چکیده

Рассмотрены возможности использования наноструктур станната цинка в качестве чувствительных элементов газовых сенсоров с высоким быстродействием, которые представляют большой интерес для самых разных областях применения от обнаружения токсичных веществ до мониторинга качества воздуха или медицинской диагностики. Синтез проводили при гидротермальной обработке наностержней растворе калия и мочевины различных концентрациях прекурсоров. Химический состав поверхности образцов проанализирован методом рентгеновской фотоэлектронной спектроскопии. Показано, что результате обработки на оксида появляются ионы Sn. Исследование газочувствительных характеристик проведено воздействии паров изопропилового спирта температурах 156°С 310°С. максимальный отклик 310°С к 1000 млн составляет 8,24. При этом образцы обладают быстродействием 23 с. The possibilities of using zinc stannate nanostructures as sensitive elements fast response gas sensors are considered, which great interest for use in a variety applications from the detection toxic substances to air quality monitoring or medical diagnostics. synthesis was carried out by hydrothermal treatment nanorods solution potassium and urea at different concentrations precursors. chemical composition sample surface analyzed X-ray photoelectron spectroscopy. It is shown that result treatment, Sn+ ions appear on oxide nanorods. study gas-sensitive characteristics under influence isopropyl alcohol vapors temperatures 156°C 310°C. maximum 310°C ppm At same time, samples have s.
