Pengaruh Penambahan Konsentrasi (NH2)2CO Terhadap Karakteristik TiO2 dan Aktifitas Fotokatalitiknya Dalam Mendegradasi Methylene Blue

Abstract

Titanium dioxide (TiO₂) is a semiconductor material that is often applied as a photocatalyst. TiO₂ has a band gap of 3.20 eV which is less effective when used in visible light. Nitrogen dopants are dopants that have high effectiveness to improve the performance of TiO₂ in the visible light region. This study aims to determine the effect of adding nitrogen dopant concentration on the characteristics of TiO₂ and its photocatalytic activity in degrading methylene blue. The photocatalytic activity of TiO₂-N was tested with 10 ppm methylene blue under sunlight for 1 hour. The addition of dopants to the TiO₂ matrix has an effect on the band gap and photocatalytic activity of TiO₂
