Abstract

The invention discloses preparation and an application of a plasma gold / zinc oxide composite nanosheet array device. The preparation of the composite nanosheet array device is that gold nanoparticles are deposited on a zinc oxide nanorod array with an in-situ photodeposition method, and the morphology of the zinc oxide array is gradually converted into a nanosheet structure from a nanorod structure. The synthesized plasma gold / zinc oxide composite nanosheet array device is adopted for efficient photocatalytic reduction of carbon dioxide, illumination is carried out for 3 hours, and the yields of methane and ethane reach up to 95%. The preparation method of the device is simple, experimental conditions are easy to control, and the device is low in energy consumption, low in raw material price, suitable for large-batch production, very friendly to environment, high in carbon dioxide reduction rate under sunlight illumination, good in photocatalytic activity and stability and expectedly applied to actual production of solar fuel.

Description

technical field

[0001] The invention belongs to the field of preparation of photocatalytic device materials, and in particular relates to the preparation and application of a plasma gold / zinc oxide composite nanosheet array device. Background technique

[0002] As we all know, carbon dioxide is a greenhouse gas, and the increase in its emission is a key factor leading to global warming. Therefore, it is imminent to reduce carbon dioxide emissions and reduce the greenhouse effect by developing new clean energy or developing efficient carbon dioxide conversion and treatment technologies. At present, carbon dioxide fixation and conversion technologies include dissolution method, physical adsorption method, chemical absorption method, biological fixation method and membrane separation method, but these existing technologies generally have problems such as low efficiency and harsh reaction conditions. Compared with these technologies, the photocatalytic reduction technology has ...
