The high stability of C–O bonds in diaryl ethers limits the valorization of lignin. Herein, reductive hydrolysis of C–O bonds in diaryl ethers was achieved over Pd nanoparticle/polyoxometalate–ionic liquid composite supported on SiO₂ (Pd/H₂[POM-IL]@SiO₂) in water, selectively yielding ketones free from their alcohol counterparts in unprecedentedly high yields (>80%).

SiO ₂上的钯纳米颗粒/多金属氧酸盐-离子液体复合材料作为多功能催化剂，可有效地从二芳基醚生产酮

二芳基醚中C–O键的高稳定性限制了木质素的增值作用。在此，在水中负载于SiO ₂（Pd / H ₂ [POM-IL] @SiO ₂）上的Pd纳米颗粒/多金属氧酸盐-离子液体复合材料上，实现了二芳基醚中C–O键的还原性水解，有选择地产生了不含它们的酮酒精同行的空前高产（> 80％）。
