Pt-decorated mesoporous silica is directly prepared using a polymeric micelles assembly approach using an asymmetric triblock copolymer, poly(styrene-b-2-vinylpyridine-b-ethylene oxide) as the structure directing agent. Strongly immobilized, fully accessible, and uniformly dispersed Pt nanoparticles on mesoporous silica wall exhibit superior catalytic activity toward CO oxidation.

Ordered mesoporous, crystalline MgTa(2)O(6) thin films with a mesoscopic nanoarchitecture were synthesized by evaporation-induced self-assembly (EISA) in combination with a sol-gel procedure. Utilization of novel templates, namely the block copolymers KLE (poly(ethylene-co-butylene)-b-poly(ethylene oxide)) and PIB6000 (CH(3)C(CH(3))(2)(CH(2)C(CH(3))(2))(107)CH(2)C(CH(3))(2)C(6)H(4)O(CH(2)CH(2)O...

The oxygen reduction reaction (ORR)-one of the two half-reactions in fuel cells-is one of the bottlenecks that has prevented fuel cells from finding a wide range of applications today. This is because ORR is inherently a sluggish reaction; it is also because inexpensive and sustainable ORR electrocatalysts that are not only efficient but also are based on earth-abundant elements are hard to com...

Near-infrared (NIR) persistent phosphor ZnGa2O4:Cr3+ (ZGC) has unique deep-tissue rechargeable afterglow properties. However, the current synthesis leads to agglomerated products with irregular morphologies and wide size distributions. Herein, we report on in vivo rechargeable mesoporous SiO2/ZnGa2O4:Cr3+ (mZGC) afterglow NIR-emitting nanocomposites that are made by a simple, one-step mesoporou...

Cerium-rich metal oxide materials have recently emerged as promising candidates for the photocatalytic oxygen evolution reaction (OER). In this article, we report the synthesis of ordered mesoporous CuO/CeO₂ composite frameworks with different contents of copper(II) oxide and demonstrate their activity for photocatalytic O₂ production via UV-Vis light-driven oxidation of water. Mesoporous CuO/C...

A new electrochemical method to synthesize mesoporous nanowires of alloys has been developed. Electrochemical deposition in ionic liquid-in-water (IL/W) microemulsion has been successful to grow mesoporous CoPt nanowires in the interior of polycarbonate membranes. The viscosity of the medium was high, but it did not avoid the entrance of the microemulsion in the interior of the membrane's chann...

1. 1. Well-ordered Mesoporous Materials FSM-16 and M41S materials with regularly ordered mesopore arrangements and narrow pore-size distributions were fi rst described in the early 1990s1),2), and the mesostructures of silica and various metal oxides have since attracted much attention from chemists and materials scientists because of emerging applications in catalysis, adsorption, sensors, and...

We report the direct fabrication of mesoporous zeolite with a hollow spherical/ellipsoidal capsule structure by using conventional TPAOH and CTAB as soft micro- and mesopore generating templates; the mesoporous zeolite shows a high surface area of 717 m(2) g(-1) and small mesopore size of around 3 nm.

Hollow silica tubes with mesoporous wall structure were synthesized through the sol-gel reactions of tetraethoxysilane and n-octadecyltrimethoxysilane (TEOS/C18-TMS) on the surface of ammonium dl-tartrate crystals. Novel hollow carbon tubes with mesoporous walls and rectangular-shaped channels were fabricated using the silica tubes as templates.

We demonstrate here for the first time an original and facile approach to synthesizing a novel TiO(2) tube with a spiny mesoporous wall. The photocatalytic activity of the spiny mesoporous tube was greatly enhanced owing to the superior light reflecting ability of the tubular structure as well as the crosslinked spiny nanosheets.
