In this study, the magnetic Cu/CuFe2O4 nanocomposite was successfully prepared by a one-pot solvothermal method and evaluated for catalytic activity in 4-nitrophenol (4-NP) reduction reaction methylene blue (MB) degradation reaction. The structure, surface morphology, properties of catalyst were characterized using several physicochemical methods such as Powder X-ray diffraction (PXRD), Fourier...
A new method, named "re-growth etching", which introduces a unique etchant "Au(I)", has been developed to fabricate large-sized porous gold nanostructures. The size of nanostructures and the number of pores can be regulated by the molar ratio of Ag and Au in the precursor. We have evaluated their performance by a model reaction of the reduction of 4-nitrophenol. The catalytic property of porous...
Inorganic polyphosphates, linear polymers of orthophosphate, occur naturally throughout biology and have many industrial applications. Their biodegradable nature makes them attractive for a multitude of uses, and it would be important to understand how polyphosphates are turned over enzymatically. Studies of inorganic polyphosphatases are, however, hampered by the lack of high-throughput method...
A pH-mediated enhancement of the graphene carbocatalyst activity for the reduction of 4-nitrophenol.
Using alkaline pH adjustment, the reaction between graphene oxide and L-ascorbic acid led to the formation of a carbocatalyst film with numerous graphene edges protruding out of basal planes, which had a markedly enhanced carbocatalytic activity for conversion of 4-nitrophenol to 4-aminophenol, as compared to that of the carbocatalyst counterpart without involving pH mediation.
