    DescriptionA new type of versatile economical photocatalyst that harnesses the visible portion of the sunlight spectrum has been developed by researchers from the University of Johannesburg. It is simple to manufacture.

    Currently, economical photocatalysts only ‘use’ the UV spectrum of sunlight.

    The new photocatalyst harnesses about a third of the visible light spectrum.

    The extremely stable, powder-form three-component photocatalyst is built from graphitic carbon (89% of mass), a modified calixarene (10%) and a niobium-containing MXene (1%).

    Researchers at the University of Johannesburg have developed a new type of photocatalyst that harnesses the visible portion of the sunlight spectrum. Currently, economical and environmentally-friendly photocatalysts only ‘use’ the UV spectrum of sunlight, example the commonly-used titanium dioxide and other close equivalents.
