Calibrated Co3O4 nanoparticles patterned in SBA-15 3 silicas: Accessibility and activity for CO oxidation

Irène Lopes, Anne Davidson, Cyril Thomas

The catalytic performances in CO oxidation of Co3 O4 nanoparticles patterned in the porosity of SBA-15 silicas are investigated. 10 Accessibility limitations of the reactants to the catalytic sites are clearly revealed,when the Co3O4 nanoparticles are embedded in the 11 SBA-15 pores.Despite these…

Assessing carbon or tungstates coverage of ZrO2 nanoparticles supported on MWCNT via NOx-TPD

Patrick Kelleher, Gary Haller, Sandra Casale, Christophe Méthivier, Cyril Thomas

Multi-walled carbon nanotubes (MWCNT) promoted by oxides, that are far from trivial to characterize, have emerged as promising candidates in several fields such as biosensors and catalysis. In this study the coverage of ZrO2 nanoparticles supported on MWCNT, by carbonaceous deposits or tungstates…

Additive-Free Aqueous Phase Synthesis of Formic Acid by Direct CO 2 Hydrogenation over a PdAg Catalyst on a Hydrophilic N-Doped Polymer–Silica Composite Support with High CO 2 Affinity

Shinya Masuda, Kohsuke Mori, Yasutaka Kuwahara, Catherine Louis, Hiromi Yamashita

A series of N-doped polymer containing silica (NPS) materials were synthesized via condensation reactions of 3-aminopropyltriethoxysilane (APT) and various aldehydes. These materials were assessed as supports for a PdAg alloy catalyst intended to promote the CO2 hydrogenation reaction under…

Design of Advanced Functional Materials Using Nanoporous Single‐Site Photocatalysts

Kohsuke Mori, Xufang Qian, Yasutaka Kuwahara, Yu Horiuchi, Takashi Kamegawa, Yixin Zhao, Catherine Louis, Hiromi Yamashita

Nanoporous silica solids can offer opportunities for hosting photocatalytic components such as various tetra-coordinated transition metal ions to form systems referred to as “single-site photocatalysts”. Under UV/visible-light irradiation, they form charge transfer excited states, which exhibit a…

Screening Earth Analog Exoplanets on the Basis of a Predicted Nitrogen over Phosphorus Ratio

Hervé Toulhoat

Abstract Since the first discovery in 1995, data for over 5300 exoplanets have been documented in the NASA archive, revealing a vast diversity. Identifying life-enabling analogs of the Earth among this rapidly expanding catalog is of major interest. The stability of liquid water at the planetary…

Structural and electrochemical properties of Y(Ni,Mn)3 compounds in protic ionic liquid

J Monnier, G Fedlouk, J Chan, E Kurchavova, M Turmine, V Vivier, L. Laversenne, M Mateos, F Cuevas, J Zhang

The achievable voltage of an alkaline battery is limited by the narrow electrochemical stability window of water and its service life is constrained by corrosion issues related to highly concentrated alkaline solutions. An alternative to aqueous media is the use of ionic liquid (IL)-based…
