Efficient electrosynthesis of high-purity carbon monoxide...
A research group has developed a new method for extracting high-purity carbon monoxide. High-purity carbon monoxide (CO) is a key raw material in the chemical industry, widely used in the preparation of phosgene and metal carbonyl compounds. Currently, CO production still relies primarily on fossil fuels and involves energy-int...

The gas properties of helium
Helium is a colorless, odorless and inert gas with completely inactive chemical properties. In industry, helium is mainly separated and refined from natural gas rich in helium to produce high-purity helium, which is then liquefied into liquid helium and transported to various parts of the world to be filled into helium cylinders. &nbs...

Correct way to use sf6 sulfur hexafluoride gas
Sulfur hexafluoride (SF6) is an inert gas with high stability at room temperature and pressure. It is colorless, tasteless, odorless, non-toxic, and non-flammable. Due to its excellent insulation and arc-extinguishing properties, it has been successfully used in high-voltage electrical equipment since the 1960s, ushering in a major re...

Precautions for the application of high-purity xenon in a...
The principle behind automotive high-voltage xenon lamps is to use a booster to instantly boost the vehicle’s 12V DC voltage to 23,000V. This then creates a bipolar arc, without the need for a tungsten filament, and the high-voltage amplitude excites xenon electrons within the crystal glass tube, generating a bright, daylight-li...

What is xenon gas? Precautions for storing and transporti...
1. What is Xenon Gas? Xenon (Xe) is a colorless, odorless, tasteless noble gas (Group 18). Naturally inert, it exists in trace amounts in Earth’s atmosphere (~0.087 ppm). Discovered in 1898 by Ramsay and Travers at UCL during liquid air fractionation, it produces distinctive blue light when electrified. Its extreme rarity is a prima...

When will sulfur hexafluoride gas be replaced?
Due to the greenhouse effect, the use of sulfur hexafluoride (SF6) is subject to significant restrictions. SF6 has a global warming potential (GWP) 23,900 times that of CO2 and a lifetime in the atmosphere of 3,400 years. The atmospheric concentration of SF6 has been increasing at an annual rate of 8.7%, now accounting for over 15% of...
