The combination of a wide bandgap Zinc oxide (ZnO ~3.4 eV) semiconductor photocatalyst with typical metallic
sulphides, namely, silver sulphide (Ag2S), ferric sulphide (FeS) and nickel sulphide (NiS), all of a similar ...

This study investigates the synthesis, characterisation, and application of a visible-light activated binary
nanocomposite catalyst for the degradation of phenol in water. Zinc oxide with a wide direct band gap (3.4 eV)
is ...

Silver sulphide (Ag2S) and zinc oxide (ZnO) nanoparticles were synthesized through a sol-gel method. The Ag
constituent of the ternary was achieved by photodesposition of the binary Ag2S/ZnO resulting in a color
change ...
The aim of this work was to investigate a new, simple, one-pot combustion synthesis technique for creating sulphur-based CuS/ZnS p-n heterojunction nanocomposite photocatalysts. This study examined the photocatalytic ...
