Enhanced photocatalytic H2 production of CdS by the introduction of Cd vacancies
{{output}}
CdS nanoparticles with engineered Cd vacancies were synthesized by adjusting the starting materials of CdCl2·2.5H2O and Na2S·9H2O. Optimal performance was achieved at a Cd : S ratio of 1 : 2, yielding a 3.4-fold increase in hydrogen production (from 0.56 to ... ...
