Carbon-based materials have been applied as cost-effective electrocatalysts to reduce carbon dioxide (CO2) into valuable chemicals. Here, an environment-friendly method is proposed to obtain nitrogen-doped porous carbons (NPCs) from digested sludge, which is an abundant waste product from sewage treatment plants. The materials were used as a metal-free electrocatalyst for electrochemical reduction of CO2 to formate. The synthesized material (NPC-60 had a mesoporous and microporous structure with a specific surface area of 246.21 m2
