What is it about?

This is about using special materials called graphene-based nanomaterials to make filters for cleaning water. These materials have unique properties like being easy to modify, having tiny channels for water to pass through, being strong, and heating up when exposed to light. Scientists are combining these materials with other new ones and designing them in a certain way to make filters that clean water faster and better. This review has been showcased in the Nanoscale theme collection of Emerging Investigators by the Royal Society of Chemistry Publisher for the year 2023. This special theme issue recognizes the emerging talents in materials chemistry research for the year 2023 and compiles exceptional contributions from early-career materials chemists.
