| 摘 要： | 使用X光电子能谱(XPS)及高分辨电子能量损失谱(HREELS)研究了二氧化碳在铜表面的吸附及其光化学反应.通过实验条件控制将物理吸附及化学吸附的二氧化碳吸附物种分别分离在规整铜表面及无序铜表面上,并使用193 nm激光对其照射研究其相应的光化学反应.结果表明只有化学吸附的二氧化碳物种在光诱导下发生了解理反应,而物理吸附的二氧化碳未发生反应. |

| Abstract: | The adsorption and photochemistry of CO2 on ordered/disordered Cu surfaces were investigated using X-ray photoelectron and high resolution electron loss technique. Physisorbed CO2 and chemisorbed CO2δ- species were isolated on different faces. Studies on the photochemical behavior of physisorbed and chemisorbed species were conducted with 193 nm laser irradiation. No photoinduced reaction occurred with the physisorbed species. Photoinduced dissociation was seen with chemisorbed species. |
| Keywords: | Carbon dioxide Copper surface Chemical adsorption Photoinduced dissociation |
