Fenton (H2O2/Fe2+) system is a simple and efficient advanced oxidation technology (AOT) for the treatment of organic micropollutants in water soil. However, it suffers from some drawbacks including high amount catalyst, acid pH requirement, sludge formation slow regeneration Fe2+ ions. If these are surmounted, can be best choice AOT removal persistent organics In this work, was attempted to rep...

Compressed natural gas (CNG) is most appropriate an alternative of conventional fuel for automobiles. However, emissions of carbon-monoxide and methane from such vehicles adversely affect human health and environment. Consequently, to abate emissions from CNG vehicles, development of highly efficient and inexpensive catalysts is necessary. Thus, the present work attempts to scan the effects of ...

preparation of 2-chlorobenzonitrile, and benzonitrile are reported here from the corresponding 2-chlorobenzaldehyde and benzaldehyde by the reaction of ammonium hydroxide/vpo titania, vpo bulk (ammonium metavanadate) cucr catalyst/air system in methanol. all these catalysts showed better conversions with reasonable selectivity to aromatic. the results prove that bet surface area results show vp...

in ziegler-natta olefin polymerization, the pore architecture of catalysts plays a crucial role in catalyticperformances and polymer properties. while the type of preparation routes (such as chemical reaction andsolution precipitation) greatly affects the catalyst pore architecture as a result of different solidification mechanisms,the modification of the pore architecture within a given route ...
