Regarding how efficient photo-oxidative catalytic waste gas treatment equipment really is

I recently encountered an environmental inspection that indicated a low photocatalytic oxidation efficiency. I was wondering if others have faced this issue as well; what is the efficiency level for those who have installed photocatalytic oxidation systems and had them tested?
Although many claim an efficiency of 70-80%, in reality it can only reach around 30-40%; in some cases, if issues such as design are not properly taken into account, the efficiency may even be lower.
As far as I know, that’s generally the case: UV photocatalysis is usually used at low concentrations and with low air flow rates, or it’s just a formality meant to meet requirements superficially. If processing efficiency is to be ensured, it is necessary to increase the residence time; as a result, the equipment size must be enlarged, which means that the advantage of photo-oxidation equipment having a small footprint needs to be reconsidered.
Before, we used just one photocatalyst, but now we use two: lol
How are the effects of the two photocatalysts? The cost is not cheap either.
