Size Control of Ni Nanocluster by the Carbon Chain Length of Secondary Alkoxide

Abstract

Secondary-alkoxide stabilized Ni colloid was synthesized using secondary alkoxide as a reducing and stabilizing agents. Cluster size was controlled by changing carbon chain length of secondary alkoxide; 2-octanol derived alkoxide gave the smallest nanocluster. Ni colloid thus prepared was applied to the preparation of supported Ni nanocluster catalysts. Size dependency of Ni nanocluster on catalytic activity for water gas shift reaction was observed.
