“…In addition, several perovskite-type heterojuction nanocomposites have already been proposed and prepared for photocatalytic reaction in the literature (27)(28)(29). The perovskite-type materials could be combined with other metal-free semiconductor materials that have matching band gaps to form Z-scheme heterostructure photocatalytic composite materials, which can transfer the photogenerated holes or electros from one semiconductor to another, thereby they not only reduce the recombination of carriers but also acquire more wide range of light response areas (30)(31)(32). S. Acharya et al loaded LaFeO3 nanoparticles on RGO nanosphere, which promoted the H2 evolution rate more than two fold than neat LFO (33).…”

A binary direct Z-scheme LaNiO 3 /g-C 3 N 4 nanocomposite photocatalyst consisted with LaNiO 3 nanoparticles and g-C 3 N 4 nanosheets was successfully synthesized by means of mechanical mixing and solvothermal methods in order to improve the photocatalytic water splitting activity. The as-prepared materials were characterized by powder X-ray diffraction (XRD), Scanning Electron microscope (SEM), Transmission Electron microscope (TEM), X-ray photoelectron spectroscope (XPS), Fourier Transform Infrared Spectroscopy (FT-IR) and N 2 adsorption-desorption experiments, respectively, demonstrating the formation of interfacial interaction and heterogeneous structure in LaNiO 3 /g-C 3 N 4 nanocomposites. Under UV-light irradiation, the LaNiO 3 /g-C 3 N 4 samples which without the addition of any noble metal as co-catalyst behaved enhanced photocatalytic water splitting activity compared with pure LaNiO 3 and g-C 3 N 4 , owing to the Z-scheme charge carrier transfer pathway. Especially, the LaNiO 3 /70%g-C 3 N 4 nanocomposite reach an optimal yield of up to 3392.50 µmol g -1 in 5 h and held a maximum H 2 evolution rate of 678.5 µmol h -1 g -1 that was 5 times higher than that of pure LaNiO 3 .
