In this study, it was aimed to develop new catalysts increase the conversion of environmentally harmful carbon dioxide gas methane which is a valuable fuel. By using natural clay mineral sepiolite (SEP) as support material; 6-8% (weight-weight) Ni-containing were prepared by impregnation. Catalysts characterized XRD and FT-IR analysis. Reaction conditions catalytic hydrogenation for production ...

During toxic Microcystis aeruginosa blooms, large amounts of cells can enter sediment through natural settlement, and coagulation treatment used to control water blooms can enhance the accumulation of cells. However, the current understanding of the fates of these cells and associated microcystins (MCs), as well as the effect of coagulation treatment on these factors, is limited. The results of...

Clay mineral growth can directly affect the chemistry and permeability of many natural systems, including soils, marine sediments, Earth surface waters, geothermal powerplants carbon dioxide storage sites. Notably, sluggish precipitation clay minerals has been hypothesised to hinder weathering rates. To date, there are limited data on rate effect aqueous solution saturation states these In this...

The sepiolite/ZrO2 composites were prepared by sepiolite (Sep) modification with zirconium propoxide in toluene at room temperature for 24 h (Sep–ZrI) or 95 °C 4 (sample Sep–ZrII). efficiency of the obtained removal phosphate from aqueous solutions initial pH = and 8 was investigated. Characterization samples shows that synthesis a higher shorter time provides slightly content amorphous Zr phas...

In the present study, coupling electro-Fenton (EF) and adsorption processes for textile industry wastewater remediation was investigated, in both batch continuous flow modes. Sepiolite used as an adsorbent coupled EF/adsorption processes. Various parameters such reaction time, current intensity, Fe2+ concentration, sepiolite dose, rate were found to affect efficiency of comparison single EF pro...

The present work aims at investigating the thermal properties of a wide range of semicrystalline nanocomposites based on poly(amide)-6 (PA6), ethylene-vinyl acetate copolymer (EVA), poly(ε-caprolactone) (PCL) or polypropylene (iPP), in combination with various types of nanofillers (layered silicates, carbon nanotubes, sepiolite, or POSS). We report on the effect of nanofillers on the quasi-isot...
