Improving catalytic activity and selectivity as well as reusability of catalysts is an unavoidable challenge because of stringent economical and ecological desire for sustainability on account of the principle of “green chemistry” and “green technology”. The development of nanosciences and nanotechnologies make it possible to fabricate complicated artificial nanoarchitectures viathe elf-assemble and reorganization of different anisotropic nanoscale building blocks (nanocrystals, nanosheets, nanowires, and polyhedrons of oxides, metal, sulfide, and nitrite).

Among different kinds of acid catalysts, solid acid catalysts are attracting more attention owing to their obviously environmental benign characteristics with respect to weak corrosiveness, safety, high efficiency, easiness of separation and recovery. Solid acid nanosheets are promising because of their exotic physicochemical properties and high specific surface areas and tunable acidity. They represent a diverse and largely untapped source of basic building blocks for rational creating complicated nanocatalysts with designable microstructures and programmed propertiesthe. In addition, many nanoparticles could be employ as basic building blocks with nanosheets to induce some synergistic effects that could improve catalytic performance. Our research study indicated that nanoengineered solid acid catalysts exhibited improved catalytic performance for Friedel-Crafts alkylation, acetalization and photocatalytic reduction reactions. Here we mainly present some progresses in retrosynthesizing complication layered nanohybrids by using solid acid nanosheets, and understanding the relationships between microstructures and improved catalytic performance.
