Recent Advances in Nanoporous Membranes for Water Purification

Nanoporous materials exhibit wide applications in the fields of electrocatalysis, nanodevice
fabrication, energy, and environmental science, as well as analytical science. In this review, we
present a summary of recent studies on nanoporous membranes for water purification application.
The types and fabrication strategies of various nanoporous membranes are first introduced, and
then the fabricated nanoporous membranes for removing various water pollutants, such as salt,
metallic ions, anions, nanoparticles, organic chemicals, and biological substrates, are demonstrated
and discussed. This work will be valuable for readers to understand the design and fabrication
of various nanoporous membranes, and their potential purification mechanisms towards different
water pollutants. In addition, it will be helpful for developing new nanoporous materials for quick,
economic, and high-performance water purification.
