| 摘 要： | 采用ＦＴ－ＩＲ、ＴＰＳＲ－ＭＳ技术对ＺｎＯ上ＣＯ２／Ｈ２、甲醇、甲酸的表面吸附、反应物种进行了研究。研究发现，ＺｎＯ对ＣＯ２／Ｈ２合成甲醇反应具有活性，且反应的中间物种为双齿碳酸盐、甲酸盐及甲氧基。另外，还对单组份ＺｎＯ的作用及其表面反应机理提出了推论。

| Abstract: | The surface adsorption and reactive species of CO2/H2,methanol and formic acid over ZnO have been studied by FT-IR and TPSR-MS techniques.It has been found that ZnO is active for synthesis of CO2/H2 to methanol and the reactive intermediate spedes are bidentate carbonate,formate and methoxy.In the paper,the function of monocomponent ZnO and its surface reactive mechanism have been deduced. |
