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 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...

متن کاملGreen chemistry.
Gilbert's chemistry sets, those that many of today's practicing chemists received as children, proved to be the spark that ignited many a lifelong exploration of the wonders of chemistry. While DuPont was espousing its contributions to the world with its motto, "Better living through chemistry," children were using the popular Gilbert's chemistry sets to perform the simplest experiments and vie...
متن کاملGreen chemistry
Since their initial appearance in the scientific literature, the terms "green" and "sustainable" have been increasingly used and are nowadays ubiquitously present in the terminology of several research areas. The seminal origin of what is considered “green chemistry” today might be ascribed to the launch of the Responsible Care® initiative by the American Chemistry Council (ACC) [1] and to the ...
