Ru nanoparticles loaded on a Keggin-type polyoxometalate (Cs(3)PW(12)O(40)), which did not possess strong intrinsic acidity, efficiently catalysed the conversions of cellobiose and cellulose into sorbitol in water medium in H(2) at ≤433 K. The Brønsted acid sites generated in situ from H(2) have been demonstrated to play a key role in the formation of sorbitol.
负载于 Keggin 型多金属氧酸盐(Cs(3)PW(12)O(40))上的 Ru 纳米粒子在水中和 H2 中,于 ≤433 K 下,将纤维二糖和纤维素高效地转化为山梨醇,而该多金属氧酸盐本身并不具有强固有酸性。业已证实,由 H2 原位生成的 Brønsted 酸位在山梨醇的形成中发挥了关键作用。
