A novel method of preparing thermally stable zirconia-based mesoporous materials was developed. The zirconia-based mesoporous materials of 2D-hexagonal structure were prepared using zirconium sulfate as the zirconium precursor and cetyltrimethylammonium (CTMA) as the pore-directing agent with the aid of salt in the synthesis solution to reduce the sulfate content in the final product and signif...

The aim of this article is to review current knowledge related to the synthesis and characterization of sol gel-derived SBA-16 mesoporous silicas, as well as a review of the state of the art in this issue, to take stock of knowledge about current and future applications. The ease of the method of preparation, the orderly structure, size and shape of their pores and control, all these achievable...

Mesoporous gold sponges were prepared using 4-dimethylaminopyridine (DMAP)-stabilized Au seeds. This is a general process, which involves a simple template-free method, room temperature reduction of HAuCl4·4H2O with hydroxylamine. The formation process of mesoporous gold sponges could be accounted for the electrostatic interaction (the small Au nanoparticles (~3 nm) and the positively charged D...

Porous silicon is an excellent material for biosensing because of its large surface area and ability to filter out large contaminant species. In order to characterize the sensitivity of porous silicon based biosensors for biomolecules of different sizes, a mesoporous silicon waveguide with average pore diameter of 20 nm is used to detect single strand DNA oligos with different numbers of base p...

Considerable efforts have been devoted recently to design and fabrication of high performance and low cost electrocatalysts for oxygen evolution reaction (OER). However, catalytic activity of current electrocatalysts is usually restricted by high onset potential and limited active sites. Herein, we fabricated three-dimensional (3D) highly ordered mesoporous Pd-Co3O4 composite materials as excel...

Mesoporous, micro/nanosized TiO2/C composites with uniformly dispersed TiO2 nanoparticles embedded in a carbon matrix have been rationally designed and synthesized. In brief, TiO2 precursor was infiltrated into the channels of surface-oxidized mesoporous carbon (CMK-3) by means of electrostatic interaction, followed by in situ hydrolysis and growth of TiO2 nanocrystallites, resulting in ultrafi...

Expansion of native corn starch produces a high surface area mesoporous material capable of acting as a novel stationary phase for separating various mixtures of compounds.

A new SnO2/mesoporous silica composite was synthesized by a facile method, tin vapor reduction method , in which mesoporous silica SBA-15 was treated with tin vapor at temperature above 700 C under inert atmosphere. This material displays enhanced room-temperature photoluminescence (RT-PL) at increased treatment temperature. It is proved that RT-PL properties of this composite are closely relat...

A new molecularly imprinted mesoporous material (MIM) containing specific pockets for the extraction of diethyl phthalate (DEP) as copper complex has been prepared for the first time. The mesoporous material was developed by utilizing copper-phthalate complex (Cu-DEP) as the template molecule, 3-aminopropyltriethoxysilane (APS) as a functional monomer and tetraethoxyorthosilicate (TEOS) as the ...

An aptamer-capped mesoporous material for the selective and sensitive detection of α-thrombin in human plasma and serum has been prepared and characterised.
