Hybridized Mechanical and Solar Energy-Driven Self-Powered Hydrogen Production.

ABSTRACT: Photoelectrochemical hydrogen generation is a promising approach to address the environmental pollution and energy crisis. In this work, we present a hybridized mechanical and solar energy-driven self-powered hydrogen production system. A rotatory disc-shaped triboelectric nanogenerator was employed to harvest mechanical energy from water and functions as a sufficient external power source. WO₃/BiVO₄ heterojunction photoanode was synthesized in a PEC water-splitting cell to produce H₂. After transformation and rectification, the peak current reaches 0.1 mA at the rotation speed of 60 rpm. In this case, the H₂ evolution process only occurs with sunlight irradiation. When the rotation speed is over 130 rpm, the peak photocurrent and peak dark curre
