Abstract
There is disclosed a method of constructing a layered double hydroxide (LDH) material comprising selected metal ions, and employing metallic vanadium carbide (V2C) for promoting conductive properties of the LDH material, wherein the layered LDH material is a trimetallic LDH material. The trimetallic LDH material comprises selected Ni2+, Co2+, and A3+ metal ions with its cationic configuration for improving photocatalytic properties of the LDH material, wherein trimetallic nickel-cobalt-aluminium layered double hydroxide (NixCoyAlz LDH) and vanadium carbide MXene (V2C)-based composite is coupled with a graphitic carbon nitride (g-C3N4) nanosheet, to form a hybrid-junction photocatalyst. Also disclosed is a layered structure of vanadium carbide (V2C) MXenes, comprising trimetallic nickel-cobalt-aluminium layered double hydroxide (NixCoyAlz LDH) and vanadium carbide MXene (V2C) coupled with graphitic carbon nitride (g-C3N4), forming a NixCoyAlz LDH/g-C3N4 hybrid-junction photocatalyst.
