This seems... cool but pretty pointless for indoor air purification. Maybe this is more like "passive purification". But an air purifier needs to turn over all the air in a room to purify it. My air purifier running at full speed takes half an hour to turn the air over in my room. Presumably this would never be capable of purifying a room to any sufficient level, it would just be a tiny 0.5% upgrade to a good active air purifier. Like having a desk plant. IMO I would drop the light concept, and put this thermocatalyst reactive material inside of a standard air purifier to replace the carbon filter. Unless this material isn't capable of handling a large workload, in which case... Ok
