A dielectric barrier discharge reactor with inner electrode modified with metal oxides of Ti, Mn and Co has been designed and tested for the oxidation of diluted volatile organic compounds (VOCs) of different nature like toluene, isopropanol and trichloroethylene. It has been observed that at a fixed concentration of VOC, total oxidation of isopropanol is achieved at lower specific input energy...

The sorption of VOCs by different building materials can significantly affect VOC concentrations in indoor environments. In this paper, a new model has been developed for simulating VOC sorption and desorption rates of homogeneous building materials with constant diffusion coefficients and material-air partition coefficients. The model analytically solves the VOC sorption rate at the material-a...

This study examines inter-brand, intra-brand and intra-model variations in volatile organic chemical (VOC) levels inside new cars. The effect of temperature on interior VOC levels was examined using model automobiles with and without the air-conditioning running. Potential sources of VOC were assessed by comparing VOC levels with two interior trims (leather and fabric) and by analyzing VOC emis...

In this study, we made the heterojunction solar cells on Si substrate by fabricating a nanocrystalline Si/SiO2 superlattice emitter structure. Amorphous silicon and silicon dioxide superlattice were prepared by rf Si sputtering and plasma oxidation, respectively. The deposited amorphous silicon was crystallized at high temperature. Microstructure studies by TEM show that amorphous silicon was c...

This paper deals with the effect of catalyst loading on activity and selectivity CuOx−MnOy catalysts alumina-silicate supports (fiber material-Al2O3(44)/SiO2(56)). A special focus lies oxidation CO, mixtures VOC from 1-butene, isobutane, n-butane, propane, ethene, ethane, as well CO in presence NO2. The are prepared through wet impregnation filter section an aqueous solution copper manganese ni...

This study presents a high-resolution dynamical analysis of Volatile Organic Compound (VOC) concentrations measured from March 11 to April 4 2019 at Réunion Island during the BIO-MAÏDO (Bio-physicochemistry tropical clouds Maïdo: processes and impacts on secondary organic aerosols formation) campaign. We detail chemical that govern atmospheric VOC two targeted sites western slope Island: Petite...

Hollow cathode plasma sputtering is an advantageous method of preparing catalysts in the form thin oxide films on supports. Such are particularly suitable for processes such as catalytic total oxidation volatile organic compounds (VOCs), representing economically feasible and environmentally friendly VOC abatement. Catalysts with Ni:Co molar ratios 1:4, 1:1, 4:1 were prepared stainless-steel me...
