Abstract
Well supported: stable hemin-graphene conjugates formed by immobilization of monomeric hemin on graphene, showed excellent catalytic activity, more than 10 times better than that of the recently developed hemin-hydrogel system and 100 times better than that of unsupported hemin. The catalysts also showed excellent binding affinities and catalytic efficiencies approaching that of natural enzymes.
摘要
有充分证据支持
通过将单体血红素固定在石墨烯上形成的稳定血红素-石墨烯缀合物表现出优异的催化活性，比最近开发的血红素水凝胶体系高出 10 多倍，比无载体血红素高出 100 倍。这些催化剂还表现出优异的结合亲和力和接近天然酶的催化效率。
