This work presents a facile, low-cost, and scalable strategy for fabricating monodisperse mesoporous silica nanospheres with tuneable particle size and pore structure, which serves as an excellent carrier for advanced solid acid catalysts.
A KCC-1/Al–SO3H catalyst with Si/Al = 5 was prepared to directly catalyse the synthesis of ethyl levulinate from cellulose in an ethanol/toluene co-solvent system. A reaction yield of 28.8 mol% was achieved after 6 h at 200 °C.
Using the modified phenanthroline ligand, the multicolor mesoporous silica nanospheres linked with lanthanide complexes were synthesized and characterized, and the application for cell imaging has been studied.
