Rational Design of Environmentally Friendly Carbon Nanotube Embedded Artificial Vesicle‐Structured Photocatalysts for Organic Pollutants Degradation

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(16)

Published: Jan. 2, 2024

Abstract Photocatalytic degradation is one of the most promising methods for addressing environmental issues without introducing pollution sources. Nonetheless, majority works are devoted to explore high‐efficiency semiconductor photocatalysts, but potential risks in their application usually neglected. In this work, an environmentally friendly vesicle‐structured photocatalyst rationally designed by employing magnetic layered double oxide‐hollow spheres@antimony tin oxide as a core, phospholipid membrane, and carbon nanotubes (CNTs) channels, yielding multi‐structural material with robust organic pollutants photocatalytic mineralization ability. Materials characterization, computational modeling, cytotoxicity tests suggest that under visible light irradiation, photogenerated charges can be rapidly generated transfer core composite, H 2 O effectively activated generate hydroxyl radical rapid degradation. The construction membranes embedded CNTs not only maintains photodegradation performance material, also restrains its risk. Such synthetic approach advances development bionic materials.
