摘要：
MnO2 is a promising catalyst for oxygen reduction and metal-air batteries due to the natural abundance, low cost and nontoxicity. Improving its activity is an important challenge for its large-scale commercialization. Defect engineering and heteroatom doping are the most effective means and can be easily operated through plasma treatment at different atmospheres. In this work, defects on MnO2 are manufactured via rapid plasma treatment at Ar atmosphere while both defects and N-doping are simultaneously fabricated at N-2 atmosphere. N-MnO2 exhibits a greatly enhanced ORR activity with a half-wa...
