“…[8][9][10] Studies have shown that the single metal oxide MoO 3 can exhibit excellent catalytic activity in alcohol dehydrogenation reactions, but MoO 3 alone is prone to phase change and deactivation during the catalytic process. 11,12 When MoO 3 and other Mo based oxides co-exist, they can form a synergistic effect with the main crystalline phase, which can signicantly improve the selectivity of the catalyst and prolong the service life of the catalyst. However, it is still difficult for the catalytic performance of Mo-V-O composite metal oxides to meet the needs of industrialization.…”
