The hydrothermal synthesis of ZnO–NiO–NiFe2O4 nano-composite is reported. The sample was utilized to characterize via XRD, FE-SEM, EDS, FT-IR, UV–Vis, and BET techniques. The sample consisted of three different phases as ZnO (hexagonal), NiO (cubic), and NiFe2O4 (cubic) with the average particle size as 34 nm and specific surface area, average pore diameter, and pore volume as 64.35 m2 g−1, 13.02 nm
据报道水热合成了ZnO–NiO–NiFe 2 O 4纳米复合材料。该样品用于通过XRD,FE-SEM,EDS,FT-IR,UV-Vis和BET技术进行表征。样品由三个不同的相组成,分别为ZnO(六方),NiO(立方)和NiFe 2 O 4(立方),平均粒径为34 nm,比表面积,平均孔径和孔体积为64.35 m 2 克-1,13.02纳米,0.201厘米3 克-1, 分别。研究了纳米复合材料在热和超声辐照条件下合成噻唑烷丁-4-酮衍生物的催化行为。我们的结果表明,ZnO–NiO–NiFe 2 O 4纳米复合材料的催化活性远高于ZnO,NiO和NiFe 2 O 4金属氧化物。所有产品均以高收率和较短的反应时间制备。另外,催化剂被回收至少五次。

three-component reactionbetween amine, carbonyl compound and thioglycolic acid is now considered as a major strategy for synthesis of 1,3-thiazolidin-4-ones, which consists of the following steps: (i) condensation of aldehyde and amine which results the formation of an imine; (ii) the reactionbetween thioglycolic acid and the imine which is followed by an intramolecular cyclization reaction, which leads
An eco-friendly procedure for synthesis of 2-(2-oxo-2H-chromen-4-yl)-3-arylthiazolidin-4-one derivatives by three-component reaction of 2-oxo-2H-chromene-4-carbaldehydes, aromatic amines and thioglycolic acid, with tetramethylbutane-1,4-diammonium acetate as a low-cost ionic liquid catalyst under reflux condition is described. The use of an ionic liquid as a catalyst has the advantages of high yields, short reaction time and environmentally friendly reaction media.[GRAPHICS]
