DOI: 10.1016/j.cej.2018.04.043
Abstract: Abstract The application of photocatalytic oxidation (PCO) in VOCs degradation is greatly hindered at high humidity levels. This is because VOCs compete with water molecules to adsorb on the generally hydrophilic photocatalyst surface, where photocatalytic… read more here.
