Enhancing selectivity towards specific products remains a pivotal challenge in energy catalysis. Herein, we present strategy to refine via pathway optimization, exemplified by the rational design of catalysts for methanol steam reforming. Over traditional Pd/ZnO catalysts, direct decomposition key intermediates CH2O* into CO and H2 on PdZn alloys competes with oxidation CO2, leading inferior product distribution. To address this challenge, Cu is introduced modify catalytic dynamics, lowering dissociation barrier water provide more active hydroxyl groups CH2O*. Simultaneously, desorption PdCu elevated, thereby hindering decomposition. This dual functionality enhances both activity reforming reaction. By modulating activation patterns intermediate species, approach provides new insights catalyst improved reaction selectivity. Improving Here, authors introduce refining through

Abstract Ternary Cu/ZnO/Al 2 O 3 catalysts are one of the most important industrial and show excellent activity in methanol reforming reaction. However, it is challenging to elucidate metal support interactions, which critically influence catalyst structure performance, due their environmentally sensitive nature. This study examines interactions between Cu Al ZnO, after reductive treatments Cu/Al Cu/ZnO model with varying temperatures hydrogen concentration. A combination Brunner‐Emmet‐Teller (BET) measurements, X‐ray diffraction (XRD), N titration, diffuse reflectance infrared Fourier transformations spectroscopy (DRIFTS) high‐resolution transmission electron microscopy (HRTEM) provided comprehensive insights into structural evolution catalysts.
