| description | A heterostructure material g-C<sub>3</sub>N<sub>4</sub>/SrZrO<sub>3</sub> was simply prepared by grinding and heating the mixture of SrZrO<sub>3</sub> and g-C<sub>3</sub>N<sub>4</sub>. The morphology and structure of the synthesized photocatalysts were determined by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), energy-dispersive X-ray spectroscopy (EDS), high-resolution transmission electron microscopy (HRTEM) and infrared spectra. It showed visible light absorption ability and much higher photocatalytic activity than that of pristine g-C<sub>3</sub>N<sub>4</sub> or SrZrO<sub>3</sub>. Under the optimal reaction conditions, the hydrogen production efficiency is 1222 μmol·g<sup>−1</sup>·h<sup>−1</sup> and 34 μmol·g<sup>−1</sup>·h<sup>−1</sup> under ultraviolet light irradiation and visible light irradiation, respectively. It is attributed to the higher separation efficiency of photogenerated electrons and holes between the cooperation of g-C<sub>3</sub>N<sub>4</sub> and SrZrO<sub>3</sub>, which is demonstrated by photocurrent measurements. |
