Abstract Doping with pyridinic nitrogen atoms is known as an effective strategy to improve the activity of carbon-based catalysts for oxygen reduction reaction. However, prefer occupy at edge or defect sites carbon materials. Here, a framework named hydrogen-substituted graphdiyne provides suitable matrix doping. In graphdiyne, three in benzene ring are bonded hydrogen and serve active sites, like positions conventional materials, on which can be selectively doped. The as-synthesized...
Organic electrodes are potential alternatives to current inorganic electrode materials for lithium ion and sodium batteries powering portable wearable electronics, in terms of their mechanical flexibility, function tunability low cost.
