Ce-doped MnO mixed with polyvinylidene fluoride as an amplified ozone decomposition filter medium in humid conditions.

Ozone is a hazardous air pollutant with significant adverse effects on human health and the environment. With the growing industrial use of ozone, effective ozone removal systems have become essential, especially to protect workers' health. MnO-based catalysts offer substantial promise for ozone decomposition; however, a major challenge in their application is water molecule poisoning, particularly in high humidity conditions.

Kinetic and reaction mechanism of generated by-products in a photocatalytic oxidation reactor: Model development and validation.

Photocatalytic oxidation is a promising technology to control air pollution. However, the formation of hazardous by-products hinders the commercialization application of this technology. This paper reports the development of a novel by-products predictive model considering the mass transfer of the pollutant in the gas phase and kinetic reaction in the solid phase.

Hydrothermal/solvothermal synthesis and treatment of TiO for photocatalytic degradation of air pollutants: Preparation, characterization, properties, and performance.

Photocatalytic oxidation (PCO) is a well-known technology for air purification and has been extensively studied for removal of many air pollutants. Titanium dioxide (TiO) is the most investigated photocatalyst in the field of environmental remediation owed to its chemical stability, non-toxicity, and suitable positions of valence and conduction bands. Various preparation techniques including sol-gel, flame hydrolysis, water-in-oil microemulsion, chemical vapour deposition, solvothermal, and hydrothermal have been employed to obtain TiO materials.

Performance of ultraviolet photocatalytic oxidation for indoor air applications: systematic experimental evaluation.

Photocatalytic oxidation (PCO) is a promising technology that has potential to be applied in mechanically ventilated buildings to improve indoor air quality (IAQ). However, the major research studies were done in bench-top scale reactors under ideal reaction conditions. In addition, no study has been carried out on the investigation of the ozonation and photolysis effect using a pilot duct system.

Adsorption performance of titanium dioxide (TiO2) coated air filters for volatile organic compounds.

The photocatalytic oxidation (PCO) technology as an alternative method for air purification has been studied for decades and a variety of PCO models indicate that the adsorption of reactants on the catalyst surface is one of the major physical and chemical processes occurring at a heterogeneous photocatalytic reaction. However, limited study explored the adsorption effect of a photocatalyst. This study carried out a systematic evaluation of adsorption performance of titanium dioxide (TiO(2)) coated fiberglass fibers (FGFs), TiO(2) coated carbon cloth fibers (CCFs), and original CCFs air filters at various relative humidity conditions for nine volatile organic compounds.
