MoS₂-CdS composite for photocatalytic reduction of hexavalent chromium and thin film optoelectronic device applications.

ABSTRACT: We introduce an enhanced light-harvesting MoS₂-based nanocomposite exhibiting improved solar light induced photocurrent generation, both in solution and solid phases. The MoS₂-CdS composite was synthesized via easy to achieve, cost effective, two-step solution process for the photocatalytic potassium dichromate [Cr(VI)] reduction and photocurrent generation in thin-film optoelectronic devices. Incorporating 10 wt% MoS₂ into the composite increased the degradation efficiency of CdS from 43.9 to 91.9%. Furthermore, the MoS₂-CdS composite demonstrated a 2.88-fold increase in the degradation rate constant and a 2.15% enhancement in the apparent quantum yield compared to controlled CdS. Additionally, the electrical power consumption per order decrease
