Abstract

Effect of allophane from Gamalama volcanic soil to the properties of BiOI-allophane had been studied in this work. Composite of BiOI-allophane from Gamalama volcanic soil has the potential to be applied as a photocatalyst or photofuel under visible light radiation. Increasing the amount of allophane increase the surface area of 30.122 to 63.240 m2 g-1. Eg value of the resulted composite vary from 1.6-2.4 eV due to the various allophane amount.
