Preparation of the Hierarchical Ti-Rich TS-1 via TritonX-100-Assisted Synthetic Strategy for the Direct Oxidation of Benzene
Abstract A new route to synthesis hierarchical Ti-rich TS-1 with uniform intracrystalline mesopores, uniform crystal size and the higher Ti content has been developed by using the environmental-friendly and cheap surfactant Triton X-100 as the assisted template agent and (NH 4 ) 2 CO 3 as crystallization-mediating agent. In this way, the surface area and pore volume of the resulting materials can be adjusted by the Triton X-100 content. The catalytic properties of the Nano-size hierarchical Ti-rich TS-1 were investigated by hydroxylation of benzene to phenol with H 2 O 2 as oxidizing agent and deionized water as solvent. Due to the combination of hierarchical pores and high titanium content, the hierarchical Ti-rich TS-1 shows improved catalytic activity in the oxidation of benzene. Graphical Abstract
