Would the addition of UV light increase the conversion efficiency of CO and H2O in a water-gas shift reaction at a lower temperature? CuO coupled with ZnO is a good photocatalyst.
Yes! UV light is quite strong source of photons for activating a photocatalyst. Also, another point of consideration is what is your source of UV light? A hand held UV light lamp will have low light intensity as compared with 300 W High pressure Xe lamp. So one has to consider these points but nevertheless, exposing UV will enhance catalytic activity.
Thank you for answering, sir. I don't have any idea on what wattage of UV lamp I will use for a water-gas shift reaction at 200 deg C. Can you recommend a specific wattage? Would a UV lamp withstand that temperature?
Yes by using special kind of robust UV light source which can withstand temperature up to 700 degree Celsius. Kindly go through this link which might be useful for your research

Good luck.
Is using an ordinary UV lamp in the market dangerous?
UV light is dangerous so wearing protective anti-UV goggles and lab coat is always recommended.
