The Vis-NIR light-responsive direct Z-scheme LaNiO₃/CdS nanohybrid was synthesized via a refluxing method, fully characterized, and used in photocatalytic H₂ evolution. The H₂ evolved over LaNiO₃/CdS photocatalyst in 5 h was 737 μmol under visible light irradiation, which was 4.3 times that over CdS (172 μmol) ascribed to the formed heterojunction between LaNiO₃ and CdS. Moreover, the introduced LaNiO₃ extended the light absorption to the NIR region and the H₂ evolution increased to 996 μmol under Vis-NIR light irradiation. LaNiO₃ exhibited upconversion luminescence at 406 and 628 nm when excited at 808 nm, which means that LaNiO₃ can generate charge carriers under NIR light irradiation, thereby further improving the efficiency of its photocatalytic H₂ evolution.
