Abstract: In this communication we have demonstrated the synthesis of organosilica nanotubes with inner diameter of ∼6 nm and their carbonization to form carbon/silica composite nanotubes. Pd nanoparticles. encapsulated in the organosilica and carbon/silica nanotubes show different catalytic activities in the hydrogenation of cyclohexene.

Abstract: Smart yolk-shell nanoparticles (hollow nanoparticles with a movable core) with an acidic shell and a basic core were fabricated through an organosilane-assisted selective etching method and acted as efficient nanoreactors for catalyzing a deacetalization-Henry cascade reaction with high activity and high selectivity. This strategy is very promising for the design of multifunctional nanoreactors for cascade reactions.

Abstract: (R)-(+)-1,1'-Bi-2-naphthol ((R)-(+)-Binol)-functionalized (Binol=2,2'-dihydroxy-1,1'-binaphthyl) chiral mesoporous organosilica nanospheres with uniform particle size (100 to 300 nm) have been synthesized by co-condensation of tetraethoxysilane and (R)-2,2'-di(methoxymethyl)oxy-6,6'-di(1-propyl trimethoxysilyl)-1,1'-binaphthyl in a basic medium with cetyltrimethylammonium bromide as the template. Nanospheres with a radiative 2D hexagonal channel arrangement exhibit higher enantioselectivity and turnover frequency than those with a penetrating 2D hexagonal channel arrangement (94 versus 88 % and 43 versus 15 h(-1), respectively) in the asymmetric addition of diethylzinc to aldehydes. In addition, under similar conditions, the enantioselectivity of the nanospheres can be greatly improved as the structural order of the framework increases. These results clearly show that the structural order of nanospheres affects enantioselective reactions. The enantioselectivity of the nanospheres synthesized by the co-condensation method is higher than that of nanospheres prepared by a grafting method and even higher than that of their homogeneous counterpart. These results indicate that the bite angle of (R)-(+)-Binol bridging in a more rigid porous network is in a more favorable position for achieving higher enantioselectivity. The efficiency of a co-condensation method for the synthesis of high-performance heterogeneous asymmetric catalysts is also reported.

Abstract: Developing highly active and stable nonprecious metal catalysts for electrochemical reactions is desirable but remains a great challenge. Herein, we report a novel metal-ion adsorption-pyrolysis strategy for the controllable zeolitic imidazolate framework-8 derived synthesis of in idual high-quality N-doped carbon nanotubes embedded with well-dispersed nonprecious metal nanoparticles, which exhibit superior electrocatalytic activity and stability for electrochemical CO

Abstract: Secondary building blocks within the cavities of primary silica-architecture building blocks are successfully engineered. The immobilized surfactant directs the selective dissolution and reassembly of dissolved silicate species for the formation of secondary building blocks (hollow nanospheres/nanorods see figure). Supported TiO(2) on nanostructures with multilevel interiors is shown to exhibit significantly enhanced activity in photocatalytic H(2) production.

Abstract: 3-D flowerlike mesoporous architectures constructed by the ultrathin perpendicularly aligned mesoporous nanoflakes synthesized via a cooperative layered calcium silicate hydrates and liquid crystal dual-templating approach show an enhanced asymmetric catalytic activity owing to the facilitated diffusion from the reduced thickness of perpendicularly aligned mesoporous nanoflakes.
