By developing graphene sponges with exceptionally high surface area and porosity, Professor Lee's team has achieved a remarkable 99% removal efficiency for a wide range of pollutants. This breakthrough not only improves water treatment performance but also enables scalable solutions for purifying large volumes of contaminated water. "Our work with 3D graphene composites is setting a new standard in wastewater treatment and offers a sustainable solution for purifying industrial and drinking water. Our innovative approach has gained international recognition, with the potential to be scaled across industries and countries” said Professor Lee. 

The implications of this research extend far beyond just improving water treatment systems. These 3D graphene composites are not only highly effective but also sustainable, with the ability to be regenerated for reuse, providing an environmentally friendly alternative to traditional purification methods.

Beyond water purification, Professor Lee’s research explores broader applications of graphene nanotechnology in environmental remediation. The graphene-based materials can be tailored to target specific pollutants such as lead ions, imipramine and azo dyes, making them highly adaptable to various contamination sources. The research also shows potential in addressing industrial chemical spills, hospital wastewater, and even soil condition and air pollution. 

From integration into industrial wastewater treatment plants to the development of portable water filters for rural and disaster-affected communities, this technology is on track to achieve real-world impact. By providing clean water through advanced nanotechnology, Professor Lee's research contributes to public health and supports the United Nations' Sustainable Development Goals (SDGs), particularly in clean water and climate action. 

With the potential to revolutionise water treatment, this research marks a significant scientific achievement and a vital contribution to a cleaner, healthier future.
