Creation of Pd/Al₂O₃ Catalyst by a Spray Process for Fixed Bed Reactors and Its Effective Removal of Aqueous Bromate.

ABSTRACT: Palladium nanoparticles were grown on sub-millimeter activated Al₂O₃ particle support by spraying H₂PdCl₄ solution evenly onto the support, followed with a thermal reduction under H₂ atmosphere. Compared with its counterpart created by the conventional impregnation method, the Pd/Al₂O₃ catalyst created by the spray process could enrich the existence of active Pd nanoparticles on the surface of the catalyst support and increase their degree of dispersion, resulting in a much higher activity in the catalytic reduction of bromate in water. The effect of Al₂O₃ support particle size on the bromate removal rate was also investigated, which demonstrated that smaller support particle size could have
