“…In recent years, an increasing number of 3D CdS heterojunctions have been reported, 94–96 including flower-like microspheres, nanospheres, polyhedra, and other structures. Based on its unique structural characteristics, such as high specific surface area 97 and good mechanical stability, 98 3D CdS heterojunctions are widely used in the field of photocatalysis. The 3D CdS flower-like microsphere structure can be formed by the growth of nanosheets and the deposition of nanoparticles.…”
