Structural water molecules adsorbed on Au nanoparticles in the form of {OH − ·H 2 O@Au NPs} were identified as catalytical-active sites 4-nitrophenol reduction, which is extremely sensitive to subtle changes surrounding microenvironment.
A functional Cu(I) boron imidazolate framework (BIF) with a ladder-chain structure can not only change to another single-chain structure by incorporating 4,4'-bipyridine, but can also act as a reducing agent to load trimetal Au-Ag-Pd nanoparticles directly; the BIF with loaded noble NPs showed an excellent reduction effect on 4-nitrophenol. Moreover, we obtained a porous borocarbonitride by the...
The electrochemical behavior of o-nitrophenol was studied in detail with a glassy carbon electrode (GCE). The dependence of peak potential on pH indicated that equivalent electrons and protons were involved in the process of o-nitrophenol reduction. The interaction of o-nitrophenol with calf thymus DNA was investigated by adding DNA to the o-nitrophenol solution and by immobilizing DNA on GCE, ...
In this study, various concentrations of caffeic acid (CA) were used to synthesize gold nanoparticles (CA-AuNPs) in order to evaluate their catalytic activity in the 4-nitrophenol reduction reaction. To facilitate catalytic activity, caffeic acid was removed by centrifugation after synthesizing CA-AuNPs. The catalytic activity of CA-AuNPs was compared with that of centrifuged CA-AuNPs (cf-CA-Au...
The design and synthesis of novel cyanopropyl polysilsesquioxane hollow spheres lead to production of a highly active and stable catalyst in the reduction of 4-nitrophenol catalyzed by Au nanoparticles.
