3. • Katalis yang digunakan : P25 TiO2 (80% anatase, 20% rutile)
• Metal doped : Au(III)
• Panjang gelombang : 520-570 nm
• Aplikasi : Photooksidasi 2-prropanol
• Dengan tahap deposisi-presipitasi :
4. •Alasan digunakannya metal doped :
TiO2 dapat digunakan sebagai material fotokatalis dengan sinar
pada gelombang UV, sedangkan dalam aplikasinya akan digunakan
dengan sinar matahari dimana hanya mengandung 4% sinar UV dan
sisanya merupakan sinar visible. Sehingga TiO2 harus didoping
dengan metal agar dapat menyerap/digunakan pada sinar visible.
7. One of the key points of the use of the Au/TiO2 is the possibility to introduce response in
the material upon irradiation with visible light by excitation on the surface plasmon band
of gold. However, even in those cases in which visible light photocatalytic activity has
been observed for Au/TiO2,no conclusive evidence of the direct excitation of gold has
been obtained.
This mechanism of action, consisting of the excitation of gold to promote charge
separation, can be firmly supported by determining the photoresponse spectrum and
showing its coincidence with the surface plasmon band.
