  Fabrication of hollow silica–zirconia composite spheres and their activity for hydrolytic dehydrogenation of ammonia borane

  摘要：

  In this paper, we report fabrication of hollow silica-zirconia composite spheres by polystyrene (PS) template method and control of wall thickness of the hollow spheres in nanoscale. Both the hollow spheres before and after calcination were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), elemental analysis, and powder X-ray diffraction analysis (XRD). Morphology of the hollow spheres does not significantly change after calcination from the results of SEM and TEM images, while the amount of residual PS templates drastically decreases via the calcination procedure from the results of FTIR and elemental analysis. The sample after calcination mainly includes amorphous silica from the results of XRD, indicating that the hollow silica-zirconia composite spheres consist of amorphous phases and/or fine particles. Wall thicknesses of the samples after calcination are controlled by adjusting the amount of PS template suspension, and hollow silica-zirconia composite spheres with the wall thicknesses of 17.5, 15.0, 10.0, and 2.0 nm are obtained using the PS template suspension of 25.0, 33.5, 100.0, and 400.0 g, respectively. The activities of the hollow spheres for hydrolytic dehydrogenation of ammonia borane (NH3BH3) were compared. The evolutions of 2.0, 3.1, 5.0, and 8.0 mL hydrogen from aqueous NH3BH3 solution were finished in about 4, 5, 3, and 7 min in the presence of the hollow spheres with wall thicknesses of 17.5, 15.0, 10.0, and 2.0 nm, respectively. The molar ratios of the hydrolytically generated hydrogen to the initial NH3BH3 in the presence of the hollow spheres with wall thicknesses of 17.5, 15.0, 10.0, and 2.0 nm are 0.5, 0.8, 1.4, and 2.0, respectively. The results indicate that the activity of hollow silica-zirconia composite spheres for hydrolytic dehydrogenation of NH3BH3 improves with decrease of wall thickness of the hollow spheres. From the results of BET adsorption measurements, specific surface area of the hollow spheres increases with decrease of wall thickness of the hollow spheres. The results of activity, specific surface area, and XRD profiles suggest that the primary particles form layer-like structure in the wall of hollow silica-zirconia composite spheres and the number of the layers depends on the wall thickness.

  Earth‐abundant first‐row transition‐metal nanoclusters (NCs) have been extensively investigated as catalysts. However, their catalytic activity is relatively low compared with noble metal NCs. Enhanced catalytic activity of cobalt NCs can be achieved by encapsulating Co NCs in soluble porous coordination cages (PCCs). Two cages, PCC‐2a and 2b, possess almost identical cavity in shape and size, while

  富含地球的第一行过渡金属纳米团簇（NCs）已作为催化剂进行了广泛研究。但是，与贵金属NCs相比，它们的催化活性相对较低。可以通过将Co NCs封装在可溶性多孔配位笼（PCC）中来提高钴NCs的催化活性。两个笼子PCC-2a和2b在形状和大小上具有几乎相同的空腔，而PCC-2a的净电荷是PCC-2b的五倍。钴2+阳离子在PCC-2a中积累，并就地还原为超小型Co NCs，而对于PCC-2b，仅形成大体积的Co颗粒。结果，在所有第一行过渡金属NC中，Co NCs @ PCC-2a在硼烷铵的水解中实现了最高的催化活性。根据这些结果，可以预见，将电荷限制在带电的多孔配位笼中可能是合成具有超常性能的超小型NC的一条新途径。
