Abstract

Abstract: In this study, with silicon carbide as a pyroelectric catalyst, the reactor was alternatively removed between a hot water bath and a cold water bath, which ensured the cold-hot circulation within 300–333 K at room temperature. Then the pyroelectric performance of silicon carbide was utilized in hydrogen evolution from water splitting. With methanol as the sacrificial agent, the hydrogen yield after 20 cycles was up to 32.84 μmol/g. Silicon carbide demonstrates high catalytic activity and together with its chemical stability, it shows potential in hydrogen production from water splitting under cold-hot alternation.
