Surface engineering of colloidal quaternary chalcogenide CuZnSnS nanocrystals: a potential low-cost photocatalyst for water remediation.

Colloidal route synthesis of quaternary compound CZTS (CuZnSnS) has been anticipated with an inimitable combination of coordinating ligands and solvents using the hot injection technique. CZTS is recognized as one of the worthiest materials for photo-voltaic/catalytic applications due to its exclusive properties (viz., non-toxic, economical, direct bandgap, high absorbance coefficient, etc.
