摘要： The present disclosure provides a honeycomb catalyst for catalytic oxidative degradation of VOCs prepared by an ultrasonic double-atomization process. The honeycomb catalyst is prepared by performing acidification and performing hydrothermal activation in alcoholic solution for honeycomb to modify a surface; dissolving soluble transition metal inorganic salt in deionized water to obtain precursor solution; performing ultrasonic atomization of the precursor solution and the precipitant solution in the ultrasonic atomization device into droplets; placing the modified honeycomb in a special quartz glass reactor, wherein the droplets enter into the quartz glass reactor through a pipeline to come into contact with a surface of a honeycomb hole and rapidly react to generate a hydroxide precursor on the surface of the honeycomb hole; drying the honeycomb into a drying box after performing the ultrasonic atomization, and calcining the honeycomb into a muffle furnace to obtain the honeycomb catalyst loaded with transition metal oxides.
