Abstract — Pho­to­cat­alyt­ic prod­ucts have been around for many years with use in numer­ous appli­ca­tions. Pho­to­cat­alyt­ic TiO2 is being used today in air purifi­ca­tion devices and as sur­face treat­ment and addi­tive in ceram­ics, cement, trans­porta­tion infra­struc­ture and glass. These prod­ucts are being uti­lized or eval­u­at­ed for their de-pol­lu­tion, self-clean­ing, anti-fun­gal, and envi­ron­men­tal improve­ment attrib­ut­es. Pho­to­cat­alyt­ic coat­ings are one of the tools we have which can be used to com­bat the air qual­i­ty issues. Many tri­als have been car­ried out using pho­to­cat­alyt­ic prod­ucts. For the first time, tri­als have shown, quan­ti­ta­tive­ly, the de-pol­lu­tion effect using chemil­lu­mi­nes­cence mon­i­tors over extend­ed peri­ods. This allows unam­bigu­ous sta­tis­ti­cal analy­sis which proves the tech­nol­o­gy is a cost effec­tive prac­ti­cal solu­tion to inner city pol­lu­tion prob­lems. In this pre­sen­ta­tion we eval­u­ate the effi­cien­cy of two types of pho­to­cat­alyt­ic prod­ucts with respect to the removal of haz­ardous NOx pol­lu­tion: pho­to­cat­alyt­ic paints and trans­par­ent clear coat­ings for con­crete sur­faces. The set­ting of impor­tant field test tri­als and the cor­re­spond­ing results are ana­lyzed and pre­sent­ed in details in this lec­ture.
