tile wastes in the catalytic direction. To this end, we use them as cost-effective, available, and nontoxic support materials for the heterogenization of sulfuric acid, in order to prepare the novel nano-ceramic tile waste supported sulfonic acid catalyst (nano-ceramic tile waste-SO3H or n-CTW-SA). This solid acid catalyst was well characterized through FT-IR, XRD, FE-SEM, EDX, TEM, TGA, BET, BJH, pH
关于废物产品/材料,由于环境和经济原因,回收或再利用具有举足轻重的作用。结果,当今的基本任务可以是发明新的实用途径以重用甚至回收它们。在此框架下,到目前为止,尚未考虑对某些废物的回收,例如瓷砖废物。因此,我们有可能在催化方向上回收瓷砖废料。为此,我们将它们用作具有成本效益的,无毒且无毒的硫酸杂化支撑材料,以制备新型的纳米陶瓷砖废料负载的磺酸催化剂(纳米陶瓷砖废料SO 3H或n-CTW-SA)。通过FT-IR,XRD,FE-SEM,EDX,TEM,TGA,BET,BJH,pH分析和哈米特酸度功能对这种固体酸催化剂进行了很好的表征。所制备的纳米陶瓷瓦废料负载的磺酸催化剂被证明是多组分反应(MRC)中的一种活性多相催化剂,可快速高效地一锅合成2,4,5-三取代和1,2,4, 5-四取代的咪唑具有高产率和高选择性。与其他一些均相和非均相催化剂相比,纳米陶瓷砖废料负载的磺酸显示出更高的活性。而且,高
