QUANTUM DOT COMPOSITE PHOTOCATALYST

摘要

PROBLEM TO BE SOLVED: To provide a high reaction efficiency photocatalyst using a quantum dot.SOLUTION: Provided is a quantum dot composite photocatalyst for spatially charge separating the excitation electron and hole generated by light irradiation, and reducing the recombination probability of the exciton, and in which a quantum dot having a particle diameter of 0.7 nm to 3.0 nm and made of a transition metal oxide, and any one of a second quantum dot made of a different kind transition metal oxide from the quantum dot, an organic compound, or a zero-valent metal dot are complexed.SELECTED DRAWING: Figure 3
