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

Abstract

Photoelectrocatalytic water splitting to produce hydrogen has great potential for industrial applications. Herein, Pt/C₃N₄-NVs was prepared as a photoanode, 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.
