Abstract: Owing to its semiconductor properties, tin(IV) oxide is widely used in gas sensors, photo- and electrocatalysis, fuel cells, electrolyzers etc. In this work, macroporous SnO2 samples are synthesized by impregnating polystyrene (PS) microspheres with sols containing SnCl4 and alcohol (96% ethanol, isopropanol, or n-butanol). After impregnation, the composites undergo drying and annealing. After drying, the same samples are washed with water for more complete hydrolysis followed by annealing. The resulting SnO2 samples are studied by powder X-ray diffraction, X-ray photoelectron spectroscopy, X-ray fluorescence analysis, low-temperature N2 adsorption (77 K), mercury porosimetry, and scanning electron microscopy. The effect of washing with alcohol and water on the porous characteristics and electrical conductivity of the materials is studied.
