| Abstract: | Hydrotalcite-like compounds containing carbonate ion as the interlayer anion wereprepared by coprecipitation under low supersaturation condition by mixing an aqueous solu-tion of metal nitrates with an aqueous solutions of NaOH and Na2CO3 at room temperature,maintaining pH =8~10 with vigorous stirring- Following the mixing, the resulting heavyslurry was aged at 353 K for 18 h with vigorous stirring, The precipitate was then filtered,washed several times with hot distilled water and dried in air at 353 K overnight. In thisway, CuM1 AlCO3-HTLcs and M1 AlCO3-HTLcs were synthesized and characterized bymeans of XRD and lR. The catalysis of the above mentioned HTLcs were investigated in thephenol hydroxylatlon with H2O2- The results indicated that all of the copper-containingHTLcs had a higher catalytic activity in the reaction. However, those catalysts that did notcontaln copper had no catalytlc actlvlty in this reaction- This means that copper was the ac-tive center in the phenol hydroxylation. Meanwhile, the mechanism was also proposed,which could be used to explain the main reason for higher activity for CuCuAlCO3-HTLcs inthe phenol hydroxylation and the effect of Mg2+, Zn2+, Co2+, Ni2+ on activlty of CuM1 Al-CO3-HTLcs. |
