Abstract: A preparation method of nitrogen-phosphorus doped porous carbon for oxygen reduction electrocatalysis within a wide pH range, which uses natural mineral-based carbon sources as raw material and uses a sequential nitrogen and phosphorus doping process for synthesizing in two paths. The method provided may be highly cost-effective, sustainable, and suitable for large-scale utilization.
