One-step generation of highly selective hydrogenation catalysts involving sub-nanometric Cu2O supported on mesoporous alumina: strategies to control their size and dispersion

Generation of alumina-supported dual sized small CuO particles (<1 nm) and larger CuO islands (35 nm) in air-calcined binary CuO-Al2O3 mesoporous materials prepared through direct synthesis, precursors of highly selective hydrogenation catalysts.
