AbstractHydrodebenzylation of hexabenzylhexaazaisowurtzitane (HBIW) is one key step for the synthesis of High Energy Density Compound CL-20 (hexanitrohexaazaisowurtzitane). Design of a "high atom economy" debenzylation catalyst to promote the industry production and massive use in the fields of aerospace and military has attracted great attentions. Herein, we designed a catalyst of stick-like mesoporous titania supported ultrafine Pd nanoparticles with low loading 2 wt.% using a hydrothermal and then deposition-precipitation method. The supports and catalysts were thoroughly characterized by N-2 physisorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), Raman, ultraviolet-visible absorption (UV-vis), in situ diffuse reflectance infrared Fourier transform (DRIFT), H-2 chemisorption to determine their physical and chemical properties. The results revealed that stick-like titania (ST) treated at low temperature showed rutile crystalline structure, large interplanar spacing (3.2394 angstrom) and surface area (53 m(2)/g), small average crystallite size (63 nm) with mesoporous. The Pd can deposit into the interstices and lattice of ST and displayed ultrafine and even sub-nanometer sizes (average value 1.2 nm), and high dispersion. The Pd/ST-2 exhibited particularly high activity for hydrodebenzylation of HBIW. The product TADBIW was obtained in a high turnover number (TON) 107, which is 2 (similar to) 5 times higher than those of conventional Pd/C catalysts. This work paves a promising way to develop highly efficient catalysts with low loading of Pd and high atomic utilization for cost-effective synthesis of CL-20.
