Abstract

In this study, inorganic–organic hybrid CdSe(en)_0.5 nanosheet (NS) was developed on Cd foil via the microwave-assisted (MW) method with different MW irradiation cycles. Furthermore, the photoelectrochemical (PEC) performance of the mother material was improved through a second hydrothermal method with different time variations (3, 6, and 12 h at 160 °C). After the second hydrothermal, organic moieties were removed, and a porous photoanode was obtained. The optimized CdSe-6H photoanode showed a photocurrent density of 7.4 mA cm⁻² (0 V vs Ag/AgCl) with 272 μmol cm⁻²/3h hydrogen gas evolution under one sun illumination. The enhanced PEC performance was attributed to the topotactic transformation, improved light absorbance, enhanced charge separation, and improved surface area. This work offers a rational approach for building inorganic–organic electrodes through the MW method and porous photoanode for PEC hydrogen production.
