Preparation and Synergy of Supported Ru⁰ and Pd⁰ for Rapid Chlorate Reduction at pH 7.

ABSTRACT: Chlorate (ClO₃^-) is a common water pollutant due to its gigantic scale of production, wide applications in agriculture and industry, and formation as a toxic byproduct in various water treatment processes. This work reports on the facile preparation, mechanistic elucidation, and kinetic evaluation of a bimetallic catalyst for highly active ClO₃^- reduction into Cl^-. Under 1 atm H₂ and 20 °C, Pd^II and Ru^III were sequentially adsorbed and reduced on a powdered activated carbon support, affording Ru⁰-Pd⁰/C from scratch within only 20 min. The Pd⁰ particles significantly accelerated the reductive immobilization of Ru^III as >55% dispersed Ru⁰ outside Pd
