Photoreactor and application thereof

The invention provides a photoreactor and application thereof, and belongs to the technical field of light-driven reaction device design, the photoreactor comprises a light-transmitting window, a light reflection type curved surface inner cavity, a catalyst support and a gas path; the light reflection type curved surface inner cavity is arranged below the light inlet window; a closed reaction cavity is formed by the light-transmitting window sheet and the light reflection type curved surface inner cavity; the catalyst bracket is arranged in the reaction cavity; and the gas path is connected with the light reflection type curved surface inner cavity so as to be communicated with the reaction cavity. According to the photocatalytic reactor comprising the curve type reactor inner cavity light receiving surface, the light utilization rate is improved by changing a light path, the incident photon utilization rate is higher under the same light intensity condition, the catalytic effect is more excellent, meanwhile,
