DOI: 10.1039/c9nj05793e
Abstract: A series of hierarchically structured HPW/titania–silica catalysts with micro-meso-macroporous structures and high specific surface areas are prepared through a co-precipitation method, adopting a cationic surfactant, STAB, and monodisperse PS microspheres as double templates. The effects… read more here.
