Graphene Composite Improves Photocatalytic Activity Used to Degrade Pollutants

Facebook X LinkedIn Email
BERGAMO, Italy, Dec. 13, 2019 — Graphene Flagship partners developed a graphene-titania composite via a one-step procedure to widen and improve the applicability of “smog-eating” cement. The prepared composite showed enhanced photocatalytic activity, degrading up to 40% more pollutants than pristine titania in the model study, and up to 70% more pollutants in the case of nitrogen oxides (NOx). Organic pollutants, such as (NOx) and volatile compounds, are emitted mostly by vehicle exhausts and industry and are the primary cause of air pollution, the researchers said. The Graphene Flagship team working on...Read full article

    graphene
    Graphene is a two-dimensional allotrope of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice pattern. It is the basic building block of other carbon-based materials such as graphite, carbon nanotubes, and fullerenes (e.g., buckyballs). Graphene has garnered significant attention due to its remarkable properties, making it one of the most studied materials in the field of nanotechnology. Key properties of graphene include: Two-dimensional structure:...
