Waste-to-value: Spent coffee grounds derived Ni-decorated porous biochar for efficient plasma-catalytic ammonia synthesis

The shift from centralized Haber–Bosch to decentralized renewable ammonia synthesis demands catalysts with high activity and renewable compatibility. Here we report a Ni-decorated porous biochar catalyst (Ni/HBC-2) derived from spent coffee grounds. The optimized support (HBC-2)...
