Palladium/palladium oxide/calcium silicate/graphitic carbon nitride nanocomposite material

Abstract

A Pd@PdO/CaSiO3@g-C3N4 nanocomposite material includes spherical metal oxide nanoparticles, including a palladium@palladium oxide (Pd@PdO) phase and a calcium silicate (CaSiO3) phase dispersed on a matrix of graphitic carbon nitride (g-C3N4) nanosheets. The spherical metal oxide nanoparticles have an average particle diameter in a range from 25 to 250 nanometers (nm). The Pd@PdO/CaSiO3@g-C3N4 nanocomposite material has a Brunauer-Emmett-Teller (BET) surface area of at least 45 square meters per gram (m2·g−1). A method of preparing the nanocomposite material includes forming CaSiO3, g-C3N4, and Pd@PdO intermediates and combining in a microwave reaction to form the Pd@PdO/CaSiO3@g-C3N4 nanocomposite material.
