Introduction

Xiaojin Yang is an inventor based in Beijing, China, associated with Beijing University of Chemical Technology. His work includes an invention designed to remove pollutants from contaminated water through the formation of layered double hydroxide precipitates.

Latest Patents

Yang is associated with 1 patent: “Composite Material and Method for Removing Pollutant from Polluted Water.” The invention describes an aluminum-alloy composite containing aluminum and one or more alkaline-earth or transition metals. When the material dissolves in polluted water, it releases metal and hydroxide ions that interact with ions in the water, promoting the in situ formation of layered double hydroxides.

The composite is specified to contain 18–70 weight percent aluminum, 30–80 weight percent of a second metal, and 0–2 weight percent auxiliary agent, with a particle size of 0.01–3 millimeters. Pretreatment with dilute hydrochloric acid can produce a micro-nano Alloy@LDH composite with a core-shell structure. The invention is intended for sewage purification and soil remediation, including the removal or degradation of complex contaminants across acidic to alkaline conditions.
