封面特征显示了M1相MoVTeNb混合氧化物的一维孔内丙烷向丙烯和丙烯醛的顺序转化。在他们的论文中，Y。Liu，中国粘蝇A. Twombly等人的研究表明，这些孔紧密地限制了直链烷烃和烯烃，并通过货车德瓦尔斯稳定化提高了C-H活化的速率，但在这些孔内可接近的桥连晶格O原子处形成C-O键的空间位阻减少了烯烃中C= C键附近的O插入。这种C-H活化增强和C-O形成减少一起提高了对脱氢和烯丙基氧化产物的选择性。更多信息可以在Y的论文全文中找到。Liu，中国粘蝇A.托姆布利等人
The Cover Feature shows sequential conversions of propane to propene and acrolein inside one-dimensional pores of M1 phase MoVTeNb mixed oxide. In their Full Paper, Y. Liu, A. Twombly et al. show that the pores tightly confine linear alkanes and alkenes and enhance rates of C− H activations via van der Waals stabilization, but steric hindrance to forming C− O bonds at the MOM bridging lattice O-atoms accessible within these pores diminishes O-insertion near C= C bonds in alkenes. This C− H activation enhancement and C− O formation diminution together improves selectivity to dehydrogenation and allylic oxidation products. More information can be found in the Full Paper by Y. Liu, A. Twombly et al.
