Dopamine molecules were oxidized and self-polymerized into nanofibers a template of lysozyme amyloid nanofibrils. The catechol groups adsorbed noble metal ions on the surface of the PDA nanofibers and reduced them into metallic nanoparticles with excellent catalytic activities. This study will not only pave a green way for fabricating 1D nanostructures biological templates, but also provide a unique opportunity for preparation and immobilization of noble metal nanocatalysts.
多巴胺分子被氧化并自聚合形成纳米纤维,成为溶菌酶淀粉样纤维纳米原纤维的模板。儿茶酚基团将贵金属离子吸附在 PDA 纳米纤维表面,并将其还原成具有优异催化活性的金属纳米粒子。本研究不仅为制备一维纳米结构生物模板开辟了一条绿色途径,而且为贵金属纳米催化剂的制备和固定提供了独特的机会。
