Graphene Functionalized Mesoporous Mn and Ti Oxides for Supercapacitors

Amar V., Houck J., Shende A., Shende R., South Dakota School of Mines and Technology, US

In this investigation, several mesoporous nanocomposites such as TiO2/MnO2, TiO2/Mn2O3, TiO2/MnO2/Mn2O3 and TiO2/MnO2/Mn2O3/MnTiO3 were synthesized using the pluronic 123 templating assisted sol-gel method. To prepare these nanocomposites, sol-A with Ti precursor and sol-B containing Mn [...]

Mesoporous Alumina Affinities for Metals as a Function of pH

Hepburn R., Fujimi Corporation, US

One important application for mesoporous alumina is as the adsorbent for retaining Molybdenum-99m in the Molybdenum/Technetium generators used for medical imaging throughout the world. In 2016, Fujimi created a novel mesoporous alumina material that could [...]

Synthesis By Two-step Growth Scheme For Fabrication of Hierarchical Micro/Nano-structured Mesoporous FePO4 Particles for High Performance Lithium-Ion Batteries

Dong B., Li G., Yang X., University of Nottingham Ningbo China, CN

Olivine lithium iron phosphate (LiFePO4) has been considered as a promising cathode material in fabrication of lithium ion battery because of its features of low cost, lower toxicity, higher stability, excellent capacity retention, extremely flat [...]

Morphology and Size Control of Mesoporous ORMOSIL Particles

Jung G.I., Kim J-S, Koo S.M., Hanyang University, KR

Mesoporous ORMOSIL particles with tailored morphology and/or controlled size were prepared by a simple two-step process. The first step, synthesis of monodisperse ORMOSIL particles with multi-layered structure, involved a one-pot process in an aqueous solution [...]

Mesoporous Zirconia Supported Nickel Catalysts for Coke Minimization in Dry Reforming of Methane

Arbag H., Dogu G., Dogu T., Mustu H., Yasyerli N., Yasyerli S., Gazi University, TR

Dry reforming of methane is a promising route for conversion of two of the most abundant greenhouse gases to syngas. Ni based catalysts are generally preferred due to low cost and good activity. However, significant [...]

Starbons® – A New Family of Bio-based Mesoporous Materials Derived from Polysaccharides

Breeden S.W., Budarin V.L., Clark J.H., MacQuarrie D.J., Green Chemistry Centre of Excellence, UK

Starches from a wide variety of sources and locations can be physically expanded giving high surface areas and mesoporosity. Heating these materials leads to a family of “Starbons” with tunable surface properties depending upon activation [...]

Template – assisted sol – gel approach to synthesize new perspective alumina based catalysts

Agafonov A.V., Vinogradov A.V., Vinogradov V.V., Institute of Solution Chemistry of Russian Academy of Sciences, RU

In this work, high stable mesoporous γ-aluminas with different pore structure were synthesized. New kinds of templates were adapted to prepare alumina based catalysts with uniform and bimodal mesopore distribution with ‘small’ and ‘large’ mesopores. [...]

Photocatalytic activity of mesoporous titanium dioxide nanoparticles under visible light irradiation

Anandan S., Ikuma Y., Kida S., Kuramoto R., Niwa K., Kanagawa Inst. of Tech., JP

Using surfactant and other chemicals, nano-template consisting of SiO2 was first prepared. Then the template was treated in titanium tetra-isopropoxide dissolved in 1-propanol to convert silicon into titanium. The product was heated in air or [...]
