One of the major challenges for the widespread application of clean energy technologies like fuel cells and metal air batteries is the development of an efficient Pt-free electrocatalyst for the cathodic oxygen reduction reaction (ORR). Further, the ORR activity is largely dependent on the pH of the electrolyte. To use a single catalyst for anion exchange membrane fuel cell, cation exchange membrane fuel cells and direct methanol fuel cells, the catalyst should be ORR active in alkaline as well as in acidic media and should be methanol tolerant.In this regard, we synthesised chromium nitride (CrN) nanoparticles anchored onto N-doped graphitic carbon (CrN@NG) as a wide pH ORR catalyst active in alkaline as well as acidic media. The synthetic route offers a drastic development over traditionally used methods like nitridation, nanopatterning, etc by omitting the use of toxic ammonia and any expensive machinery. The CrN@NG catalyst is synthesized using simple precursors using single step pyrolysis. The CrN catalysts are reported to be used as ORR catalyst in alkaline media but the usage in acidic media is still restricted. Herein, the CrN@NG catalyst can potentially replacw Pt/C catalyst in alkaline and acidic media with comparable E1/2, Eonset and better durability. The close adherence of CrN nanoparticles and NG support plays a major role in enhancing the ORR activity. We believe that the simplistic method reported can be expanded to other metal nitrides as well.
