A silver-loaded zinc oxide (Ag/ZnO) photocatalyst was fabricated by chemical deposition, followed by an annealing process using a 405-nm -light-driven ZnO fiber. Silver oxide (Ag2 O) was deposited on the ZnO fiber with the same method of chemical deposition using a silver-nitrate solution. Ag2 O was also decomposed to Ag by annealing at 600 °C in a N2 flow. The authors found that the Ag/ZnO photocatalyst had a fiber structure and that there was 405-nm -light activity. The Ag/ZnO photocatalyst containing 0.02 at. % Ag obtained via a 3.7× 10-3 mol/l AgN O3 solution had the highest photocatalytic activity of all the samples.
