SINTESIS LAPISAN TIPIS SENG OKSIDA DIDOPING PERAK (ZnO:Ag) DAN APLIKASINYA UNTUK PENDEGRADASI POLUTAN ORGANIK AIR
Abstract: Zinc Oxide (ZnO) is
a semiconductor material that is used for photo-catalyst to degrade organic
pollutants. The addition of doping silver (Ag) in ZnO can increase the
photo-catalytic activity in the degradation process. In this study, the
addition of doping Ag in ZnO thin film on a glass substrate deposition using
thermal spray coating method has influence on the micro-structure and
photo-degradation in presence of bacteria Escherichia coli (E. coli) as an
organic pollutants has been investigated. Micro-structure of ZnO : Ag layer were
characterized by Scanning Electron Microscopy (SEM) and photo-degradation
activities of bacteria were tested with Total Plate Counter (TPC). The results
show that doping Ag in ZnO give affect the topography of the surface that can
increase in amount of grains and grain size in order to increase the
photo-catalytic activity. It indicated by decrease in amount of E. coli
bacteria from the initial sample with percentage of degradation is 99,99951%
