Abstract

An experimental apparatus for a photoelectrocatalysis reaction is connected to an electrochemical system and a gas chromatograph at the same time, so that when a to-be-treated gas is treated through a photoelectric reaction, a photocurrent and a gaseous product generated from the photoelectric reaction can be detected at the same time. The experimental apparatus is characterized by comprising a reaction part having a chamber and a sealing cover, both of which are made from a quartz material; an air intake part arranged on the chamber, communicating with the chamber and used for leading the to-be-treated gas to the inside of the chamber for a reaction; an air discharge part arranged on and communicated with the chamber for leading the gaseous product out of the chamber to the gas chromatograph for detection; and an electrode port part comprising a reference electrode port, a counter electrode port and a working electrode port, which are located on the side wall of the chamber in three directions, wherein the reference electrode port is arranged relative to the counter electrode port and the reference electrode port, the counter electrode port and the working electrode port are provided with a reference electrode column, a counter electrode column and a working electrode column, respectively, which are connected to the electrochemical system.

Description

Technical field [0001] The invention relates to a photoelectric catalytic reaction experimental device, in particular to a multi-functional and novel photoelectric catalytic reaction experimental device. Background technique [0002] As a commonly used measuring device for electrochemical research and teaching, the electrochemical workstation has a digital signal generator, data acquisition system, multi-level signal gain, potential current signal filter, IR drop compensation circuit, galvanostat, and potentiostat. It can complete the measurement and control of certain electrochemical parameters under different conditions, and is extremely widely used in electrochemical measurement. In addition to the quantitative and qualitative analysis of the components in the mixed gas, the gas chromatograph can also determine the physical and chemical constants such as the distribution coefficient, activity coefficient, molecular weight and specific surface area of ​​the sample on the statio...
