Catalytic efficiency of copper oxide in degradation of phenol using sintered calcium phosphate (SCaP) as catalyst support

摘要

For the first time sintered calcium phosphate is explored as catalyst-support, analogous to silica, alumina etc. The present work involves preparation of catalysts by depositing copper oxide over the sintered calcium phosphate using three techniques, viz., impregnation of CuO, impregnation of copper (II) nitrate & calcination, reduction of Cu~(2+) ions on the support & calcination. The above samples were characterized using XRD, UV-DRS, SEM-EDAX, BET surface area and acidity. Oxidation of phenol was studied with the above catalysts and sintered calcium phosphate was found to be an efficient catalyst-support.
