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 [...]
