Applications of carbon-TiO2 materials have attracted attention in nanotechnology due to their synergic effects. We report the immobilization of TiO2 on carbon prepared from residues of the plant Manihot, commercial TiO2 and glycerol. The objective was to obtain a moderate loading of the anatase phase by preserving the carbonaceous external surface and micropores of the composite. Two preparatio...

MIL-101(Cr), one of the most important prototypical MOFs, is well investigated and widely used in many scientific fields. With regard to MOF synthesis in general, the addition of a modifier is commonly used to improve the properties of the products. The effect of inorganic (mineral) and organic acid modifiers was thoroughly investigated in the synthesis of MIL-101(Cr) and HNO3 could increase th...

Biomedical waste is a collection of medical from diverse sources that pose major risk to human, plant, or animal life now in the future. It cannot be processed discarded off without proper processing. often burnt incineration plants, yielding Incinerated Waste Ash (IBMW) which disposed landfills, are not completely leak-proof. The impact IBMW ash as cement replacement on strength and permeabili...

Filter cake is one of the main waste products of zinc processing industries and it contains a high amount of toxic heavy metals. In this research in order to reduce heavy metals leachability in filter cake, Portland cement, natural pozzolan, diammonium phosphate (DAP), triple superphosphate (TSP), lime, zinc oxide and ground granulated blast furnace slag (GGBFS) have been used. This research’s ...

Three Moroccan clays, denoted A1, A3 and A5, were sampled from the Fez region with aim of potential use as aluminosilicate precursors for geopolymer synthesis. Each clay was subjected to calcination at 700 °C analyzed using DTA/TG, grain size distribution measurements, XRD, FTIR spectroscopy before after heat treatment. The results showed that three clays contain kaolinite in different proporti...

This study investigated the preparation of new adsorbent based PANI and Kieselguhr (KG). The produced materials were characterized by XRD, XPS, TEM, FTIR, TGA BET. Thereby, hybrid material PANI@KG highest SBET values (about 47.82 m2 g−1). adsorption capacity PANI, KG tested on BPA ions from aqueous solutions at ambient temperature pH 6.0, maximum was observed to be 63.68 mg g−1 which is obtaine...

Currently, energy and extraction activities generate large amounts of highly polluting waste, so there is a need for sustainable environmentally friendly technologies. The aim the study to treat mining tailings fly ash through process geopolymerization. samples studied were obtained from Toquepala mine, Tacna ENGIE-Moquegua hydroelectric plant (Peru). methodology was based on two stages, first ...

Biomass upgrading is a promising approach to face the current energy consumption and chemicals production. Lignocellulosic biomass residues have taken lead in this field. In study, hemp residue-based activated carbons (ACs) were prepared by H3PO4-assisted hydrothermal carbonization (HTC) using low concentration of H3PO4 (25 wt%). ACs with high porosity development obtained (SBET > 1200 m2 g?1),...

This work studied the effect of nitrogen functional group modification on activated carbon synthesized from vetiver root waste pores development. Synthesis was carried out by hydrothermal carbonization at a temperature 225 ⁰C for 18 hours followed chemical activation using K2FeO4as agent in furnace 800 2 with atmosphere flowed rate 100 mL/minute. Urea used as source. The variation urea concentr...
