Check out this answer from Consensus:

The NH2 group is a versatile and essential functional group in chemistry, with applications ranging from catalysis and hydrogen storage to environmental remediation and combustion. Its unique properties and reactivity make it a valuable component in various scientific and industrial processes.

The chemical NH2, also known as the amine group, is a fundamental functional group in organic chemistry. It consists of a nitrogen atom bonded to two hydrogen atoms and is often found in various organic compounds, including amino acids, proteins, and many synthetic materials. This article explores the properties, applications, and significance of the NH2 group in different scientific contexts.

Properties of NH2

The NH2 group is characterized by its ability to act as a nucleophile due to the lone pair of electrons on the nitrogen atom. This makes it highly reactive and capable of forming bonds with various electrophiles. The presence of the NH2 group in a molecule can significantly influence its chemical behavior, including its acidity, basicity, and reactivity.

Applications in Catalysis

NH2-functionalized materials have shown great promise in catalysis. For instance, NH2-MIL-88B-Fe has been reported as an efficient catalyst for the electrochemical nitrogen reduction reaction (NRR) to produce ammonia (NH3) under ambient conditions. This material exhibits a high NH3 yield rate and Faradaic efficiency, making it a potential candidate for green ammonia production2.

Role in Hydrogen Storage

Inorganic imides containing the NH2 group are useful for hydrogen storage and base-catalyzed reactions. However, their instability under ambient conditions has been a significant challenge. Recent studies have demonstrated that NH2 can be incorporated into nanoporous crystals, enhancing their stability and making them viable for practical applications3.

Environmental Applications

NH2-functionalized metal-organic frameworks (MOFs) have been utilized for environmental remediation. For example, NH2-MIL-101(Fe) modified with quinone has been shown to effectively degrade bisphenol A (BPA) via persulfate activation. This modification enhances the catalytic performance and stability of the MOF, making it a promising material for environmental cleanup4.

Photocatalytic Applications

The NH2 group also plays a crucial role in photocatalysis. Titanium dioxide (TiO2) with surface oxygen vacancies has been used to photocatalytically convert nitrogen to ammonia in the presence of water. The NH2 group, in this case, facilitates the adsorption and reduction of nitrogen, leading to efficient ammonia production under mild conditions5.

Combustion Characteristics

The NH2 group is also significant in combustion chemistry. Co-firing NH3 with H2/CO/syngas has been studied to overcome the low reactivity of NH3/air flames. The addition of these gases accelerates NH3 decomposition and promotes the generation of H and NH2 radicals, enhancing the combustion characteristics of the flame6.
