Mesoporous CuO/CeO2 bimetal oxides were synthesized by a one-pot method using a cationic surfactant CTAB as structure directing agent and Cu(NO3)23H2O, Ce(NO3)6H2O and NaOH as the inorganic precurso...
A simple amperometric detection (AD) method based on mesoporous platinum (Pt) electrodes has been developed for the determination of sugars (glucose, fructose, and sucrose) with high-performance anion...
This paper describes the preparation and characterization of an optical pH-sensing device using a H+-responsive fluoroionophore based on boron-dipyrromethene, immobilized to a mesoporous silica thin f...
Due to its good burning characteristics and high cetane number, dimethylether (DME) is considered as a highly attractive and clean alternative to diesel fuel. This ether can be produced by methanol de...
Mesoporous lanthanum phosphate was synthesized by supramolecular self-assembly of cetyltrimethylammonium bromide and lanthanum nitrate following digestion in phosphoric acid. TGA-DTA, XRD and SEM were...
Two different ordered TiO2 structures were prepared as sol-gel films coated on glass and as mesoporous structures in order to study the effect, in 2-D or in 3-D, of bulk size on photocatalytic activit...
Pd-Si-structured novel mesoporous nanocomposite catalytic materials, having quite high Pd/Si ratios, were synthesized by an acidic direct hydrothermal synthesis route. The nanocomposite catalytic mate...
研究了以正硅酸乙酯(TEOS)和甲基三乙氧基硅烷(MeSi(OEt)3)为混合硅源,十六烷基三甲基溴化铵(CTAB)为模板剂,采取旋涂技术,在硅晶片表面制备出二氧化硅透明薄膜,再经过正硅酸乙酯(TEOS)蒸汽孔壁强化后采用线性升温焙烧法脱除薄膜孔道内的模板剂,制备出具有超低介电性能的氧化硅薄膜。使用FTIR、XRD和SEM对样品进行了结构表征,并采用阻抗分析仪测量了薄膜的介电常数(k),纳米硬度计...
