                 Figure 1: Rationale               

 

Electrochemical in situ infrared spectroscopy analysis is an important branch of infrared analysis technology capable of qualitative analysis of electrocatalytics (infrared spectral analysis) The changing trends in electrodes surfaces or intermediates during charging of batteries (e.g. lithium ion, lithium sulphur batteries, etc.) such as CO2 reduction are one of the important means of studying electrochemical reaction mechanisms and electrochemical reaction dynamics.

I. Rationale:

 

Internal reflection mode:

(1)Chemical plating or vacuum plating of a nanogold membrane on a single crystal silicon (Si) has surface enhancement effects.

(2)Nano-finum membrane can be used as a conductor base, as a catalyst for dripping on the conductor base or for electrode deposition as a working electrode.

(3)Surface enhancement provides information on electro-catalyst adsorbent products and intermediate products.

 Figure 2: Fundamentals of the internal reflection model

External reflection mode:

(1)On the surface of substrate electrode (e.g. GCE), electrode deposition or dripping catalysts are used as working electrodes.

(2)The distance of the working electrodes from the crystal can be adjusted.

(3)Crystal option Ge, ZnSe, CaF2Si and so on.

Composition of the Annex:

(1)Infrared spectrometer (IR spectrometer) hosts fit the base plate and fit the mainstream infrared spectrometer.

(2)A plane mirror with a curved mirror.

(3)Injection angle adjustment system.

(4)Declining full-reflective crystals.

(5)Glass electrochemical pool (single or H-type pool) and an external reflector pool for PEEK.

(6)Electrodes (carbon electrodes, electrodes, reference electrodes).

(7)Distance reconciliation system.

 

III. Main features:

(1)Moable into angular optics, 30-80 degrees continuous to ensure maximum light flux for different electron catalysts.

(2)The decay of a full reflection crystal has an enhanced permeable membrane that increases light flux by more than 10 per cent.

(3)The electrochemistry pool is in good condition to be sealed and accessible to reaction gases.

(4)Crystal disassembly is simple and allows for grinding.

(5)Options for crystal types such as Si, Caf2ZnSe etc.

(6)Electrochemical single or H-type pools, toggle convenient.

(7)Provide on-site technical services.

(7)Reaction pool customized to client needs and feasibility options provided。
