Description
Summary:[Display omitted] •A pentametallic (Au-Ti-Mg-Al-Cu) high-entropy mixed-dimensional mesoporous heterostructure.•HEMDMHs treat azo-dye wastewater degradation and decolorization at pH 2–12 at 0–60 °C.•Mesoporous LDH/MXene enhance physical absorption then AuNCs/LDH promote chemical degradation. The degradation and decolorization of azo-dyes wastewater require more efficient methodologies to reduce this primary water pollution source. Herein, we developed a pentametallic (Au-Ti-Mg-Al-Cu) high-entropy mixed-dimensional mesoporous heterostructure (HEMDMHs) for azo-dye wastewater degradation and decolorization. This HEMDMHs structure was constructed by irregularly growing nanoscale Mg-Al-Cu layered-double-hydroxide (LDH) onto micro-scaled 2-dimensional (2D) Ti3C2Tx MXene and then in-situ synthesizing ultrasmall (
