Descrizione generale

Silica, mesostructured (MCM-41) is a part of low-density organized mesoporous silicate system which has a 2D hexagonal phase, prepared in the presence of quaternary ammonium halide surfactant. It has ordered and large pores with diameter in the range 1.5-10 nm and specific surface area of 1500 m2/g.

Applicazioni

MCM-41 may be used as a base material that can be assembled with platinum complexes to develop luminescent oxygen sensing materials. It may also be used as an adsorbent in CO2 capture application. Surface functionalized MCM-41 may be used as a catalyst in the synthesis of bisphenol A.

Mesoporous Silica and their Applications

Mesoporous Materials Synthesis

Mesoporous materials are formed by a self-assembly process from combined solutions of sol-gel precursors (e.g., metal alkoxides) and structure-directing amphiphiles, usually block-copolymers or surfactants.

Recent Developments in Silicon Anode Materials for High Performance Lithium-Ion Batteries

Recent demand for electric and hybrid vehicles, coupled with a reduction in prices, has caused lithium-ion batteries (LIBs) to become an increasingly popular form of rechargeable battery technology.

Strategy for Toxicity Screening of Nanomaterials

A key challenge for nanomaterial safety assessment is the ability to handle the large number of newly engineered nanomaterials (ENMs), including developing cost-effective methods that can be used for hazard screening.
