| 摘 要： | 本文运用红外光谱研究了CO和H_2O在Ni基催化剂上的吸附和反应规律。证实了H_2O在催化剂上是解离吸附, 以OH的形式吸附在催化剂上, 在OH之间可能有氢键形成。CO有两种吸附态: 线式和桥式。预吸附H_2O使CO线式吸附态几乎消失, 桥式吸附峰红移了约30 cm~(-1)。在不同温度时, 对比了CO或表面碳与H_2O的反应, 发现表面碳更容易同水反应生成甲烷。

| Abstract: | The adsorption and reaction of CO and H_2O on Ni catalyst were studied using infrared spectroscopy. Some valuable results were obtained. 1. Adsorption of H_2O and CO Two types of adsorbed CO on Ni catalyst were identified by IR spectroscopy, the linear state (2060 cm~(-1)) and bridged state (1960 cm~(-1)). Above 200 ℃, disproportionation reaction of CO could occur, forming CO_2 and surface carbon. A wide absorption band at 3600—3100 cm~(-1) was observed when H_2O was adsorbed on the catalyst. The band belongs... |
