In this work, a CuO–ZnO/SiO<small>₂</small> catalyst with highly dispersed CuO–ZnO interface active sites was synthesized, and the structure–activity relationship and deactivation mechanism were systematically investigated using a model reaction (the cyclodehydrogenation of 1-amino-2-propanol to 2,5-dimethylpyrazine) that simultaneously generates H<small>₂</small>O and H<small>₂</small>.

The results show that V<small>₂</small>CBi<small>₂</small> maintains excellent thermal stability under both room temperature (300 K) and high-temperature (500 K) conditions. In addition, V<small>₂</small>CBi<small>₂</small> itself exhibits excellent electrical conductivity, and its adsorption energies for Li/Na/K range from −1.55 to −2.05 eV, which is conducive to the formation of stable adsorption configurations. The diffusion barriers of Li/Na/K ions on V<small>₂</small>CBi<small>₂</small> range from 0.07 to 0.15 eV, and the extremely low diffusion barriers are conducive to improving battery rate performance.
