Introduction

Pingyu Wan is an inventor based in Beijing, China, associated with Beijing University of Chemical Technology. His work includes an invention for removing pollutants from contaminated water using a composite material that forms layered double hydroxide precipitates in situ.

Latest Patents

The supplied information lists 1 patent for Wan: “Composite Material and Method for Removing Pollutant from Polluted Water.” The invention uses a composite containing aluminum and at least one alkaline-earth or transition metal. As the material dissolves, it releases metal and hydroxide ions that interact with ions in contaminated water, forming two-dimensional layered double hydroxide precipitates.

The composite is described as containing 18–70 weight percent aluminum, 30–80 weight percent of a second metal, and 0–2 weight percent auxiliary agent, with particle sizes ranging from 0.01 to 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 soil remediation and sewage purification, including the removal or degradation of complex contaminants across acidic to alkaline conditions.

Career Highlights

Wan’s listed patent focuses on a material-based approach to environmental remediation. Its in situ formation of layered double hydroxides is designed to capture pollutants through interactions with ions in contaminated water.
