| description | <p dir="ltr">MoSe<sub>2</sub>/1 D TiO<sub>2</sub> nanorods (NRs) heterojunction assembly was systematically fabricated, and its photoelectrocatalytic properties were investigated. The fabrication process involves the growth of 1D TiO<sub>2</sub> NRs arrays on FTO substrates using hydrothermal synthesis followed by the deposition of MoSe<sub>2</sub> nanosheets on the TiO<sub>2</sub> NRs using radiofrequency magnetron sputtering (RF magnetron sputtering). The photoelectrochemical properties of the heterojunction were explored and optimized as a function of the thickness of the MoSe<sub>2</sub> layer, which was controlled by the sputtering time. The MoSe<sub>2</sub> grows perpendicularly on TiO<sub>2</sub> NRs in a 2D layered structure, maximizing the exposed active edges, an essential aspect that permits maximum exploitation of deposited MoSe<sub>2</sub>. Compared to pure TiO<sub>2</sub> NRs, the heterojunction nanostructured assembly displayed excellent spectral and photoelectrochemical properties, including more surface oxygen vacancies, enhanced visible-light absorption, higher photocurrent response, and decreased charge transfer resistance. In particular, the sample synthesized by sputtering of MoSe<sub>2</sub> for 90 s, i.e., MoSe<sub>2</sub>@TiO<sub>2</sub>-90 s, depicted the highest current density (1.86 mA cm<sup>−2</sup> at 0.5 V vs. Ag/AgCl) compared to other samples. The excellent photoelectrochemical activity of the heterojunction stemmed from the synergy between tailored loading of MoSe<sub>2</sub> nanosheets and the 1D structure of TiO<sub>2</sub> NRs, which afford a high surface/volume ratio, effective charge separation, fast electron transfer, and easy accessibility to the MoSe<sub>2</sub> active edges. These factors boost the catalytic activity.</p><h2>Other Information</h2><p dir="ltr">Published in: Applied Surface Science<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.apsusc.2023.157205" target="_blank">https://dx.doi.org/10.1016/j.apsusc.2023.157205</a></p> |
