A nanocomposite (NC) of titanium (IV) oxide (TiO2) and molybdenum (VI) (MoO3) was synthesized using a hydrothermal route. Detailed analyses transmission electron microscopy, X-ray diffraction, fluorescence (XRF), Brunauer–Emmett–Teller (BET) isotherms, photoelectron spectroscopy, Raman, diffuse reflectance infrared Fourier transform spectroscopy were carried out confirmed the successful formati...

Deeper understanding of all aspect biomass thermochemical conversion is necessary as researchers pursue multiple avenues for energy and environmental sustainability. In this paper, the agglomerative accumulation soot observed, captured on inner surface exhaust pipe, during operation a top-lit updraft gasification system was evaluated to understand its nature qualities. The using Fourier Transfo...

Controlling the particle size as well porosity and shape of silica nanoparticles is always a big challenge while tuning their properties. Here, we designed cost-effective, novel, green synthetic method for preparation perforated hollow mesoporous (PHMS-1) using very minute amount cationic surfactant in o/w-type (castor oil water) emulsion at room temperature. The grafting Al(III) through post-s...

A synergetic effect of ultrasonic irradiation and yolk–shell nanocatalyst was examined for the synthesis spirooxindoles from isatin, malononitrile cyclohexanone. It found this contributory can be accelerated desired reaction toward obtaining highly pure products in excellent yields short times. The contains melamine anchored onto magnetic Fe3O4 nanoparticles were applied as active base catalyst...

The moisture sorption isotherms of Clinacanthus nutans (C. nutans) herbal leaves were established at three different temperatures 30°C, 40°C, and 50°C, water activity between 0.3–0.9 using a static gravimetric method. results showed that equilibrium content C. increased with increasing constant temperature for both desorption adsorption isotherms. In contrast, the decreased when all exhibited T...

Abstract. Thanks to their vast surface area, activated carbons are materials of great interest. They used as adsorbents for both liquid- and gaseous impurities. To improve properties, impregnation with different substances is conducted. In this paper, such an was done using copper(II), manganese(II), silver(I), zinc(II) salts. The aim compare the inner structure impregnated carbon a non-impregn...

The capture of CO2 from air via direct (DAC) is a promising way to reduce the carbon dioxide concentration in atmosphere. carbonation calcium-based adsorbents using ambient conditions particularly interesting for DAC due its high theoretical uptake capacity and low cost. In this paper, new preparation method synthetic calcium oxide-based pellets process was investigated. Their performance studi...

Abstract The theoretical and experimental Adsorption Isotherms (AI) are essential for the study of surface area porous structure in solid materials. Also, fractal dimension characterizes roughness a which means that smooth has two, whereas highly rugged approaches to three. So, although there several methods evaluate adsorption isotherms Fripiat proposal can be considered as generalization Brun...

Large amounts of oil-containing sludge (OS) are produced in the energy, industry and services sectors. It is mainly composed residual oil particulate matter, thus posing an environmental threat leading to resource depletion if it improperly handled. In this work, OS feedstock was thermally treated produce porously magnetic carbon composites (CC) using a pyrolysis-activation process. Using data ...
