Description
Summary:Photoelectrochemical water splitting is one of the viable approaches to produce clean hydrogen energy from water. Herein, we report MoS /Si-heterojunction (HJ) photocathode for PEC H production. The MoS /Si-HJ photocathode exhibits exceptional PEC H production performance with a maximum photocurrent density of 36.33 mA/cm , open circuit potential of 0.5 V vs. RHE and achieves improved long-term stability up to 10 h of reaction time. The photocurrent density achieved by MoS /Si-HJ photocathode is significantly higher than most of the MoS coupled Si-based photocathodes reported elsewhere, indicating excellent PEC H production performance.
