Abstract:
1. A method for preparing a metal-treated particle, comprising: providing a plurality of cores having an average largest transverse dimension of from about 5 nanometers to about 1100 nanometers, at least one metal-supplying agent and an alkali metal hydride reductant capable of reducing the metal-supplying agent; contacting the at least one metal-supplying agent and the reductant in the presence of the cores to form at least one metal-treated particle by chemical reduction of the metal-supplying agent to deposit the metal on surfaces of the cores; and recovering the at least one metal-treated particle, wherein a total amount of metal in each metal-treated particle is from about 8% to about 22% by weight based on a total weight of each metal-treated particle and a surface area of the at least one metal-treated particle is from about 35 m
