The CuO-CeO₂ catalyst with high Cu content and dispersion was prepared by pyrolysis of the self-assembled HKUST-1-CeO₂ composite, where HKUST-1 represented a typical metal organic framework Cu₃(btc)₂ (btc = benzene-1,3,5-tricarboxylate). The catalyst magnified remarkable performance under a gas hourly space velocity (GHSV) of 31,440 cm³ g⁻¹ h⁻¹, attaining H₂ production rate of 3648 ml kg_cat⁻¹ s⁻¹ with CO selectivity of 0.5% under 543 K. Characterization results demonstrated that high dispersion of active metal can facilitate oxygen species spillover, accounting for the remarkable catalytic behavior. In situ infrared Fourier transform spectroscopy (in situ DRIFT) disclosed the possible reaction pathway for methanol steam reforming (MSR) reaction.

通过自组装的HKUST-1-CeO ₂复合材料的热解制备了具有高Cu含量和分散性的CuO-CeO ₂催化剂，其中HKUST-1代表典型的金属有机骨架Cu ₃（btc）₂（btc =苯- 1,3,5-三羧酸盐）。在31,440 cm ³  g ^-1  h ^-1的气体时空速（GHSV）下，该催化剂具有显着的性能提升，H ₂生成速率达到3648 ml kg kg _cat ^-1  s ^-1在543 K下，CO的选择性为0.5％。表征结果表明，活性金属的高度分散可促进氧的外溢，这是其显着的催化行为。原位红外傅里叶变换光谱（原位DRIFT）公开了甲醇蒸汽重整（MSR）反应的可能反应途径。
