ABSTRACT 

Transformation phase TiO2 Rutile was conducted to improve the photocatalytic activity. This study evaluated the transformation phase of TiO2 rutile using the solid-state reaction method and tested for glycerol conversion reaction. A semiconductor material can be applied for glycerol conversion. The solid-state reaction using a mixture of TiO2 Rutile and sodium titanate in mole ratio 1:4 was heated to 750 oC. XRD analysis evaluated the transformation phase of the solid-state reaction product, while band gap energy was calculated following UV-Vis diffuse reflectance data. The photoactivity of glycerol was exposed by UV-Light at various times (5, 10, 15 h) of the liquid product and was analyzed by gas chromatography. Solid state reaction transformed TiO2 rutile to polymorph structure (TiO2 rutile, TiO2 anatase, and sodium titanate Na4O12Ti5). The band gap energy of the product was 3.2 eV. The optimum photocatalytic activity was 62.7% in glycerol concentration 0.25 M for a 15 h time reaction.
