Design and development of robust, stable and efficient photocatalysts is still a significant challenge in photocatalytic field. Herein, a 3D/1D CoS x /Mn 0.3 Cd 0.7 S heterojunction photocatalysts were prepared by coupling ZIF-67 polyhedron derived 3D CoS x with 1D rod-shaped Mn 0.3 Cd 0.7 S via solvothermal procedure, which greatly improved the efficiency of charge separation and photocatalytic H 2 production activity. Among these heterojunctions, CoS x /Mn 0.3 Cd 0.7 S-8, with a theoretical molar ratio of 1:8, demonstrated the best photocatal...
