Complexes Based on Zinc and Cadmium for Visible Light-Driven Hydrogen Production
Photocatalytic water decomposition using solar energy is one of the most effective hydrogen production technologies. The development of a structurally stable photocatalyst for hydrogen production without cocatalysts and photosensitizers remains a great challenge. In this paper, complex photocatalyst compounds <b>1</b> and <b>2</b> with different crystal structures were designed and obtained by connecting the 4'-(2,4-disulfophenyl)-4,2':6',4″-terpyridine organic ligands with Zn(Ac)<sub>2</sub>·2H<sub>2</sub>O and CdCO<sub>3</sub>. These products were used for photocatalytic hydrogen production separately, and the hydrogen production rates of compounds <b>1</b> and <b>2</b> were 0.66 mol·mol<sup>-1</sup>·h<sup>-1</sup> and 0.12 mol·mol<sup>-1</sup>·h<sup>-1</sup>, respectively, without the addition of any cocatalysts and photosensitizers, and their charge separation and transfer processes were verified by PL, time-resolved PL, and photocurrent. Compound <b>1</b> was tested in 6 cycles over 18 h and showed high stability and reproducibility.
