Researching, synthesizing and evaluating catalytic ability of nano Au / biochar system
Abstract
Biochar and Au/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 Au nano dispersed in the medium capillary. TEM image for the size of Au nanoparticles were 3-4nm. Investigation of the catalytic ability of curcumin reduction showed the transformation of tetrahydrocurcumin.
