Abstract

Ag₂O/TiO₂ nanowires as catalyst for reduction reaction of 4-nitrophenol has been synthesized in this study with molten-salt route and followed by the impregnation method. Analysis by characterization results show that the addition of Ag₂O does not change TiO₂ crystal structure and morphology, and it was found that the impregnated Ag₂O has metal-support interactions with TiO₂ nanowires. Size distribution of TiO₂ nanowires structure along with the Ag₂O is known to be within the range of nanomaterial. TiO₂ nanowires has an average width of 339.706 nm, and the impregnated Ag₂O has an average diameter size of 19.873 nm respectively. The catalytic test performance shows that Ag₂O/TiO₂ nanowires has excellent result compared to the control sample morphology of Ag₂O/TiO₂ anatase. It is closely correlated with the electron transfer capability of TiO₂ nanowires structure and this shows that Ag₂O/TiO₂ nanowires is suitable for catalysis of 4-nitrophenol reduction reaction.
