“…5, an obvious peak for h-BN is detected around 1372.9 cm À1 , which belongs to the B-N tangential vibration mode (E 2g ) of h-BN, 55 showing the hexagonal phase structure. The E 2g peak of h-BN was still 56,57 respectively. In addition, the 249 cm À1 , 164 cm À1 and 107 cm À1 peaks were derived from the MoO 3 group of HPMo.…”

“…The traditional production route of benzaldehyde is the toluene chlorination and hydrolysis method. However, chlorine ion is inevitably left in the process, which is not easy to remove and produce a large amount of wastewater, resulting in environmental pollution and equipment corrosion [18][19][20]. What even worst is that benzaldehyde generated by this route cannot be used to synthesise certain high-quality compounds such as drugs or fragrances [21].…”

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 novel material of bismuth loaded on zirconia (Bi 2 O 3 /ZrO 2 ) is synthesized by simple wet-impregnation method and characterized by several techniques (P-XRD, TEM, SEM, BET, etc.). Bi 2 O 3 /ZrO 2 proved to be a good catalyst for the four-component, one-pot reaction to produce a new series of 2,4-dihydropyrano [2,3-c]pyrazole-3-carboxylate derivatives with excellent yields (91 to 98%) under mild conditions at RT with short reaction times (z20 min). The structures of the target molecules were confirmed by 1 H NMR, 13 C NMR, 15 N NMR, HRMS and FT-IR. The catalyst is easily separable and can be reused for six cycles without ostensible loss of activity. This method is inexpensive, atom-efficient and no chromatographic separations are needed. EtOH 15 98 a Reaction conditions: aromatic aldehydes (1 mmol), malononitrile (1 mmol), hydrazine hydrate (1 mmol), diethyl acetylenedicarboxylate (1 mmol) and solvent (5 mL) were stirred at room temperature. 16340 | RSC Adv., 2018, 8, 16336-16343 This journal is
