Synthetic method of acetone-oriented multilayer CsxWO3/Ti3C2Tx composite material
The invention discloses a synthetic method of an acetone-oriented multi-layer CsxWO3/Ti3C2Tx composite material. The synthetic method comprises the following steps: preparing a precursor; the preparation method comprises the following steps: 1) weighing 1-3g of Ti3AlC2, weighing 20-30ml of HF solution, slowly adding Ti3AlC2 powder into the HF solution, mixing in a polytetrafluoroethylene beaker, and releasing a large amount of heat during mixing; 2) electromagnetically stirring to form a suspension, centrifuging, and washing with deionized water until the pH value of the solution is 6; (3) carrying out vacuum drying to obtain a black Ti < 3 > C < 2 > T < x > sample; 4) weighing 0.2-0.5 g of WCl6, dissolving the WCl6 in 50ml of absolute ethyl alcohol, violently stirring until the WCl6 is completely dissolved to obtain a faint yellow solution, adding 0.1-0.4 g of CsOH.H2O, uniformly mixing, and adding a certain amount of the Ti3C2Tx sample obtained in the step 3) and a certain amount of acetic acid to form a precursor solution; and (5) transferring the obtained precursor solution into a 100ml high-pressure reaction kettle, so as to obtain the CsxWO3/Ti3C2Tx composite material. The gas sensitive element prepared by the invention shows high response to acetone and relatively high detection limit.
本发明公开了一种面向丙酮的多层CsxWO3/Ti3C2Tx复合材料的合成方法，包括以下步骤；1)称取1～3g的Ti3AlC2，量取20～30ml HF溶液，将Ti3AlC2粉体缓慢加入HF溶液之中，在聚四氟乙烯烧杯之中混合，期间放出大量的热；2)电磁搅拌形成悬浮液，离心之后用去离子水洗涤至溶液pH＝6；3)使用真空干燥得到黑色Ti3C2Tx样品；4)称取0.2～0.5g WCl6溶解在50ml的无水乙醇中，剧烈搅拌至完全溶解，得到淡黄色溶液，再加入0.1～0.4g的CsOH·H2O，混合均匀后加入一定量步骤3)得到的Ti3C2Tx样品与一定量的乙酸，形成前驱液；5)将所得前驱液转移到100ml的高压反应釜中，即得到CsxWO3/Ti3C2Tx复合材料。本发明制备的气敏元件对丙酮表现出高响应，以及较高的检测限。
