Texas A&M: Black Phosphorous Research in Pollution Remediation Show Promise as a Safe, Effective Method

Dr. Virender Sharma, at the Texas A&M School of Public Health, and others investigated research on environmental decontamination using black phosphorous (BP). Their study, published in the Chemical Engineering Journal, reviewed the studies of BP-based nanomaterials in decontamination of water and air as well as research on improving BP’s stability and possible future uses of these materials.

One study examined the use of a single layer BP composite to remove arsenic and chromium from water, which was highly effective. Another study looked at removing dioxin from polluted water, and noted that BP doped with calcium atom performed well. Another study compared the performance of a BP-based composite against that of metal oxides and graphene at removing organic dyes and found that BP performed better.

BP is a promising material for cleaning polluted water and for decontaminating air. A study found that BP composites treated with platinum, aluminum and nickel were most effective at trapping toxic gases on their surfaces.

One study found that BP-based materials perform extremely well at removing dyes from water under ultraviolet light and treating BP with titanium dioxide made the material much more stable.

Other studies looked at improving BP’s photocatalytic performance by combining it with materials like silver nanoparticles and found that the resulting materials were well-suited for eliminating organic pollutants like BPA from water. Studies of BP’s photocatalytic abilities in the air found that BP-based materials could eliminate nitric oxide from the air, oxidizing it into less harmful compounds, and that the materials were stable for a long time.

The researchers also found several studies focusing on the ways to address BP’s deterioration in water or humid air and thus improve its stability.
