Biochar, nano Pt, hydrogenolysis/hydrogenation, curcumin, tetrahydrocurcuminAbstract
Biochar and Pt/biochar were successfully synthesized. This catalysts were characterized by TPD-N2, EDX, SEM and TEM techniques. The results of adsorption-desorption nitrogen showed a decrease in average volume and capillary diameter, indicating the presence of Pt nano dispersed in the medium capillary. TEM image for the size of Pt nanoparticles were 3-4nm. Investigate catalytic potential for curcumin conversion in methanol and ethanol, after 6 hours with Pt/biochar, the corresponding efficiency were 57.87% and 40.61% respectively. The presence of a new peak at a wavelength range is likely to be of tetrahydrocurcumin.
