## Abstract

An air sanitation and purification photocatalytic panel includes a frame that has a photocatalytic scrim positioned within the frame and a plurality of UV light sources positioned within the frame proximate to the photocatalytic scrim. The frame is made of a metal and/or alloy. The photocatalytic scrim is a pleated structure. Each of the plurality of UV light sources are oriented towards the photocatalytic scrim. The photocatalytic scrim includes a substrate a photocatalytic coating adhered to the substrate. The frame and photocatalytic scrim are oriented parallel to each other. The UV light sources illuminate the photocatalytic coating and initiate a photocatalytic reaction therein. During operation, the panel is positioned perpendicular to the airstream such that the airstream is forced through the substrate.

## Claims

### Claim 1

A photocatalytic panel comprising:
a frame;
a photocatalytic scrim;
the photocatalytic scrim being positioned within the frame;
a plurality of UV light sources;
the plurality of UV light sources being positioned within the frame;
the plurality of UV light sources being proximate to the photocatalytic scrim;
an arbitrary UV light source among the plurality of UV light sources being positioned about 6 inches from an adjacent UV light source among the plurality of UV light sources;
the frame comprising a metal and/or an alloy;
the photocatalytic scrim being a pleated structure;
each of the plurality of UV light sources being oriented towards the photocatalytic scrim;
the photocatalytic scrim comprising a substrate and a photocatalytic coating;
the photocatalytic coating being adhered to the substrate;
the photocatalytic coating comprising a thickness of 10 nm to 9.8×104 nm;
the frame and the photocatalytic scrim are oriented parallel to each other;
the plurality of UV light sources initiating a photocatalytic reaction with the photocatalytic coating; and
the photocatalytic panel being configured to be positioned perpendicular to an airstream such that the airstream is forced through the substrate.

### Claim 2 (depends on 1)
