Three ZnO catalysts were prepared by heat treatment of IRMOF-1 directly in air at different temperatures and their crystal structure, morphology, pore structure and surface alkalinity of the samplescharacterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Brunner?Emmet?Teller (BET) measurements and CO2 temperature programmed desorption (CO2-TPD). The results showed that ZnO was a typical mesoporous material with spherical structure, its BET surfcae area and pore size were 49.7m2/g ~ 62.2m2/g and 2.18nm~2.92nm, respectively. The catalytic activities of mesoporous ZnO microspheres investigated for the synthesis polycarbnate diol via diphenyl carbonate and neopentyl glycol (NPG). The results exhibited that the ZnO microsphere obtained at 500oC exhibited good catalytic activity in the transesterification of DPC and NPG. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书修改意见回复 -->
