Morphology-Dependent ZnO/MoS₂ Heterostructures for Enhanced Photoelectrochemical Water Splitting

ACS Applied Energy Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 15, 2025

This study reports the synthesis of ZnO nanosheets, nanorods, and nanotubes through electrodeposition, followed by deposition MoS2 layers using RF magnetron sputtering to create ZnO/MoS2 heterostructures. The morphological structural properties these materials were characterized various techniques, including X-ray diffraction, Raman spectroscopy, scanning electron microscopy, transmission photoelectron UV–visible spectroscopy. photoelectrochemical (PEC) performance synthesized heterostructures for water splitting was evaluated. Results indicate that morphology significantly influences PEC activity heterostructure with exhibited highest performance, achieving a photocurrent density ∼1.28 mA/cm2 at 1.65 V versus reversible hydrogen electrode, which is 2.5 times greater than pristine nanotube photoanode. suggests can be promising photoanodes efficient production oxidation.

Improving Charge Transfer Beyond Conventional Heterojunction Photoelectrodes: Fundamentals, Strategies and Applications

Advanced Functional Materials, Год журнала: 2024, Номер 34(46)

Опубликована: Июнь 20, 2024

Abstract Photoelectrochemical (PEC) cells are regarded as a promising approach to convert sunlight chemical fuels, whereas the serious photo‐induced charge recombination of semiconductor photoelectrode hinders its solar conversion efficiency. Over past few decades, designing and constructing heterojunction photoelectrodes via thermodynamically favorable transfer have been proven be effective in boosting separation. However, conventional construction strategy generally introduces incompatible, nonconformal, or defective interfaces, leaving considerable room improve efficiency photoelectrodes. To compensate for unsatisfied efficiency, some novel strategies, such grain boundary engineering, band gap field‐effected etc., adopted provide additional driving force, which significantly improves In this review, these strategies discussed beyond construction, prospects development applications photoanodes also proposed.
