Abstract
The catalytic properties of cadmium sulfide nanoparticles in the photochemical decomposition of hydrogen peroxide are studied. It is shown that in aqueous H2O2 solutions of any concentration, cadmium sulfide accelerates the reaction and does not change its order. The quantum yield of the reaction is 1 and does not depend on the concentration of hydrogen peroxide. The scattering of light by particles and an increase in their concentration reduces the quantum yield.
