Fe and Ni doped mesoporous Co3O4 (mCo3O4) catalysts were prepared and investigated for electrochemical oxygen evolution. The incorporation of Fe into mCo3O4 (Fe-mCo3O4) results in unusual synergistic effects via destruction of the bulk mesoporous structure and formation of slit-like pores. The Fe-mCo3O4 composite displayed a significantly enhanced catalytic activity for oxygen evolution.

3D mesoporous graphene (mesoG) was synthesized from [Ni2(EDTA)] (EDTA = ethylenediaminetetraacetate). The material is comprised of interconnected 4 nm-sized hollow carbon shells composed of 3-4 layers of graphene and exhibits high bifunctional electrocatalytic activity as well as high durability for use in oxygen evolution and reduction reactions.

The present research reports the synthesis of poly-N-isopropylacrylamide / mesoporous carbon composites, prepared by radical polymerization of N-isopropylacrylamide inside mesoporous carbon pores functionalized with carboxylic groups. The deposition of poly-N-isopropylacrylamide on mesoporous carbon was confirmed by FT-IR spectroscopy, TEM, N2-sorption measurements. The mesoporous carbon materi...

ordered mesoporous carbon cmk-3 (omc) have been synthesized using mesoporous sba-15 silica as template and modified with cobalt carbonate. morphologies and surface texturing of materials werecharacterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and n2 adsorption-desorptionisotherms. the cobalt modified ordered mesoporous carbon were found to have a surface area of 490.06m...

msu-s mesoporous catalyst with [sio2]/[al2o3] ratio of 55 was synthesized using tetrapropylammonium hydroxide (tpaoh) as a structure directing agent and hexadecyltrimethylammonium bromide (ctab) as a surfactant. the catalytic activity of the calcined sample was evaluated for the dehydration of methanol to dimethyl ether (dme) in a vertical fixed bed microreactor at a weight hurly space velocity...

Mesoporous nanostructures represent a unique class of photocatalysts with many applications, including splitting of water, degradation of organic contaminants, and reduction of carbon dioxide. In this work, we report a general Lewis acid catalytic template route for the high-yield producing single- and multi-component large-scale three-dimensional (3D) mesoporous metal oxide networks. The large...

Mesoporous Co3O4 nanoplates were successfully prepared by the conversion of hexagonal β-Co(OH)2 nanoplates. TEM, HRTEM and N2 sorption analysis confirmed the facet crystal structure and inner mesoporous architecture. When applied as anode materials for lithium storage in lithium ion batteries, mesoporous Co3O4 nanocrystals delivered a high specific capacity. At 10 C current rate, as-prepared me...

in this research, mesoporous silica was applied as the host of corrosion inhibitor (molybdate). the loaded mesoporous silica was dispersed in an epoxy matrix. the composite was then coated on the mild steel plate. results showed that the corrosion resistance of the scratched epoxy/mesoporous silica loaded by molybdate was better than the one without molybdate or neat epoxy. on the other hand, e...

We have prepared multifunctional magnetic mesoporous Fe-CaSiO3 materials using triblock copolymer (P123) as a structure-directing agent. The effects of Fe substitution on the mesoporous structure, in vitro bioactivity, magnetic heating ability and drug delivery property of mesoporous CaSiO3 materials were investigated. Mesoporous Fe-CaSiO3 materials had similar mesoporous channels (5-6 nm) with...
