Catalysis for green chemistry *
The use of heterogenization as a method for achieving clean synthesis is discussed. The chemical modification of mesoporous solids can be used to make a range of catalysts, including solid acids and bases, and stable metal complexes for selective oxidations and other reactions. By avoiding an aqueous quench stage in the separation, the heterogenization of catalysts and reagents can lead to subs...
متن کاملGreen polymer chemistry: enzyme catalysis for polymer functionalization.
Enzyme catalyzed reactions are green alternative approaches to functionalize polymers compared to conventional methods. This technique is especially advantageous due to the high selectivity, high efficiency, milder reaction conditions, and recyclability of enzymes. Selected reactions can be conducted under solventless conditions without the application of metal catalysts. Hence this process is ...
متن کاملNanoreactors for green catalysis
Sustainable and environmentally benign production are key drivers for developments in the chemical industrial sector, as protecting our planet has become a significant element that should be considered for every industrial breakthrough or technological advancement. As a result, the concept of green chemistry has been recently defined to guide chemists towards minimizing any harmful outcome of c...
متن کاملSurface Chemistry and Catalysis
Nowadays, heterogeneous catalysis plays a prominent role. The majority of industrial chemical processes, involving the manufacturing of commodity chemicals, pharmaceuticals, clean fuels, etc., as well as pollution abatement technologies, have a common catalytic origin. As catalysis proceeds at the surface, it is of paramount importance to gain insight into the fundamental understanding of local...
متن کاملGreen chemistry approach for the synthesis of CuO nanostructure
Molecular sieves MCM-41 were synthesized from rice husk ash (RHA) as alternative sources of silica. The material was synthesized by a room temperature method from a gel with the molar composition SiO2: 1.6EA: 0.215HDTMABr: 325H2O with pH correction. The cetyltrimethylammonium bromide (CTMABr) was used as a structure template. Nanocomposite containing 5.0 and 10.0 wt.% of Cu was synthesized unde...
