N-doped semi-graphitic C loaded with metallic Co: synthesis parameters and catalytic selective reduction of p-nitrophenol

The N-doped semi-graphitic C loaded with metallic Co (Co/CN) could catalyze highly selective hydrogenation of p -nitrophenol (100% conversion) to p -aminophenol (98.5% selectivity). The magnetically separable catalyst was reusable for 14 cycles.
