Enhancing Hydrogen Evolution Reaction via Synergistic Interaction between the [Mo3S13]2- Cluster Co-Catalyst and WSe2 Photocathode
Abstract
A thiomolybdate [Mo<sub>3</sub>S<sub>13</sub>]<sup>2-</sup> nanocluster is a promising catalyst for hydrogen evolution reaction (HER) due to the high number of active edge sites. In this work, thiomolybdate cluster films are prepared by spin-coating of a (NH<sub>4</sub>)<sub>2</sub>Mo<sub>3</sub>S<sub>13</sub> solution both on FTO glass substrates as hydrogen evolving electrodes and on highly 00.1-textured WSe<sub>2</sub> for photoelectrochemical water splitting. As an electrocatalyst, [Mo<sub>3</sub>S<sub>13</sub>]<sup>2-</sup> clusters demonstrate a low overpotential of 220 mV at 10 mA cm<sup>-2</sup> in 0.5 M H<sub>2</sub>SO<sub>4</sub> electrolyte (pH 0.3) and remain structurally stable during the electrochemical cycling as revealed by in situ Raman spectroscopy. Moreover, as a co-catalyst on WSe<sub>2</sub>, [Mo<sub>3</sub>S<sub>13</sub>]<sup>2-</sup> clusters enhance the photocurrent substantially by more than two orders of magnitude (from 0.02 to 2.8 mA cm<sup>-2</sup> at 0 V vs RHE). The synergistic interactions between the photoelectrode and catalyst, i.e., surface passivation and band bending modification by the [Mo<sub>3</sub>S<sub>13</sub>]<sup>2-</sup> cluster film, promoted HER catalytic activity of [Mo<sub>3</sub>S<sub>13</sub>]<sup>2-</sup> clusters influenced by the WSe<sub>2</sub> support, are revealed by intensity-modulated photocurrent spectroscopy and density functional theory calculations, respectively. The band alignment of the WSe<sub>2</sub>/[Mo<sub>3</sub>S<sub>13</sub>]<sup>2-</sup> heterojunction, which facilitates the electron injection, is determined by correlating UV-vis with photoelectron yield spectroscopy results. © 2022 The Authors.
