Synthesis of a Pd on Ni–B nanoparticle catalyst by the replacement reaction method for hydrodechlorination

---

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 obtained by the replacement reaction of
nanocrystalline Ni with Pd2+ ions. The properties of the Pd/Ni–B catalyst were studied in detail by XRD,
TEM, XPS, and H2 chemisorptions. The characterizations demonstrated that a Pd–Ni–B surface alloy occurred
on the Pd/Ni–B catalyst with heating treatment. The resulting surface alloy promoted resistance
to chlorine poisoning, adsorption of the reactants (chlorobenzene and hydrogen), and desorption of products,
explaining the better catalytic activity and stability of the Pd/Ni–B bimetallic catalyst.
