Controllable Synthesis of Bimetallic Cupd Micro-Rods for Catalyzing Hydrogenation of 4-Nitrophenol

Abstract

The fabrication of the efficient catalyst for the hydrogenation of 4-nitrophenol is of major significance for both environment protecting and industrial resource. Here, bimetallic CuPd micro-nano structures with string, rod, polyhedron can be fabricated by using the nicotinic acid. The optimization of synthesis was investigated by modulating the ratio of precursors and reaction conditions, and the correlation between catalytic properties and morphology of materials was also estimated. Among them, CuPd micro rods synthesized by 0.2 M nicotinic acid exhibited the highest catalytic activity in the hydrogenation reaction of 4-NP by sodium borohydride. The evaluation of reusability demonstrated the catalytic efficiency maintained the conversion yield of 98% without significant loss of performance. The synergistic effect of bimetallic catalyst promoted efficient performance in the hydrogenation, which will arouse the extensive development of bimetallic catalyst and serve in the catalysis efficiently.
