Abstract

Mesoporous tin oxide (m-SnO₂) was synthesized employing three different synthetic approaches namely, hard template, soft template and template-free hydrothermal route. KIT-6 was employed as the hard template, CTAB as the soft template and urea-assisted hydrothermal synthesis was employed in template-free route to obtain m-SnO₂. X-ray diffraction validated that tetragonal rutile phase of m-SnO₂ was formed in all the routes. The molecular bond structures of m-SnO₂ were studied using FTIR. Nitrogen adsorption–desorption isotherms demonstrated high surface area of the formed m-SnO₂. FESEM analysis verified the porous morphology of the synthesized m-SnO₂ samples. TEM analysis revealed the shape and size of the synthesized m-SnO₂ samples. All the routes yielded spherical SnO₂ particles. Steps explaining the formation of m-SnO₂ by all the three strategies are discussed in detail. The study evaluates the impact of using hard template (KIT-6), soft template (CTAB) and urea-assisted template-free strategy on the structural parameters namely surface area, pore diameter, pore volume and the grain size of m-SnO₂ particles. Large surface area and presence of mesopores makes synthesized m-SnO₂ a good candidate for several industrial applications particularly for gas sensing, drug delivery and catalysis.

介孔氧化锡颗粒的简易合成：合成路线的影响

采用硬模板法、软模板法和无模板水热法合成了介孔氧化锡（m-SnO2）。以KIT-6为硬模板，CTAB为软模板，采用无模板方式，尿素辅助水热合成m-SnO2。x射线衍射证实，在所有路线中均形成了m-SnO2的四方金红石相。用FTIR研究了m-SnO2的分子键结构。氮气吸附-解吸等温线表明，生成的m-SnO2具有较高的比表面积。FESEM分析证实了合成的m-SnO2样品的多孔形貌。TEM分析显示了合成的m-SnO2样品的形状和尺寸。所有路径均产生球形SnO2颗粒。详细讨论了通过所有三种策略解释m-SnO2形成的步骤。本研究评估了硬模板（KIT-6）、软模板（CTAB）和尿素辅助无模板策略对m-SnO2颗粒的结构参数表面积、孔径、孔体积和晶粒尺寸的影响。大的表面积和介孔的存在使合成的m-SnO2成为许多工业应用的良好候选者，特别是在气体传感，药物输送和催化方面。图形抽象
