Abstract null null Two twin series of carbon replicas were synthesized by the acid-catalyzed precipitation polycondensation of various amounts of furfuryl alcohol in SBA-15 suspensions using water and toluene as reaction media. The textural and structural parameters, as well as the morphology of the polymer/silica carbonizates and corresponding replicas, were investigated comprehensively. It was found that the polarity of the reaction medium plays an essential role in the scenario of the deposit...

Abstract null null A sequence of phases between structural phases in ALPO4-5, commencing from the 4-coordinated aluminum atoms (tetrahedra) in the bare crystal, up to the formation of 6-coordinated (octahedra), and 5-coordinated (bipyramids) aluminum atoms upon the progressive increase of the sorbate water loading, was identified by means of density functional theory calculations, combined with Rietveld refinement of our measured XRD patterns, and produced a crystallographic information file (CI...

Abstract null null Mesoporous silica nanoparticles are promising candidates to deliver proteins, antibodies, and anticancer drugs and to be served as an adsorbent of various types of substrate. Herein, a theranostic approach, in the preparation of fluorescence-type mesoporous silica for pH-responsive delivery of anticancer drug, doxorubicin, is introduced. By this mean, three types of mesoporous silica were synthesized. The ordinary type of mesoporous silica nanoparticles containing propylamine ...

Abstract null null The capacitive performances of carbon materials greatly rely on the porous structure and conductive network. However, the compromise of carbon materials with suitable porosity and 3D conductive framework still exists difficulty. Herein, a hierarchical porous free-standing carbon nanofiber (CNF) membrane was obtained from electrospun cellulose acetate (CA) nanofiber membrane via one-step carbonization and activation process. The influence of carbonization temperature on microstr...

Abstract null null A series of low-sodium ultrastable Y zeolites (SiO2/Al2O3 ≈ 25) partially exchanged with different amounts of rare earth ions (RE2O3 = 0.55–3.32 wt%) was prepared and characterized by XRD, IR spectroscopy, elemental analysis, N2 adsorption, as well as 29Si and 27Al NMR. The effect of RE content on the number and relative strength of acid sites of REY zeolites was studied by IR spectroscopy of absorbed CO and pyridine. The increase in the RE content in the zeolites leads to a d...

Abstract null null Chicken eggshell, a by-product of food processing, has been considered as natural waste and causes a major waste disposal problem. Recently, eggshell wastes have attracted great attention because of their rich calcium sources, and they can turn trash into treasure by rational use. In this work, peanut shell-like calcium carbonate (CaCO3) materials were synthesized with chicken eggshell biowastes as starting materials via coprecipitation method. CaCO3 materials were characteriz...

Abstract null null Ordered mesoporous silicas are widely used in separation science and catalysis, however, their slow batch synthesis is a barrier to scale-up and new applications. SBA-15 is one of the most extensively studied and commercially available mesoporous silicas, whose textural properties can be readily tuned through judicious choice of synthesis conditions. Here we demonstrate the continuous flow synthesis of SBA-15 in high yield at 80 °C using a simple tube reactor without any mixin...

Abstract null null Microporous organic polyimides are well suited for carbon dioxide separation from gas mixtures based on their polar surface and their tendency towards ultramicroporosity. Nevertheless, their application potential is limited due to an inherent insolubility and infusibility, preventing an easy processing into functional objects like membranes. By establishing a three-step synthesis procedure for the literature known network NPI-I, here, a solution to this challenge is demonstrat...

Abstract null null Heavy metals are becoming a huge problem in the environment and lead is one of them. Lead is disposed into water systems from huge industries such as paint industry, mining, and electroplating. In this study, manganese oxide coated fly ash (MnO2-CFA) was synthesized and characterized. The BET surface area of CFA MnO2-CFA was 18.4196 m2/g, 3 times more than the raw CFA (5.9231 m2/g). Batch adsorption experiments indicated that the uptake of Pb2+ fitted well in a Elovich kinetic...

Abstract null null Herein, we successfully synthesized a 4-nitrobenzenesulfonyl (-O-SO2-Ph-NO2) functionalized Zr-UiO-66 MOF (1) material using 2-(((4-nitrophenyl)sulfonyl)oxy)terephthalic acid (H2BDC-O-SO2-Ph-NO2) linker and ZrCl4 metal salt under solvothermal reaction conditions. The MOF material displayed high thermal stability up to 370 °C under air atmosphere and considerable chemical stability in H2O, 1(M) HCl, acetic acid and aq. NaOH solution (pH 8 to 10). It also showed a large BET surf...
