“…Hydrogen, as a clean and high-energy fuel, has been regarded as a potential alternative energy source to replace traditional fossil fuels. − Numerous efforts have been devoted to the storage and transportation of hydrogen; − however, it is still far away from commercialization due to the high explosion risk and unbearable costs . In this case, methanol can be utilized as a hydrogen carrier to provide on-site hydrogen production for fuel cells via methanol steam reforming (MSR) reaction, − which is easily applied in existing transport networks of gasoline with a relatively lower explosion risk.…”

As a hydrogen carrier, methanol can be utilized to provide on-site hydrogen for fuel cells via a methanol steam reforming (MSR) reaction. The ternary Cu/ZnO/Al 2 O 3 catalyst presents outstanding catalytic activity and excellent CO 2 selectivity (>97%). The defects in the copper lattice (e.g., stacking fault or twinning), which are usually accompanied by microstrain, constitute the highly active sites in the Cu/ZnO/Al 2 O 3 catalyst. However, the strategies to rationally tune the lattice strain are still limited. Herein, we reported a facile approach to regulate the Cu lattice strain with various organic acids via the mechanochemical method. In the meanwhile, we developed a method to quantify the microstrain in the Cu lattice combining X-ray diffraction (XRD) and N 2 O titration techniques. The catalyst with abundant microstrain presents a superior turnover frequency value of 691 h −1 , and the correlation between turnover frequency and lattice strain proves the dominant role of defects of Cu particles in improving the catalytic performance. This insight into the lattice strain in Cu/ZnO/Al 2 O 3 offers an alternative approach to synthesize highly efficient catalysts with abundant defects in the Cu lattice.
