- Abstract
- Herein, noble-metal free Ni-Te/Ni-P dual co-catalysts are investigated as attractive candidates for improving the photoelectrochemical (PEC) performance of CdTe photocathodes. The Ni-Te/Ni-P dual co-catalysts are deposited on CdTe photocathodes via pulse-reverse electrodeposition and post annealing. The Ni-Te/Ni-P catalyzed CdTe photocathodes show a remarkable PEC performance, especially in terms of the photocurrent density, which is approximately 11.06 times higher than that of the pristine CdTe photocathode. The Ni-Te/Ni-P dual co-catalysts boost the catalytic activity via enhanced charge transfer and surface reaction kinetics. The photogenerated electrons and holes are effectively separated by the Schottky contact between the Ni-Te/Ni-P dual co-catalysts and the CdTe absorbing layer. Thus, the rational design of the CdTe photocathode with the Ni-Te/Ni-P dual co-catalysts can dramatically enhance the PEC performance of the CdTe photocathodes.& COPY; 2022 Hydrogen Energy Publications LLC.
