Research progress of perovskite materials in photocatalysis- and photovoltaics-related energy conversion and environmental treatment.
Meeting the growing global energy demand is one of the important challenges of the 21st century. Currently over 80% of the world's energy requirements are supplied by the combustion of fossil fuels, which promotes global warming and has deleterious effects on our environment. Moreover, fossil fuels are non-renewable energy and will eventually be exhausted due to the high consumption rate. A new...
متن کاملApplication of Semiconductor Photocatalysis for Effective Elimination of Organic Contaminants from Sewage
The ZnO/SiO2 semiconductor nanophotocatalysis was synthesized via sol-gel method. Also, theplatinum particles were loaded on the ZnO/SiO2 nanoparticles by photoreductive method. Thestructure of catalyst was confirmed by X-ray diffraction (XRD), scanning electron microscopy(SEM) andfourier transform infrared spectroscopy (FT-IR). The XRD patterns of ZnO particlesdisplayed the nanoparticles have ...

Heterogeneous Photocatalysis Applied to Concrete Pavement for Air Remediation
In the present work the degradation of nitrogen oxides (NOx) by concrete paving stones containing TiO2 to be applied in road construction is studied. A kinetic model is proposed to describe the photocatalytic reaction of nitric oxide (NO) in a standard flow laminar photoreactor irradiated with UV lamps. In addition the influence of several parameters that can affect the performance of these sto...
