Abstract:
Good organic adsorption materials such as hydroxyapatite (HAp), has been
synthesized from bovine bones and used as supporting material for photocatalyst. In this
work, ZnO photocatalyst and Ag2O semiconducting material were chosen to improve
photocatalytic reaction. Pure HAp from bovine bones was prepared by calcination at high
temperature of 900 oC. Ag2O-ZnO/HAp photocatalyst were prepared by hydrothermal
method by using 3.0, 5.0, or 7.0wt% ZnO and fixed amount of Ag2O at 1.0wt%. The results
showed that HAp resembles white-yellow powder, porous and high roughness surface. X-ray
diffraction pattern showed 2θ positions at 31.8º, 32.2º and 32.9º, corresponding to primary
peaks of the HAp crystals. FT-IR spectra showed absorption peak at 3571 cm-1 represented
hydroxyl groups and absorption peaks at 1045, 961, and 563 cm-1 corresponding to phosphate
groups. The chemical analysis of HAp showed that the molar ratio of Ca:P was 1.56. The
catalytic activity testing for glycerol photo-reforming was performed in 5.0%vol glycerol
under N2 atmosphere with 50 mg of photocatalyst. The highest percentage of glycerol
conversion, 36%, was obtained by using Ag2O-ZnO/HAp photocatalyst containing 5.0wt%
ZnO and 1.0wt% Ag2O. The confirmation of hydrogen gas from glycerol photo-reforming
reaction was determined by using GC-TCD chromatography.
