Gold was loaded onto porous nanocomposite of ZrO 2 and silicate by deposition–precipitation. The resulting Au/ZrO 2 -nanocomposites are found to be superior catalysts for removal of formaldehyde from indoor air at moderate temperature by oxidation. They have large specific surface areas and allow the gold to be adequately dispersed as small nanoparticles (NPs). According to the analysis...
