Pd3Bi intermetallic particles prepared by the photodeposition method for photocatalytic ethane production from methane

Abstract

A Pd₃Bi intermetallic compound (IMC) was photocatalytically deposited onto the gallium oxide (Ga₂O₃) surface at room temperature. Conventional impregnation and reduction methods were difficult for the formation of the Pd₃Bi IMC on Ga₂O₃, highlighting the importance of the photodeposition approach. The Pd₃Bi-loaded Ga₂O₃ photocatalyst exhibited 84% selectivity in methane-to-ethane conversion with hydrogen production in the presence of water vapour.
