Electrocatalyst based on nano niobium dioxide for nitrogen reduction

Ammonia is the largest chemical product produced on earth, with an annual production of more than 150 million tons, and has been synthesized by the Haber-Bosch process for more than 100 years. However, the Haber-Bosch process uses hydrogen derived from natural gas reforming to reduce nitrogen under high temperature and pressure, so it is a process with high energy consumption and CO2 emission. However, the electrochemical nitrogen reduction reaction (NRR), which directly uses water and nitrogen as raw materials [...]

Introduction to the properties and applications of nano boron nitride (BN)

Boron nitride, chemical formula BN, a non-oxide material, is the isoelectronic body of carbon (C2), its crystal structure is similar to graphite, is currently one of the more studied and applied nitride ceramic materials. According to the crystal structure type, BN mainly includes hexagonal boron nitride (H-BN), cubic boron nitride (C-BN), rhombic boron nitride (R-BN), wurtzite boron nitride (W-BN). What are the properties of boron nitride? As a structural analogue of graphite, BN has better physical and chemical properties than [...]
