Boron-incorporated nanosized HB-SUZ-4 showcased a noteworthy 24% boost in dimethyl ether carbonylation, with an elevation in methyl acetate selectivity from 91.8% to 96.0%. The improved performance is attributed to shortened diffusion lengths along the 8-member ring channels, decreased Brønsted acidity in the 10-member ring channels, and Lewis acid sites stabilizing CO.

用于 DME 羰基化的掺硼纳米 SUZ-4 沸石

掺硼纳米级 HB-SUZ-4 的二甲醚羰基化作用显着提高了 24%，乙酸甲酯选择性从 91.8% 提高到 96.0%。性能的改善归因于沿 8 元环通道的扩散长度缩短、10 元环通道中的布朗斯台德酸度降低以及路易斯酸位点稳定 CO。
