Carbon dots/Cu2MoS4 nanosheets hybrids with efficient photoelectrochemical performance.

We report a facile fabrication of carbon dots (CDs)/Cu 2 MoS 4 nanosheets hybrid photocathodes for potential application in photoelectrochemical cells (PECs). The structural, morphological and photoelectrochemical characteristics are studied. Compared with pristine Cu 2 MoS 4 , the photoelectrocatalytic activity of CDs/Cu 2 MoS 4 nanosheets composites was significantly improved under artificial solar light, as confirmed by the lowered onset potential and improved photocurrent response. Our study provides useful insights in the design of low-cost and earth abundant materials for high-efficiency solar fuel production. [ABSTRACT FROM AUTHOR]
