Supported nano-silver composites, famous for large specific surface area, good dispersibility and high catalytic activity, have been widely used in chemistry and chemical engineering, biomedicine and new materials. In this paper, we report recent research progress on supported nano-silver
composites as reviewed from preparation techniques (chemical reduction, physical reduction and in-situ formation), types of supporters (organic and inorganic) and anti-microbial/catalytic activity. Firstly, the principles and merits/demerits of three preparation techniques for silver
nanoparticles are elaborated. Afterwards, preparation, structures and properties of supported nano-silver composites are summarized through different types of supporters, as well as their applications in catalytic reaction, pollutant control and antimicrobial. Furthermore, it has been demonstrated
that silver nanoparticles produced by in-situ formation are more stable and well-distributed, readily meeting the demands for practical applications. Finally, superior supporters for nano-silver composites should be of high specific surface area and good stability, non-expensive, environmentally
friendly and low-toxicity.
