[Produksi hidrogen dengan menggunakan metanol atau gliserol sebagai elektron donor pada fotokatalis TiO2, TiNT, Pt/TiO2 dan Pt/TiNT pada suhu reaksi dari 30 oC sampai dengan 70 oC telah diteliti. Metanol dan gliserol efektif sebagai elektron donor untuk produksi hidrogen secara fotokatalisis. Penggunaan metanol lebih unggul 10% dari gliserol pada semua katalis dalam total produksi hidrogen. Produksi hidrogen terbaik ditunjukkan oleh fotokatalis Pt(1%)/TiNT dengan metanol sebagai elektron donor, yaitu sebesar 2306 µmol/gcat, sementara total hidrogen dengan gliserol sebesar 2120 µmol/gcat. Penggunaan dopan Pt pada fotokatalis menghasilkan produksi hidrogen dua kali lebih besar dibandingkan dengan tanpa dopan.
Hidrogen production with methanol or glycerol as sacrificial agent using TiO2, TiO2 Nanotubes, Pt/TiO2 and Pt/TiO2 Nanotubes photocatalysts at reaction temperature 30 oC to 70 oC have been investigated. Methanol and glycerol were effective for hydrogen production and the best result was methanol with Pt(1%)/TiO2 that have 2306 µmol/gcat, meanwhile with glycerol only produce 2120 µmol/gcat. The other photocatalyst also have the same pattern, which metanol give 10% higher result on total hydrogen production. Catalyst with Pt give twice higher hydrogen production rather than with no Pt.;Hidrogen production with methanol or glycerol as sacrificial agent using TiO2, TiO2 Nanotubes, Pt/TiO2 and Pt/TiO2 Nanotubes photocatalysts at reaction temperature 30 oC to 70 oC have been investigated.
