研究了二氧化碳加氢甲烷化二组分、三组分担载型金属催化剂表面漫反射紫外可见光谱（ＤＲＵＶＳ）。根据ＤＲＵＶＳ提供的信息，揭示了催化剂组分间相互作用结果对催化活性的影响；不同助剂量催化剂ＤＲＵＶＳ特征强度与催化活性间定量关系也得到合理确定。
The diffuse reflectance UV-Vis spectra (DRUVS) of two-component, three-component supported metal catalysts for carbon dioxide hydromethanation were investigated. According to the information provided by DRUVS, the effect of the interaction between the catalyst components on the catalytic activity was revealed. The quantitative relationship between the characteristic intensities and the catalytic activities of the DRUVS catalysts was also determined reasonably.
