Photocatalytic degradation of Prozac® mediated by TiO nanoparticles obtained via three synthesis methods: sonochemical, microwave hydrothermal, and polymeric precursor.

Three different synthesis methods were applied to obtain TiO nanoparticles: microwave-assisted hydrothermal (TiO-MW), sonochemical (TiO-US), and polymeric precursor (TiO-PP). The nanoparticles thus obtained presented 93% (TiO-MW) and 92% (TiO-US) anatase phase, and TiO-PP 93% rutile phase. The TiO-US sample performed best during the Prozac® photodegradation assays because of its lipophilic surface, attributable to the C-H groups therein.

NiMo-NiCu Inexpensive Composite with High Activity for Hydrogen Evolution Reaction.

In this work, the effect of copper addition on NiMo coating is evaluated in regard to the hydrogen evolution reaction (HER). NiMo and NiMo-NiCu composites are prepared by a simple coelectrodeposition process. The effect of Cu on deposit characters were tested by varying it in the range of 0.
