“…6 The selective functionalisation of aromatic hydrocarbons is an important task in the industry; however, the cracking and oxidation of C-H bonds require high temperature, high pressure and efficiency catalysts, which are still a significant challenge [14,15]. Toluene is an aromatic compound that can be oxidised to benzyl alcohol, benzaldehyde and benzyl benzoate [16]. Among them, benzaldehyde is the simplest and most important product; it is widely used in food, pharmaceutical, perfume and pesticide industries [17].…”

Molybdenum vanadate is a novel vanadate. It is a functional material with good magnetic, electrical and catalytic properties. However, it is rarely used in the selective catalytic oxidation field, while the transition metal molybdenum and vanadium are usually used as a catalytic oxidation catalyst, the complex oxide and salt are naturally concerned. The structure of high-quality single crystalline Molybdenum vanadate (V 3.6 Mo 2.4 O 16) nanorods was synthesised by sol-gel method and high-temperature solid-state reaction. The effects of vanadium and molybdenum molar ratio and calcination temperature on the preparation of V 3.6 Mo 2.4 O 16 were studied. The structure of the catalyst was characterised by X-ray diffraction, thermogravimetry, X-ray photoelectron spectroscopy, scanning electron microscope and transmission electron microscope. The experimental results show that the molar ratio of vanadium-molybdenum is 10:7 when the precursor calcination temperature is 540°C, the single crystalline V 3.6 Mo 2.4 O 16 nanorods with regular shape has been obtained, the diameter of about 200 nm and the length up to tens of micrometres and the surface is smooth. Catalytic oxidation of toluene to benzaldehyde is used as a probe reaction for nanoV 3.6 Mo 2.4 O 16. The catalytic activity of the catalyst is good, the conversion of toluene is 39.8% and the selectivity of benzaldehyde is 70.1%.

A new catalytic route was established for oxidation of alcohols, imines formation, and knoevenagel condensation. Magnesium hydroxide and cerium oxide composite was synthesized using co-precipitation method and was employed in various organic transformations like oxidation, imines formation and knoevenagel condensation. Magnesium hydroxide and cerium oxide composite was characterized by fourier-transform Infrared (FT-IR), X-ray diffraction (XRD), scanning electron microscope (SEM) techniques. The effect of temperature, amount of catalyst, different solvents, and time-course were performed to find out the optimization condition for these three organic transformations. Results and Discussion Characterization of catalystsNickel cerium hydroxide (NiCe-HD), cobalt cerium hydroxide (CoCe-HD), mixed magnesium hydroxide and ceria (MgCe-HDO) and zinc ferric hydroxide (ZnFe-HD) were prepared using the co-precipitation method and were characterized with IR, XRD [a] R.
