Cadmium sulfide is a II-VI compound semiconductor with a direct band gap in the visible, examined mostly as a photocatalyst and as a quantum dot. Immobilising the sulfide on a polymer support was an early route to photocatalytic hydrogen sulfide splitting ^[1]. Embedding gold quantum dots in hollow sulfide spheres raises the hydrogen evolution rate by shortening the path to the surface ^[2]. Interfacial charge transfer from a sulfide quantum dot into a monolayer dichalcogenide can be followed directly ^[3]. Pairing a zinc-cadmium sulfide with graphitic carbon nitride gives a type-II heterojunction ^[4]. Sequential proton-coupled electron transfer at a sulfide surface converts nitrobenzene to aniline ^[5].
