Surface disorder engineering in ZnCdS for cocatalyst free visible light driven hydrogen production

Metal chalcogenide solid solution, especially ZnCdS, has been intensively investigated in photocatalytic H2 generation due to their cost-effective synthetic procedure and adjustable band structures. In this work, we report on the defect engineering of ZnCdS with surface disorder layer by simple room temperature Li-ethylenediamine (Li-EDA) treatment. Experimental results confirm the formation of unusual Zn and S dual vacancies, where rich S...
