In this work, sol-gel and chemical etching methods are adopted to synthesize zinc hydroxystannate materials. Cubic tin dioxide and zinc stannate composite materials with a definite structure are successfully prepared at varied annealing temperatures and times by using the synthesized zinc hydroxystannate as a sacrificial template. After a gas sensing test, tin dioxide and zinc stannate composite samples etched at 650 °C and annealed for 4 h exhibit a strong response and outstanding selectivity to hydrogen peroxide. Furthermore, the samples prepared under such conditions demonstrate long-term stability, and also a specified level of tolerance after the humidity stability test. Moreover, because of the simple preparation method and rapid detection of hydrogen peroxide, it is worth noting that samples prepared following the etching process at the 650 °C annealing temperature for 4 h exhibit the significant benefits of tin dioxide and zinc stannate composites. In this modern era, this research emphasizes the sample's potential for the rapid identification and detection of hydrogen peroxide.
在本工作中，采用溶胶-凝胶法和化学蚀刻法合成羟基锡酸锌材料。以合成的羟基锡酸锌为牺牲模板，在不同的退火温度和时间下成功制备了具有确定结构的立方二氧化锡和锡酸锌复合材料。经过气敏测试，在650℃蚀刻并退火4 h的二氧化锡和锡酸锌复合样品对过氧化氢表现出强烈的响应和出色的选择性。此外，在此条件下制备的样品具有长期稳定性，并且在湿度稳定性测试后也具有一定程度的耐受性。此外，由于制备方法简单且能快速检测过氧化氢，值得注意的是，在650℃退火温度下蚀刻4 h后制备的样品展现出二氧化锡和锡酸锌复合材料的显著优势。在当今时代，本研究强调了该样品在快速识别和检测过氧化氢方面的潜力。
