Hybridization produces the better: Colloidal hollow periodic mesoporous organosilica nanoparticles (HPMO NPs) with tunable compositions and highly hybridized nanostructures are successfully synthesized by a simple, easily scale-up but versatile silica-etching chemistry (alkaline or HF etching) for their applications in nano-fabrication and nano-medicine.

Employing conventional block copolymers as scaffold, a direct synthetic route of mesoporous zeolites has been developed with the assistance of post-steaming treatment. Such hierarchical micro/mesostructure demonstrated the greatly enhanced catalytic activity for probe reactions, such as cracking of triisopropylbenzene and esterification reactions involving bulky molecules, because of the increased external surface, and the diminished coke formation by the greatly shortened diffusion length in microporous networks.

Uniform CePO(4)@LaPO(4) and CePO(4):Tb(3+)@LaPO(4) one-dimensional single-crystalline nanocable heterostructures with highly enhanced photoluminescent emission have been synthesized via a mild and simple hydrothermal approach. The resulting one-dimensional single-crystalline nanocable heterostructures have smooth and uniform LaPO(4) sheaths, which is of great significance in effectively eliminating surface trap-states and suppressing the energy quenching in energy-transfer processes. The photoluminescence results for these one-dimensional nanocable heterostructures illustrate that the uniform LaPO(4) sheaths remarkably increase the luminescent efficiency.

The size distribution and dispersion of nanomaterials, in addition to their dimensions, are crucial for their performance. Ordered mesoporous materials (OMMs), due to their periodic and size-controllable pore channels (2-10 nm) and high surface areas, have been regarded as ''a natural micro-reactor'' to construct novel ordered and well dispersed nanocomposites with controlled size and size distribution. In this review, we overview the recent developments in nanomaterials preparation and properties from ordered mesoporous materials over the last five years, focusing on materials preparation methodology and special properties. Finally, the present and future research interests of nanocomposites from OMMs will also be discussed.

By kinetic control over the zeolite seed formation, we report the direct fabrication of hierarchical mesoporous zeolites using hexadecyl trimethyl ammonium bromide (CTAB) as the soft template in a conventional solution route. Nanometer-sized, subnanocrystal-type zeolite seeds with a high degree of polymerization are essential to prevent the formation of a separate amorphous mesoporous phase and the phase separation between the mesophase and zeolite crystals in the presence of CTAB and a certain amount of ethanol. The mechanisms for the formation of hierarchically porous zeolites in the solution process, including the effect of mother liquid aging, formation of subnanocrystal zeolite seeds and their self-assembly effect with CTAB, and the role of ethanol are proposed and discussed in detail. The prepared mesoporous ZSM-5 zeolite showed much higher catalytic activity than conventional counterparts for aldol condensations involving large molecules, especially in the synthesis of vesidryl.

We report the synthesis of a new hierarchical mesoporous TS-1 type zeolite by a simple steam-assisted crystallization method. This novel product exhibits high catalytic activity and a strongly prolonged lifetime in the selective oxidation of 2,3,6-trimethylphenol to trimethyl-p-benzoquinone.
