Title: Xuehong Gu: Innovator in Zeolite Membrane Technology

Introduction

Xuehong Gu is a prominent inventor based in Nanjing, China, known for his significant contributions to the field of zeolite membranes. With a total of five patents to his name, Gu has made remarkable advancements in the preparation methods of zeolite membranes, addressing critical challenges in the industry.

Latest Patents

One of Gu's latest patents is the "Preparation method of SSZ-13 zeolite membrane." This innovative method provides a solution to the issues of poor quality and excessive thickness commonly associated with SSZ-13 zeolite membranes. By utilizing a FAU-type zeolite as a raw material, Gu's method transforms it into an SSZ-13 zeolite with a particle size of 210 nm, achieving a mass yield of 91.2%. The resulting crystal seed exhibits a small particle size and thickness, enhancing the overall quality of the membrane.

Another notable patent is the "Method of preparing hierarchical porous channel molecular sieve membrane and application thereof." This invention outlines a process for creating a hierarchical porous zeolite membrane by incorporating a mesoporous structure-directing agent. This agent limits the growth of zeolite crystals, allowing for the self-assembly of a mesoporous structure during crystallization. The method enables one-step hydrothermal synthesis of the membrane, characterized by mild and controllable synthesis conditions, simplicity, good repeatability, reduced energy consumption, and cost savings. The hierarchical porous zeolite membrane produced through this method demonstrates excellent cut-off performance, with adjustable cut-off molecular weights ranging from 200 to 500,000 Da.
