Engineering sulfur vacancies and photothermal effects in a CoAl 2 O 4 /MnCdS S-scheme heterojunction for broad-spectrum photocatalytic hydrogen production

An S-scheme CoAl 2 O 4 /MnCdS-Vs photocatalyst was fabricated via a three-step method for photocatalytic H 2 evolution. Its photothermal effect synergizes with sulfur vacancies to reduce reaction activation energy and accelerate surface reaction kinetics.
