Plasma treatments environmental aspect

It must be noted that most studies on metal-doped TiCh are oriented toward the photo-oxidation of environmental pollutants (e.g., 4-nitrophenol,299 4-chloro-phenol300) rather than toward the photoelectrolysis of water (but see Section 6.4 of this Chapter). Other aspects of metal doping include the effect of UV radiation of Ag-doped Ti02 specimens,301 302 plasma treatment,303 and thermal treatment.304 Metal doping by ion implantation of I1O2 has been discussed.91,305...
