Enhanced photocatalytic and anti bacterial p erforman ce of nanosized Ag/ ZnO

The photocatalytic degradation of organ ic pollutants in water, using semiconductors such asTiO۲ and ZnO, has attracted extensive attention during the last two decades [۱]. Previous studies have prov ed that such semiconductors can degrade org anic pollutants and bacteria under UV light irradiation [۲]. However, the fast recombination rate of photogen erated electr on/hole pair hinders the commercialization of this techn ique. This has led to great intere st in improv ing the photocatalytic and antibacterial performance of se miconducto rs by suitable modification. In this work, we developed a facile low-temperature route to d eposit metal silver on the surface of spherical-shaped ZnO to form Ag/ZnO nanostru ctures.
