential for industrial applications. Herein, Pt/C3N4-NVs was prepared as photoanodes, its photoelectrocatalytic hydrogen generation rate reached 717.82 μmol·g-1·h-1 under 300 W Xenon lamp illumination when the bias voltage was 1.23 V (vs. RHE), and the photocurrent density remained stable for 24 h. This work demonstrated that the C3N4-based photocatalysts have good photostability and prospects for industrial applications.
