Abstract
Herein, we synthesized a hydrophilic support formed from amorphous CrO and KIT-6 containing P123 using a simple solvent-free thermal method for Co species. The obtained catalyst (denoted as Co/CrO-F-) exhibits high activity for hydrogen production from ammonia borane (NHBH). The optimal Co/CrO-F-0.5 exhibits the highest catalytic performance with the turnover frequency (TOF) value of 111.1 min. Advanced characterizations suggest the high catalytic performance is attributed to the synergistic effect of the strong interaction between amorphous CrO and KIT-6 containing P123 and improved wettability of the catalyst.
摘要
在此，我们采用一种简单的无溶剂热法，为钴物种合成了一种由非晶态CrO和含P123的KIT-6形成的亲水性载体。所制备的催化剂（记为Co/CrO-F-）对氨硼烷（NHBH）产氢表现出高活性。最优的Co/CrO-F-0.5展现出最高的催化性能，其周转频率（TOF）值为111.1 min⁻¹。先进的表征表明，高催化性能归因于非晶态CrO与含P123的KIT-6之间强相互作用的协同效应以及催化剂润湿性的改善。
