This work investigated the possibility of incorporation of nickel into several mesostructured cellular foam (MCF) silica supports prepared at various aging times (1, 2, and 3 days) by using deposition-precipitation method followed by reducetion process and to look for the best support to obtain supported nickel catalyst with highest nickel loading and smallest size of nickel nanoparticles. The hydrothermal stability of mesostructured cellular silica foams (MCFs) was studied in detail for the first time, using a variety of techniques including transmission electron microscopy, nitrogen sorption, small-angle X-ray scattering, 29Si solid-state nuclear magnetic resonance, and Fourier transform infrared spectroscopy. 2020-01-01 · Due to its exceptional textural, morphological and mechanical properties, mesostructured cellular foam (MCF) silica is a suitable support material for enzyme immobilization. However, the simple and efficient protocol of enzyme immobilization using MCF is often overlooked.

Ordered Mesoporous and Microporous Materials with Heteroatoms. Herein, large pore mesostructured cellular silica foam coated magnetic oxide composites (MO@MCFs) with multilamellar vesicle shells (MO@MLVs) were obtained, which exhibited a large pore (>10 nm), strong magnetic response (38 emu g −1 ), excellent protein adsorption and slow drug-release capacity. You have access to this article. In this paper, a novel antibacterial hemostatic agent composed of mesostructured cellular silica foams (MCF) decorated with silver ions (MCF-Ag) was synthesized by hydrothermal method. Hemorrhage wound infected with Escherichia coli was applied to evaluate its antibacterial and hemostatic performance both in vitro and in vivo. Mesostructured cellular foam (MCF) silica is a very interesting new mesoporous silica material.

Triblock co-polymer PEO 20 PPO Mesostructured cellular foam silica support Au–Pt alloy nanoparticles were prepared by a facile one-pot method. • The formation of Au–Pt alloy nanoparticles results in particle size variation and lattice distortions. • Electron polarization leads to the increase of transferable d-orbital electrons on Au and Pt atoms. • Mesostructured cellular foam (MCF) silica spheres with different textual parameters were synthesized using a triblock copolymer as a template. The effects of acid concentration and aging time on the window size and morphology were discussed.
