Abstract:
1. An ultraviolet transparent (UVT) biopolymer photocatalytic system comprising: an ultraviolet transparent (UVT) biopolymer photocatalytic structure; and a UV source: wherein the structure comprises a UVT biopolymer layer, comprising polylactic acid and having a surface; and a nanophotocatalytic layer arranged on the surface of the UVT biopolymer layer; and wherein the structure is arranged and oriented relative to the UV source such that light in a UV spectra from the UV source reaches the UVT biopolymer layer, passes through the UVT biopolymer layer, and activates the nanophotocatalytic layer.
