Electrochemical nitrogen reduction reaction (NRR) provides a promising route for energy-effective and sustainable ammonia synthesis, while developing high-efficiency NRR electrocatalysts is extremely desirable. Here we first exploited foordite SnNb2O6 nanosheets...

The electrochemical N2 fixation using renewable electricity in water provides a renewable route for artificial NH3 synthesis, whereas developing active and selective catalysts is highly necessary for efficient N2 reduction...
