Researchers developed a new type of photoanode made from heterojunction nanostructures of InS and MoS to improve efficiency in photoelectrochemical water splitting (PEC-WS).
The fabrication involved indium sputtering and sulfurization on indium-doped tin oxide glass, followed by adding 2D MoS nanosheets to enhance visible-light absorption.
The resulting photocurrent density was significantly higher than that of the individual materials, attributed to improved light absorption and better separation of photogenerated electron-hole pairs, making it a promising option for solar energy applications.
Article Abstract
Photoanodes with ample visible-light absorption and efficient photogenerated charge carrier dynamics expedite the actualization of high-efficiency photoelectrochemical water splitting (PEC-WS). Herein, we fabricated the heterojunction nanostructures of InS/MoS on indium-doped tin oxide glass substrates by indium sputtering and sulfurization, followed by the metal-organic chemical vapor deposition of 2D MoS nanosheets (NSs). The photocurrent density of InS/MoS was substantially enhanced and higher than those of pristine InS and MoS NSs. This improvement is due to the MoS NSs extending the visible-light absorption range and the type-II heterojunction enhancing the separation and transfer of photogenerated electron-hole pairs. This work offers a promising avenue toward the development of an efficient photoanode for solar-driven PEC-WS.
