Synthesis of cuprous oxide with morphological evolution from truncated octahedral to spherical structures and their size and shape-dependent photocatalytic activities

Cu2O truncated octahedrons with different sizes, spiny spheres and spheres have been fabricated by varying the addition rates of aqueous mixture of polyvinyl pyrrolidone (PVP) and ascorbic acid (AA). The size and shape-dependent photocatalytic activities were also investigated.48
