This paper reports the robust hydrothermal synthesis of N-CDs using the unripe fruit of peach as the carbon precursor and aqueous ammonia as the nitrogen source. The synthesized N-CDs exhibits a good catalytic activity in an alkaline medium (0.1M KOH) with remarkable ORR and highly biocompatible thu...
