Photoelectrocatalytic carbon dioxide reduction reaction analysis and detection system and its application method

Abstract

The invention discloses a photoelectrocatalysis carbon dioxide reduction reaction analysis and detection system and a use method thereof. The photoelectrocatalysis carbon dioxide reduction reaction analysis and detection system comprises a photoelectrocatalysis carbon dioxide reduction reaction device, a carbon dioxide supplying device and a gas quantitative analysis and detection system; a reactor main body consists of two semi-reactors; one semi-reactor is provided with a lighting window, and a sealing sheet is arranged at the window; the two semi-reactors are mutually connected and fixed through a clamping device; air inlets and air outlets are respectively formed in two ends of rotating covers, the rotating covers are connected and sealed with the reactor main body through threads, electrode copper pillars are arranged on the rotating covers and are used for respectively providing bias voltage to a working electrode, a counter electrode and a reference electrode, and a liquid phase sampling hole is formed in each rotating cover. Light can be applied to a semiconductor catalytic material through the lighting window, so as to achieve a photoelectrocatalysis process, and a product is quantitatively analyzed by virtue of the gas quantitative analysis and detection system. The photoelectrocatalysis carbon dioxide reduction reaction analysis and detection system is simple in structure, smart in size and convenient to implement and can be used for rapidly and accurately carrying out the gas quantitative analysis and detection.

Description

technical field [0001] The invention belongs to the technical field of illumination and electrolytic reaction and the technical field of photoelectrochemical reaction product analysis and detection, and in particular relates to a photoelectric catalytic carbon dioxide reduction reaction analysis and detection system and a use method thereof. 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-ene...
