The high band gap energy in the SnO2 semiconductor makes its photocatalytic activity not optimal. Band
gap energy is a combination of the valence band and conduction band in a semiconductor. Doping and
additives are added to SnO2 because they can reduce the band gap energy of SnO2 thereby increasing
its photocatalytic activity because it only requires low energy for excited electrons. The research aims to
see the effect of using vanadium doping and the additive Diethanolamine (DEA) on reducing the band gap
energy of SnO2. The synthesis method used in this research was the Sol-gel method. The SnO2 synthesis
results can be characterized using a Diffuse-Reflectance Spectrophotometer (UV-DRS). The results show
that pure SnO2 has a band gap energy of 3.48 eV, while SnO2 that has been doped and added with
additives has a band gap energy of 2.25 eV. Vanadium and DEA have been proven to be able to reduce
the band gap energy of SnO2 so that it can be used as a photocatalyst material
