Subject:
acetone; ambient temperature; benzene; butanol; catalytic activity; ethanol; ferric oxide; lithium batteries; methanol; nanoparticles; nanorods; pollutants; surfactants; titanium dioxide; toluene; volatile organic compounds; wastewater treatment; xylene
Abstract:
... In this paper, brookite-TiO₂/α-Fe₂O₃ heterostructured nanorods were synthesized by a facile two-step solution approach without using any templates or surfactants. α-Fe₂O₃ nanorods were first successfully obtained via a simple solution method at room temperature. The α-Fe₂O₃ nanorods were further employed as supports to construct nanoheterostructures for gas sensor application. The gas sensor based ...

Subject:
biobutanol; butanol; drying; nanoparticles; pervaporation; polymers
Abstract:
... Alcohol-permselective membranes may play an increasingly important role in bioalcohol production. Developments for this membrane mostly involve hybrid membranes. Obtaining high compatibility and nanodispersion of inorganic nanoparticles in the polymer matrix is the key to fabricating hybrid membranes with high pervaporation performance. In this study, a homogeneous, nanodisperse ZIF-8/PDMS membran ...

Subject:
autoclaves; butanol; chemistry; ferric oxide; iron; nanocomposites; nanoparticles; nanorods; temperature; urea; zinc oxide; zinc sulfate
Abstract:
... This paper reports a newly developed solvothermal strategy for the synthesis of ZnO-decorated α-Fe₂O₃ nanorods based on the reaction of α-Fe₂O₃ nanorods with zinc sulfate and urea in autoclaves at 180 °C. The resulting nanocomposites consist of porous α-Fe₂O₃ nanorods with diameters of 100–200 nm and a surface decorated with small ZnO nanoparticles (10–20 nm). The ZnO NPs are found to grow epitaxi ...

Abstract:
... Hierarchical porous materials especially the silica-based ones are undergoing rapid development due to potential applications in the fields of catalysis, adsorption, separation, and biomedical processes. Although various synthesis methods involving emulsions, colloids, and surfactants have been reported, synthesis of hierarchical porous silicas (HPS) with complex mesophase transformations by using ...

Abstract:
... The synthesis, characterization, and experimental validation of hierarchically structured, millimeter-sized SiO₂ spheres with high CO₂ uptake capacities have been systematically explored. The solvents employed during synthesis (aniline, benzyl alcohol and butanol) of the silica structures from alkoxisilanes strongly influence the physicochemical properties by controlling hydrolysis and condensatio ...

Abstract:
... The epichlorohydrin-N,N-dimethyl-1,3-diaminopropane copolymer (PCA) has been introduced for the first time as a meso-template to successfully synthesize a hierarchical ZSM-5 zeolite (PCA-ZSM-5) with mesopores of 7–50 nm in diameter by using small-sized nanoblocks. However, when its structural analogue epichlorohydrin–dimethylamine polyamine (PCS) is used, the obtained ZSM-5 zeolite (PCS-ZSM-5) has ...
