What is hydrogen?


Hydrogen is a simple element in nature, hydrogen is a colorless, odorless, tasteless, reductive diatomic gas. Hydrogen, which makes up about 90 percent of the universe, is arguably the most basic chemical element in the universe. Similar to oxygen and nitrogen, hydrogen has a relatively low solubility, but oxygen can combine with hemoglobin and can be absorbed by the body through respiration, while hydrogen and nitrogen cannot be absorbed in large quantities. People have not paid attention to the role of hydrogen in higher organisms.

What is a hydrogen sensor?


Hydrogen sensor is very sensitive to hydrogen at room temperature and has good selectivity, which can be used as a sensor to detect hydrogen concentration in the environment. Due to the safety requirements in production and life, fast, sensitive and accurate hydrogen sensor is very necessary to avoid the possibility of explosion in time.

What does hydrogen do?


1. In the petrochemical industry, hydrogenation is required to refine crude oil through desulfurization and hydrogenation cracking.

2. Another important use of hydrogen is to hydrogenate fats in margarine, cooking oil, shampoo, lubricants, household cleaners and other products.

3. In the high-temperature processing of glass manufacturing and the manufacture of electronic microchips, hydrogen is added to the nitrogen gas to remove residual oxygen.

4, used as raw materials for synthesis of ammonia, methanol and hydrochloric acid, reducing agent for metallurgy.

5. The space industry uses liquid hydrogen as fuel due to its high fuel nature.
