Abstract:
(EN) A stannum-doped photocatalysized formaldehyde sensing material and a preparation method thereof, and a formaldehyde sensor. The photocatalysized formaldehyde sensing material contains zinc oxide nanoparticles and a tin additive. The material is prepared by first dispersing pre-synthesized zinc oxide nanoparticles uniformly in a tin salt solution to obtain a solution A; then, stirring the solution A and evaporating the solvent to obtain a sediment B; and then calcining the sediment B at a high temperature to obtain a product C, i.e. a photocatalysized formaldehyde sensing material. By said method, a low-cost, high-sensitivity and high-selectivity photocatalysized formaldehyde sensing material is prepared, which can reduce the lower limit of detected formaldehyde to 0.1 ppm and improves the selectivity of the material to ethanol.
(FR) La présente invention concerne un matériau de détection de formaldéhyde photocatalysé dopé à l'étain et son procédé de préparation, et un capteur de formaldéhyde. Ledit matériau de détection de formaldéhyde photocatalysé contient des nanoparticules d'oxyde de zinc et un additif d'étain. Ledit matériau est préparé en dispersant d'abord des nanoparticules d'oxyde de zinc synthétisées au préalable de manière uniforme dans une solution de sel d'étain pour obtenir une solution A ; en mettant ensuite la solution A sous agitation et en évaporant le solvant pour obtenir un sédiment B ; et en calcinant ensuite le sédiment B à une température élevée pour obtenir un produit C, à savoir un matériau de détection formaldéhyde photocatalysé. Un matériau de détection de formaldéhyde photocatalysé est préparé à faibles coûts, à sensibilité élevée et à sélectivité élevée, par ledit procédé, qui peut réduire la limite inférieure de formaldéhyde détecté à 0,1 ppm et améliore la sélectivité du matériau à l'éthanol.
(ZH) 一种锡掺杂的光催化甲醛传感材料及其制备方法和甲醛传感器。该光催化甲醛传感材料包含氧化锌纳米颗粒及锡添加剂。制备该材料时,首先将预先合成的氧化锌纳米颗粒均匀分散在锡盐溶液中,得到溶液A;然后搅拌溶液A并蒸干溶剂,得到沉淀物B;然后对沉淀物B进行高温煅烧处理,得到产物C,即为光催化甲醛传感材料。通过该方法制备了一种低成本、高灵敏度、高选择性的光催化甲醛传感材料,能够将甲醛的检测下限降到0.1ppm,并且提高了材料对乙醇的选择性。
