Synthesis of a Pd on Ni–B nanoparticle catalyst by the replacement reaction…

Abstract. A Pd on Ni–B (Pd/Ni–B) bimetallic nanoparticle catalyst was prepared through a replacement reaction of amorphous Ni–B nanoparticles with Pd2+ ions. In the hydrodechlorination of chlorobenzene, the Pd/Ni–B bimetallic catalyst exhibited better activity than a Pd catalyst supported on polyvinylpolypyrrolidone, a mixture of Pd and Ni–B nanoparticles, and a Pd on Ni catalyst …
