High-density coordination unsaturated copper(i)–nitrogen embedded in graphene demonstrates a high performance and stability in primary zinc–air batteries with ultralow catalyst loading.
Rational design of high-perfomance bifunctional electrocatalysts to simultaneously accelerate the sluggish reversible oxygen reduction and evolution reactions (ORR and OER) is an enormous challenge that restricts the working efficiency and...
Hydrazine hydrate was employed to prevent Fe agglomeration and sulphate ions were used as the S source, which together led to Fe/N/S-CNTs with high performance.
