A variety of water-tolerant, separable nanostructured solid acid catalysts have been synthesized. Layered-and nanosheet-tantalum molybdates were found to function as solid acid catalysts even in the presence of water. In addition, mesoporous niobium-tungsten mixed oxides have been synthesized, which exhibited remarkable catalytic performance. Moreover, efficient hydrolysis of cellulose have been achieved by using sulfonic acid groups attached magnetic silica nanoparticles.

已经合成了多种耐水、可分离的纳米结构固体酸催化剂。研究发现，即使在有水存在的情况下，层状和纳米片状钼酸钽也能起到固体酸催化剂的作用。此外，还合成了介孔铌钨混合氧化物，表现出显着的催化性能。此外，通过使用附有磺酸基团的磁性二氧化硅纳米粒子，已经实现了纤维素的有效水解。
