Abstract

The invention provides a photoelectric-catalytic carbon dioxide reduction device and an application thereof. A reactor main body comprises two half-reactor main bodies of which one half-reactor main body is provided with an illumination window, wherein a sealing sheet is arranged at the window and two half-reactors are fixedly connected through a clamping device. A gas inlet and a gas outlet are respectively formed in both ends of a rotary cover, the rotary cover is hermetically connected with the reactor main body through a thread, electrode copper cylinders for respectively providing a bias for a working electrode, a counter electrode and a reference electrode are arranged on the rotary cover and a liquid phase sampling hole is formed in the rotary cover. Illumination can be applied to a semiconductor catalytic material by virtue of the illumination window so as to achieve the photoelectric-catalytic carbon dioxide reduction process. The photoelectric-catalytic carbon dioxide reduction device is simple in structure and convenient to implement, has compact size and can be conveniently connected with a gas detection system so as to quickly and accurately carry out quantitative analysis and detection on gas.

Description

technical field [0001] The invention belongs to the technical field of illumination and electrolytic reaction, specifically relates to the technical field of photoelectrochemical reactor, and more specifically relates to a photoelectric catalytic carbon dioxide reduction reaction device. Background technique [0002] In recent years, with the rapid economic development and the rapid consumption of resources and energy, CO in the atmosphere 2 The concentration of the main greenhouse gas continues to increase, how to stably control the CO in the atmosphere 2 Gas concentration quickly became a research hotspot. In nature, photosynthesis of plants is ubiquitous. From an energy point of view, green plants use sunlight to convert CO in the atmosphere 2 converted into organic matter such as sugars, and at the same time convert and store solar energy into chemical energy, which is very important for the development of low-energy CO 2 Transforming and leveraging technology is som...
