Covalent bonds between different elements make the compounds nanoparticles have specific properties and composition, and make the entire system more stable. Compounds nanoparticles have unique mechanical properties, contact reaction activity, optical properties, electrical conductivity and other characteristics due to their nanometer particle size, and have gradually been widely used in
