Description

technical field [0001] The invention belongs to the technical field of air disinfection devices, and in particular relates to an ultrasonic-assisted nano-photocatalytic air sterilization and purification device. Background technique [0002] The harmfulness of indoor air pollution has been recognized by the whole society. Nanophotocatalysis is considered to be one of the most promising air purification technologies. However, the photocatalytic quantum efficiency of nanophotocatalysts that can be obtained at present is still very low, and photocatalysis is a typical surface catalytic reaction, that is, only when pollutants are in close contact with nanophotocatalysts can they exert their excellent catalytic properties. Because of these two points, the effective development and application of the current nano-photocatalytic air purification technology has been affected. Using multi-field energy (electric field, magnetic field, microwave, low-temperature plasma and ultrasonic...
