A one-pot synthesis of a monolithic CuO/Cu catalyst for efficient ozone decomposition.

Nowadays, it is necessary and challenging to prepare monolithic catalysts, which are ready for use, preventing the tedious and complicated integration procedure of the powder materials onto a porous substrate. Herein, CuO nanoparticles are successfully synthesized onto a porous Cu foam in one pot the surface oxidation, coordination and precipitation reactions in a NHOH and HCl solution, and the optimum synthesis conditions are a NH : HCl ratio of 1 : 0.9, oxidation temperature of 80 °C and time of 18 h.
