Tremendous attention has been focused on exploring highly efficient and economical catalysts to the reduction of p-nitrophenol for the purpose of green chemistry. However, it is still a challenge to elevate the catalysts with high activity and desirable recyclability. Herein, Cobalt-Cobalt Ferrite (Co-CoFeO) nanobrushes have been synthesized by controlled growth-reduction process in one step, which is applied to catalyze the reduction of p-nitrophenol. In situ generated active Co(0) can induce Co-CoFeO nanobrushes to achieve higher catalytic activity with a reaction rate of 0.0457 s for the reduction of p-nitrophenol due to the synergetic effect between in situ generated Co(0) and its induced defects on the CoFeO support. Compared with other catalysts calculated and gathered in Table S1 in Supporting Information, as-designed Co-CoFeO nanobrushes can be employed as a good candidate for the nitro-reduction reaction.
人们高度关注探索高效、经济的催化剂以实现绿色化学中对 p-硝基苯酚的还原。然而，提高具有高活性和理想可回收性的催化剂仍然是一个挑战。在此，通过一步控制生长还原过程合成了钴-钴铁氧体（Co-CoFeO）纳米刷，将其用于催化 p-硝基苯酚的还原。原位生成的活性 Co(0)可以诱导 Co-CoFeO 纳米刷实现更高的催化活性，p-硝基苯酚的还原反应速率为 0.0457 s，这是由于原位生成的 Co(0)与其在 CoFeO 载体上诱导的缺陷之间的协同效应。与支持信息中的表 S1 中计算和收集的其他催化剂相比，设计的 Co-CoFeO 纳米刷可用作硝基还原反应的良好候选物。
