AbstractThe present paper shows a comparative study on the synthesis of nanostructured tin oxide in the ionic liquid 1-ethyl-3-methylimidazolium trifluoromethylsulfonate ([EMIm]TfO) by sol–gel and sonochemical methods. The XRD results of the synthesized materials revealed the formation of single tetragonal phase of SnO2by sol–gel method whereas a mixture of tetragonal SnO and orthorhombic SnO2phases was obtained by the sonochemical method. The sonochemical approach led to the formation of finer nanoparticales with a higher specific surface area than that of the sol–gel synthesized oxide. The average sizes of tin oxide nanoparticles were found to be about 30 nm and 15 nm for the particles obtained by sol–gel and sonochemical methods, respectively. The surface area of SnO2nanopowder obtained by the sol–gel method (calcined at 500 °C) was estimated to be 11.6 m2g−1, and the mean pore diameter was found to be 6.33 nm. Whereas the mixed SnO/SnO2sample (calcined at 500 °C) obtained by the sonochemical method exhibited a higher surface area of 43.11 m2g−1and an average pore diameter of 1.90 nm. The band gap of the synthesized tin oxides was estimated from the UV-vis. results to be 4.01 and 4.25 eV for the sol–gel and sonochemically synthesized samples, respectively.

Zno Powder

Zinc oxide nanopowder was prepared by sol-gel method using oxalic acid and zinc acetate as starting material for the first time. And Rhodamine B as the target material to study the different levels of ionic liquids on the photocatalytic performance of nano-ZnO. ZnO powder was determined by SEM and XRD for introduction of ionic liquids derived from nano-ZnO surface morphology and crystal before and after. The results show that nano-ZnO catalyst surface pores increased and grain refinement by adding ionic liquid which is conducive to nano-ZnO on the photocatalytic degradation of Rhodamine B.
