Application of the environmental dimension of sustainable development in the urbanlandscape preservation (to reduce urban air pollution)

The general definition of sustainability in 1986, for thefirst time international Committee extensonenvironment sustainability as The confrontation theneeds of the present without compromising theresources of future generations to confortation presentday needs. Sustainability goals summarized in threefactors: Environmental, social, economic.Photocatalyst is called the group of catalysts that areactive when exposed to light and Speeds of chemicalreactions. In this paper, we study how to reduce airpollution by using a sequence of Photocatalyst in orderto improve the environmental sustainability of theapproach is discussed, the purpose of this paper is theuse of optical catalysts in the building industry that actively thwart environmental pollution and as a nicedecorative pattern is also used. Titanium Dioxide isphotocatalyst presented in this paper that activated inthe presence of ultraviolet light and reactiveneutralizing toxic substances within the building andconvert them into harmless substances، results show;this facade converts smoke particles into smallerparticles with less chemical hazards, carbon dioxideand water, other advantages of This facade is potentialrespondents self-cleaning, anti-fog clogging, long lifeand cost.
