The rotating disk electrode is a necessary instrument for electrochemical research, which has been widely used in the research and evaluation of hydrogen fuel cell catalysis, lithium-air battery research, oxygen reduction reaction research (ORR), oxygen precipitation reaction research (HER), carbon dioxide reduction reaction research (C02RR) and other fields. With the development of The Times, the rotating disk electrode technology is constantly innovative.
In 2024, the digital rotary disk electrode DSR developed by Wuhan DC New Energy shocked the market, causing industry concern.
Digital Speed Rotary DSR
What is the digital speed rotary disk electrode DSR, and how is it different from the current rotary disk electrode device in the laboratory? This article tells you.
At present, the rotary disk electrode device (RDE) uses the traditional analog signal control technology, although the analog signal cost is low, the technology is mature, but the analog signal has two shortcomings: poor anti-interference ability, large volume. Digital rotary disk electrode DSR adopts the advanced digital control chip technology, which effectively reduces the volume and improves the signal anti-interference ability. The digital rotary disk electrode device DSR is controlled by digital encoder electrode, and compares the actual value with the expected value by feedback, and compensates and adjusts the error to achieve accurate motion control. It can accurately control the position, speed and direction of the motor to achieve accurate control. The anti-interference ability of DSR digital signal technology ensures that the experiment is not interfered by environmental signal and noise, and the DC power supply mode of the host can reduce the interference of power clutter, so that the experimental data is more reliable.
Another feature of digital rotary disk electrode DSR is "quality", adhere to high standards of quality, excellent workmanship, there are 3 specific characteristics:
① The silver graphite carbon brush with silver content > 80% is configured to ensure that the electrical signal can be transmitted lossless, and the graphite ensures a good lubrication effect, which greatly improves the experimental stability and service life.
As we all know, the electrical conductivity of silver is relatively good, DSR uses a high silver graphite carbon brush to ensure that weak signals can be better transmitted.
② With a 15mm rotating rod, a stable dynamic reaction condition can be obtained.
The rotating rod is a very important part of the rotating disc electrode device, and the quality of the rotating rod directly affects the experimental data. The digital rotating disc electrode DSR rotating rod has the characteristics of "rod super collimation". Suitable for all kinds of electrolytic cell, easy to use with other instruments.
③ Rotating working electrode, μm precision manufacturing, accurate to ensure efficient collection rate and calculation of electron transfer number.
The manufacturing process quality of the working electrode is very important. DSR digital rotary disk working electrode adopts μm processing technology to ensure the experimental effect of users.
