ABSTRACT The micro‐morphology of photocatalytic materials has a great influence on their performance. Quantum dots can provide the plasmon resonance effect and broaden wavelength range light absorption. In this study, kind 3D spherical flower‐like structure was constructed by self‐assembly 2D nanosheets, Bi 2 S 3 particles with 5 ± 1 nm diameter were modified surfaces O CO nanosheets to prepare /Bi composite. energy level difference (0.45 eV) between conduction bands (CB) led which e − transferred CB .
