Abstract: There is provided a photocatalytic reactor including reaction chamber arranged to receive an airflow including one or more airborne contaminants. The reaction chamber includes a first inner surface, a second inner surface, a photo-catalyst for photocatalytic degradation of one or more of the contaminants disposed upon both the first inner surface and the second inner surface, and a light source arranged to illuminate at least a portion of the photo-catalyst disposed on the first inner surface and the second inner surface. The first inner surface and the second inner surface have distinct parabolic arc-shaped profiles and the profile of the first inner surface is a mirror image of the profile of the second inner surface. The first inner surface and the second inner surface may be consecutive.

Abstract: There is provided a photocatalytic reactor including a reaction chamber. The reaction chamber includes a first set of fins, a second set of fins, a photo-catalyst disposed upon at least one face of each fin, and a light source arranged to illuminate at least a portion of the photo-catalyst disposed on each fin. Each of the first set of fins is arranged such that a line extending from a base of the fin through a tip of the fin is directed to a first convergence point, and each of the second set of fins is arranged such that a line extending from a base of the fin through a tip of the fin is directed to a second convergence point. The first convergence point is different to the second convergence point, and both the first convergence point and the second convergence point are offset relative to a position of the light source.
