Embodiment Construction

[0031] Such as Figure 1-Figure 8 As shown, an in-situ electrochemical reaction cell for an electron paramagnetic resonance instrument includes an insulating tube 1, an L-shaped working electrode piece 2, an L-shaped auxiliary electrode piece 3, a pipe clamp joint 4, and a pipe cap.

[0032] The insulating tube 1 is a quartz glass tube, and the inner cavity of the insulating tube 1 is a rectangular reaction pool 101 . Moreover, the size of the insulating tube 1 matches the conventional resonant cavity 11 and can be placed in the resonant cavity 11 .

[0033] Rectangular reaction cell 101 is used to hold electrolyte, not only can increase the area allowed to be put into L-shaped working electrode sheet 2 and L-shaped auxiliary electrode sheet 3, but also can minimize the absorption of microwave by electrolyte solution during work. In addition, 101 Quartz material has good light transmission and can be used for the introduction of light radiation.

Abstract

The invention provides an in-situ electrochemical reaction tankfor an electron paramagnetic resonance instrument. Thereaction tank comprises an insulating tube, an L-shaped working electrode plate, an L-shaped auxiliary electrode plate and pipe hoop connectors. An inner cavity of the insulating tube is a rectangular reaction tank, the pipe hoop connectors are arranged at the two ends of the insulating tube, the vertical end of the L-shaped working electrode plate is inserted from an opening in the upper end of the rectangular reaction tank, the lower surface of the horizontal end of the L-shaped working electrode plate makes contact with the upper surfaces of the pipe hoop connectors, the vertical end of the L-shaped auxiliary electrode plate is inserted from an opening in the lower end of the rectangular reaction tank, the upper surface of the horizontal end of the L-shaped auxiliary electrode plate can make contact with the lower surfaces of the pipe hoop connectors, and a pipe cap is fixedly connected to the outside of the pipe hoop connectors and comprises an inner shell and an outer shell. A binding post is arranged on the inner shell, a first opening is formed in the inner shell, an electrolyte external interface is formed in the outer shell, and a second opening is formed in the outer shell. According to the reaction tank, in-situ electrochemical experiment online monitoring can be carried out, and the problem that electron paramagnetic resonance in-situ electrochemical online detection cannot be carried out is solved.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to an in-situ electrochemical reaction cell for an electron paramagnetic resonance instrument. Background technique [0002] Electron Paramagnetic Resonance (EPR) or Electron Spin Resonance (ESR) is an analytical technique used to study surfaces with high gyromagnetic ratio due to the presence of unpaired electrons or spin-orbits, with high sensitivity. Due to continuous improvement of instruments and continuous innovation of technology, electron paramagnetic resonance technology has been widely used in the fields of physics, chemistry, biology, medicine, environmental science, archaeology and material science. [0003] In-situ electrochemical electron paramagnetic resonance technology has always been the goal pursued by electrochemical workers, especially the EPR in-situ reaction cell for photoelectrochemical research, which is used to change the chemically modified elect...
