Abstract
A synergic effect of Rh and Ni in the bimetallic Rh(4)Ni nanocatalyst (Rh/Ni ratio = 4:1) makes it possible to achieve a 100% selectivity for hydrogen generation by complete decomposition of hydrous hydrazine at room temperature. The Rh(4)Ni nanocatalysts with a particle size of approximately 3 nm were prepared by alloying Rh and Ni using a coreduction process in the presence of hexadecyltrimethyl ammonium bromide (CTAB).
摘要
双金属 Rh(4)Ni 纳米催化剂（Rh/Ni 比=4:1）中 Rh 和 Ni 的协同作用使得在室温下通过水合联氨的完全分解来实现氢气生成的 100%选择性成为可能。通过在十六烷基三甲基溴化铵（CTAB）存在下使用共还原法合金化 Rh 和 Ni，制备出粒径约为 3nm 的 Rh(4)Ni 纳米催化剂。
