CeO_2 nanoplates with a hexagonal structure and their catalytic applications in highly selective hydrogenation of substituted nitroaromaticsf

摘要

CeO_2 nanoplates with a new hexagonal crystal structure (a = 15.30 A and c = 6.24 A) and uniform shape were synthesized and used as supports, showing high chemoselectivity for the catalytic hydrogenation of substituted nitroaromatics without sacrificing conversion under mild conditions.
