In this study, the crystalline metal-organic framework (MOF) ZIF-67 was obtained using solvent-free ball milling method, which is a fast, simple, and economical green method without need to use solvents. Using impregnation platinum metal ions were loaded in MOF cavities. Various descriptive methods have been used explain prepared Pt@ZIF-67 compound, such as FTIR, BET, TEM, SEM, EDS, XRD, TGA, I...

Pseudomonas putida B2 is able to grow on o-nitrophenol (ONP) as the sole source of carbon and nitrogen. ONP was converted by a nitrophenol oxygenase to nitrite and catechol. Catechol was then attacked by a catechol 1,2-dioxygenase and further degraded through an ortho-cleavage pathway. ONP derivatives which were para-substituted with a methyl-, chloro-, carboxy-, formyl- or nitro-group failed t...

Composite nanostructure materials are widely used in catalysis. They exhibit several characteristics, such as the unique structural advantage and synergism among their components, which significantly enhances catalytic performance. In this work, CoPt nanoparticles reduced-graphene-oxide-based nanocomposite catalysts (rGO/CoPt, rGO/CoPt/Ag) were prepared by using a facile co-reduction strategy. ...
