The invention discloses an in-situ monitoring method for reaction stability of a
titanium-containing multiphase
electrode in an
electrolysis process, and belongs to the field of electrochemical
metallurgy. On the basis of the closed gas sensor detection chamber, through gas circuit connection with the
molten salt electrolysis furnace, real-time in-situ monitoring of gas production components and concentration in the
electrolysis process is realized, so that the specific reaction condition is judged. And the
argon bottle, the pressure reducing valve, the flowmeter, the high-temperature
molten salt resistance furnace, the
water cooling device and the gas detection cabin are connected with the safety
bottle and the
tail gas
bottle through
polytetrafluoroethylene hoses. According to the method, the quantitative relation among the gas volume
signal, the electrolysis
overpotential and the
electrode surface area is established, the change of the
electrode surface area in the electrolysis process is calculated and analyzed in real time, the electrolysis
system is regulated and controlled by adjusting the electrode surface area, inputting the
current density and the like to recover stability, and the reason of the change of the electrolysis
overpotential is analyzed; and in-situ monitoring of the reaction stability of the
titanium-containing multiphase electrode in the electrolysis process is realized. The electrolysis environment is consistent with the commercial
titanium molten salt electrolysis environment.
