The isomerization of estragole to trans-anethole is an important reaction and is industrially performed using an excess of NaOH or KOH in ethanol at high temperatures with very low selectivity. Simple Ru-based transition-metal complexes, under homogeneous, ionic liquid (IL)-supported (biphasic) and "solventless" conditions, can be used for this reaction. The selectivity of this reaction is more...
A series of ZnBr2 impregnated on rice husk ash silica catalysts were synthesised via the wet impregnation method for CO2 cycloaddition to styrene oxide reaction. The X-ray diffraction (XRD) analysis indicates that resulted in deterioration silica's pore channels. Catalyst with 0.5 w/w% Zn (0.5 wt %ZnBr2-SiO2) was highly active oxide. conversion (StO) 89.1 %, carbonate (SC) selectivity 92.1 % un...
The exploitation of visible-light active photocatalytic materials can potentially change the supply energy and deeply transform our world, giving access to a carbon neutral society. Currently, most photocatalysts are produced through low-ecofriendly, dispersive, fossil-based synthesis. Over last few years, research has focused on development innovative heterogeneous by design sustainable green ...
Here we have demonstrated a solventless plasma-based process that integrates low-cost, high throughput, high reproducibility and ecofriendly process for the functionalization of the next-generation point-of-care device platforms. Amine functionalities were deposited by plasma-enhanced chemical vapour deposition (PECVD) using a new precursor. The influence of the plasma RF power and the depositi...
