Indoor Air Photocatalytic Decontamination by UV–Vis Activated CuS/SnO2/WO3 Heterostructure

Design of a novel photocatalytic gypsum plaster : with the indoor air purification property

This article addresses the design of a new photocatalytically active gypsum plaster. A hemihydrate in beta type is used as binder to design this material and a carbon modified TiO2 that can be activated by visible light is used as photocatalyst. An own developed test setup to assess the indoor air purification capacity of the developed material is presented. The new product possesses the indoor...

Understanding Mechanism of Photocatalytic Microbial Decontamination of Environmental Wastewater

Several photocatalytic nanoparticles are synthesized and studied for potential application for the degradation of organic and biological wastes. Although these materials degrade organic compounds by advance oxidation process, the exact mechanisms of microbial decontamination remains partially known. Understanding the real mechanisms of these materials for microbial cell death and growth inhibit...

Photocatalytic Removal of Escherichia Coli by ZnO Activated by Ultraviolet-C Light from Aqueous Solution

Abstract: Background and objectives: There is a great interest in photocatalytic oxidation of contaminants, using ZnO, in recent years. The main objective of this research was to study photocatalytic disinfection of E. coli bacteria as water microbial pollution index, using nano particles of ZnO and a UV lamp in a batch reactor. Material and Methods: In this study, the contaminated water sample...

Indoor Air Quality

The issues of indoor air quality are complex and can be directly influenced by a number of system and building parameters. There are no universal solutions for every problem since there are numerous potential contaminant sources. They may originate from indoors and have a direct impact on indoor environmental quality, or they may originate from outdoors and be transferred by a mechanical or nat...
