In this study, perovskite ZnTiO3 photocatalysts were fabricated by the sol–gel method. The photocatalytic capability was verified degradation of emerging contaminant, antibiotic amoxicillin (AMX). For preparation, parameters calcination temperature and additional amount polyvinylpyrrolidone (PVP) ammonia are discussed, including calcining (500, 600, 700, 800 °C), volume (750, 1500, 3000 ?L), we...
the control of the configuration of the nise nanostructural thin films with temperature
Abstract A series of α -MoO 3 -TiO 2 mixed oxides were prepared by calcining a mixture the heteropolyacid H PMo 12 O 40 and TiO at temperatures ranging from 350 °C to 600 °C. The thus characterized tested for oxidation cyclohexene oxidizing /CO . FTIR XRD characterizations showed that Keggin structure was preserved calcination below 400 Above 450 °C, Keggin’s collapses. analysis revealed as tem...
A novel ceramsite (MMSC) material was synthesised for phosphate removal from Municipal Solid Waste incineration bottom ash (MSWIBA) and Molybdenum tailings (MoT) as precursors with shell powders (SP) an additive. The optimal process conditions important parameters are the mass ratio of MSWIBA to MoT calcination temperature. effects addition SP on composite (MMS) resultant characterised in terms...
We report a facile strategy to synthesize silica nanoparticles-coated graphene oxide (GO-SiO2) nanohybrids in a water-alcohol mixture at room temperature. AFM observations revealed that silica nanoparticles with ca. 50 nm in size were densely and evenly covered on graphene oxide sheets. Due to the space layer of silica nanoparticles, micro-scale GO-SiO2 hybrid plates could be individually dispe...
Conductive ink using copper nanoparticles has attracted much attention in the printed electronics industry because of its low cost and high electrical conductivity. However, the problem of easy oxidation under heat and humidity conditions for copper material limits the wide applications. In this study, antioxidative copper inks were prepared by dispersing the nanoparticles in the solution, and ...
Propane conversion over alumina supported Pt and Rh (1 wt% metals loading) was examined under fuel rich conditions (C3H8:O2:He = 1:2.25:9) over the temperature range 450–650 C. Morphological characteristics of the catalyst materials were varied by calcining at selected temperatures between 500 and 1,200 C. X-ray diffraction and BET analysis showed the treatment generated catalyts metals with pa...
Abstract This paper creates hydraulic binders using waste and a low energy input. Cements are produced with bauxite refining residue (red mud-RM), blended limestone lime, fused at temperatures from 600 to 1200 °C. The Saudi RM investigated has significant Al Si but Ca. Therefore, lime (CaO) (CaCO 3 ) used, as source of calcium, harvest cementing hydrates.When calcining alone, reactive aluminium...
