According to the World Health Organisation (WHO), over 12% of all deaths are due to some form of exposure to air pollution , so removing these from our homes and cities is of the utmost importance. Current air purification systems are either unaffordable to those who need it or have inadequate performance - from issues such as expensive filters requiring replacement every few months, to ineffective removal of harmful contaminants.
A photocatalyst uses light to speed up certain chemical reactions, and even enable some to happen that wouldn’t be able to without it. The chemical reaction we are interested in is one that kills harmful organic things such as bacteria, viruses and gaseous pollutants (VOCs) in our air. The two main factors that affect the performance of a photocatalyst are the speed at which it degrades pollutants and how much it can absorb, so enhancing these properties is key.
There’s a special material called graphene, that when added to certain photocatalysts in the right way can drastically improve these factors. Anaphite is an anatase - Graphene nanocomposite produced via our patent pending process that has demonstrated over 2X more pollutant absorption and 3X times faster degradation when compared to anatase alone.
