Silicon quantum dots: A general photocatalyst for reduction, decomposition, and selective oxidation reactions
The 1-2 nm SiQDs can photocatalyze CO2 reduction and dye (methyl red) degradation, while 3-4 nm SiQDs can photocatalyze selective oxidation of benzene to phenol, owing to tunable band gap and excellent photoconductive properties of SiQDs.
