doping Ni, N, fotokatalis, TiO2, metilen biruAbstract
Sintesis dan karakterisasi material fotokatalis Ni-N-TiO2 menggunakan metode sol gel telah dilakukan. Tujuan riset adalah untuk mempelajari pengaruh doping Ni dan N terhadap TiO2 dengan prekusor Ti-butoksida yang akan digunakan untuk degradasi metilen biru. Sintesis dilakukan dengan memvariasi suhu kalsinasi, persen mol Ni dan persen mol N. Variasi suhu kalsinasi dilakukan pada suhu 400˚C; 500°C dan 600°C, variasi persen mol Ni dan persen mol N adalah 2,5%; 5% dan 10%. Sampel hasil sintesis dikarakterisasi menggunakan XRD, DR-UV, FTIR, SEM-EDX dan dilakukan uji ativitas degradasi metilen biru menggunakan spektrofotometer UV-Vis. Hasil analisis dengan XRD menunjukkan fasa anatas pada suhu 450oC pada puncak-puncak 25,35˚; 38,62˚; 48,09˚; 55,12˚; 62,75˚ dengan ukuran partikel masing-masing 8,48 nm; 12,1 nm dan 14,18 nm. Hasil karakterisasi DR-UV menunjukkan bahwa peningkatan persen mol Ni menurunkan nilai band gap TiO2, sedangkan untuk doping N terjadi hal sebaliknya. Untuk doping ganda Ni dan N, peningkatan salah satu dopan meningkatkan nilai band gap TiO2. Hasil karakterisasi dengan FTIR menunjukkan serapan utama pada daerah 500-900 cm-1 yang merupakan vibrasi ulur Ti-O pada TiO2, 3448 cm-1 merupakan vibrasi ulur O-H milik ikatan Ti-OH, dan serapan pada daerah 1635 cm-1 merupakan vibrasi tekuk O-H milik H2O. Spektrum 407,63 dan 1473,62 merupakan spektrum dari Ti-N dan N-O. Uji aktivitas katalis Ni-N-TiO2 menunjukkan waktu optimum degradasi pada menit ke 60 dengan persentase degradasi 60,15%.
