CEE professor Baoxia Mi is developing a more efficient water filtration membrane constructed from graphene oxide, a carbon-based material that's made from naturally-occurring graphite, the same material found in pencils.

2021年1月21日 · In research published in the journal Nature Communications, a team of Brown University researchers has found a way to orient those gaps, called nanochannels, in a way that makes them more useful for filtering water and other liquids of nanoscale contaminants.

2021年12月1日 · Graphene-based nanofiltration membranes featuring distinct laminar structures can offer various novel mass-transport phenomena for purifying water, energy storage and separation, gas separation, and proton conductors.

2021年3月22日 · Increasing population and industrial growth, combined with climate change, led to global water problems. This review paper summarizes the next-generation hybrid graphene-based membrane materials that are used for water purification to meet global freshwater supplies.

2024年4月7日 · Graphene sheets (perforated with miniature holes) are studied as a method of water filtration, because they are able to let water molecules pass but block the passage of contaminants and substances.

2025年1月15日 · Würzburg chemists have succeeded in controlling the passage of halide ions by deliberately introducing defects into a two-layer nanographene system. Their results have been published in Nature. The...

2023年5月12日 · Here, we present a sustainable graphene-based water filter that can be regenerated by treatment with hot (80 °C) water or vinegar (mild acid). The filter has multiple desirable properties for heavy metal adsorption, including high surface area, conjugation, and oxygen-containing functional groups.

2023年1月22日 · Incorporation of nanoparticles like carbon nanotubes (CNTs) and metal oxide into the graphene filtering nanocomposite membrane structure can provide an improved photocatalysis process in a water treatment system.

2025年1月25日 · h Summary of the filtration performance of state-of-the-art membranes reported in the literature based on water permeances and rejection rates for heavy metal ions. Orange, green, and blue circles ...

2018年3月19日 · No other filtration method has come close to removing 99% of natural organic matter from water at low pressure,” Dr Joshi said. “Our results indicate that graphene-based membranes could be converted into an alternative new option that could in the future be retrofitted in conventional water treatment plants.”
