二氧化碳直接加氢转化为甲醇，既为二氧化碳的固定提供了一种可行的方法，也为氢气的储存提供了一种有效策略。基于此，分别采用水热法和共沉淀法制备了系列ZnO/MO x （M=Zr，Ti）催化剂，并将其用于催化CO2加氢制甲醇反应。评价结果显示，采用共沉淀法制备的20%ZnO/ZrO2-C催化剂表现出最优的催化活性。在反应温度为350 ℃、压力为3.0 MPa、质量空速为24 000 mL/（g·h）的条件下，CO2转化率达到9.0%，甲醇选择性为58.3%，甲醇的时空收率高达0.321 g/（g·h）。通过X射线粉末衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、H2程序升温还原（H2-TPR）、N2吸附-脱附实验、X光电子能谱（XPS）和CO2程序升温脱附（CO2-TPD）等表征手段，发现20%ZnO/ZrO2-C催化剂以固溶体形式存在，具有均一的介孔结构、较大的比表面积、较低的还原温度和较高的CO2活化能力。研究进一步表明，ZnO-ZrO2界面的形成对甲醇的合成具有重要的促进作用。适量的ZnO能够优化ZnO-ZrO2界面的形成，从而显著提升催化性能。

Direct hydrogenation of CO2 to methanol provides a viable method for the fixation of CO2，and also offers a strategy for storing hydrogen.In this study，a series of ZnO/MO x （M=Zr，Ti） catalysts for CO2 hydrogenation to methanol were synthesized by hydrothermal and co⁃precipitation methods，respectively.The activity evaluation indicated that 20%ZnO/ZrO2-C catalyst prepared by co⁃precipitation method exhibited the most excellent activation with a CO2 conversion of 9.0%，a methanol selectivity of 58.3%，while the methanol space time yield up to 0.321 g/（g·h） under the condition of 350 ℃，3.0 MPa and 24 000 mL/（g·h）.A series of structural characterizations were conducted，including X-ray powder diffraction，scanning electron microscopy，transmission electron microscopy，H2 temperature⁃programmed reduction，N2 adsorption⁃desorption，X-ray photoelectron spectroscopy and CO2 temperature⁃programmed desorption.It was demonstrated that 20%ZnO/ZrO2-C existed in the form of a solid solution state，which possessed relatively more uniform mesoporous structure，larger specific surface area，lower reduction temperature and high CO2 activation capability.It indicated that the ZnO-ZrO2 interface could be beneficial for methanol synthesis.The appropriate amount of ZnO was conducive to generating more ZnO-ZrO2 interface，thereby enhancing catalytic performance.
