DOI: 10.1016/j.catcom.2017.07.016
Abstract: Abstract TS-1 was post-modified by ammonium salts or tetrapropylammonium hydroxide (TPAOH). During the ammonium salts modification, the crystals were eroded and extra-framework titanium species were formed. After the combined-modification, hierarchical TS-1 with secondary pore volume… read more here.
