Embodiment 1

[0019] figure 1 It is a structural schematic diagram of the present invention, as shown in the figure, an electrochemical reaction cell that can be used for dark field microscopic observation, including an electrochemical reaction cell and an electrochemical element, wherein the electrochemical reaction cell is made of ITO glass An insulating thin layer-2 with holes is installed on the sheet 1, and the holes on the insulating thin layer-2 are two and the two holes are connected; the electrochemical element includes a counter electrode 3 and a reference electrode 4, and the counter electrode 3 and the reference electrode 4 are respectively positioned and installed in the holes on the insulating thin layer-2. The hole on the insulating thin layer is the space for receiving the sample. Further, the insulating thin layer-2 is a polydimethylsiloxane thin layer, or other materials such as non-conductive high polymers. Since the insulating thin layer is very thin, low-height operat...

Embodiment 2

[0024] This example illustrates the fabrication of the device.

[0025] Preparation of PDMS thin-layer cover sheet: Sylgard184 monomer and curing agent are mixed in a ratio of 10:1 (mass ratio), degassed, poured on a clean plane cofferdam, heat-cured, and then peeled off to obtain it. Hole punching.

[0026] Design and manufacture PDMS (polydimethylsiloxane) film; cover the cured PDMS with a round hole on the ITO glass treated by plasma; adhere the PDMS thin layer with three notched holes to the above On the PDMS thin layer, the first notch hole of this layer is aligned with the hole on the PDMS thin layer of the first layer. The reaction cell was then fixed under a dark-field microscope.

[0027] After the glass and PDMS were cleaned separately, they were placed in a plasma cleaner for 2 minutes, and then aligned and bonded immediately.

[0028] Preparation of the electrode positioning device: spirally coil the bottom ends of the counter electrode and the reference electro...

Description

technical field [0001] The invention belongs to the technical field of electrochemistry and relates to an electrochemical reaction cell which can be used for dark-field microscopic observation. Background technique [0002] With the development of modern science and technology, optical microscopic technology and spectral technology have been applied to more and more extensive scientific and technological fields and production departments through continuous improvement and development. Single particle spectroscopy is a traditional spectral research method based on microscopic imaging technology. Combining spectral microscopy with TEM, SEM, STM, Atomic Force Microscope (AFM), and electrochemistry has become one of the simplest and most convenient methods for studying nano-metal colloids. Currently published electrochemical reactors that can be used under dark-field microscopes often have problems such as inconvenient operation, poor reusability, complex device integration, an...
