SEM images of monolithic catalysts prepared (a) using a slurry of co-precipitated Co/CeO2 (b) using CeO2 washcoating followed by Co impregnation [51]; (c) CO conversion obtained with the monolithic catalysts [51]; (d) UV-vis spectra for AuCu/CeO2 ceramic monolithic catalysts [43]; (e) influence of the modified dip coating method on coating adhesion [52]; (f) CO conversion at different space velocities for CuO/CeO2 ceramic monolithic catalysts via the urea–combustion method [53].
