Lipase-embedded Silica Nanoparticles with Oil-filled Core-Shell Structure: Stable and Recyclable Platforms for Biocatalysts

Yasutaka Kuwahara, Takato Yamanishi, Takashi Kamegawa, Kohsuke Mori, Michel Che, Hiromi Yamashita

Lipase enzyme was embedded within silica nanoparticles with oil-filled core-shell structure. The enzyme embedded within such architecture retained all of its activity and showed high catalytic performance both in water and in organic media with optimal stability and recyclability.

Identification of the silver state in the framework of Ag-containing zeolite by XRD, FTIR, photoluminescence, 109 Ag NMR, EPR, DR UV-vis, TEM and XPS investigations

Nataliia Popovych, Pavlo Kyriienko, Sergiy Soloviev, Rafal Baran, Yannick Millot, Stanislaw Dzwigaj

Silver has been identified in the framework of AgxSiBEA zeolites (where x = 3–6 Ag wt%) by the combined use of XRD, 109Ag MAS NMR, FTIR, diffuse reflectance UV-visible, EPR and XPS spectroscopy. The incorporation of Ag ions into the framework of SiBEA zeolite has been evidenced by XRD. The…

Ruthenium sulfide clusters in acidic zeolites: in situ XAS characterization during sulfidation and reaction

Juliette Blanchard, Kyoko K. Bando, Takashi Matsui, Masaru Harada, Michèle Breysse, Yuji Yoshimura

In situ XAS at the Ru K edge was used to study the reductive sulfidation (15% H2S/H2) of Ru(NH3)63+ supported on HYd zeolite, and the evolution of the sulfided sample under working conditions (lower H2S partial pressure, addition of toluene to the feed). Sulfidation starts at room temperature and…

Using Prussian blue analogue nanoparticles confined into ordered mesoporous silica monoliths as precursors of oxides

Virgile Trannoy, Émilie Delahaye, Giulia Fornasieri, Patricia Beaunier, Anne Bleuzen

Powdered Prussian blue analogues (PBAs) and PBAs confined in ordered mesoporous silica monoliths were used as oxide precursors through thermal treatment under an oxidizing atmosphere. The study focuses on the transformation of the alkali cation-free CoCo PBA of chemical formula K0.1CoII4[CoIII(CN)6…

Coordination chemistry approach for the end-to-end assembly of gold nanorods

P.R. Selvakannan, Eddy Dumas, Frédéric Dumur, Christine Péchoux, Patricia Beaunier, Arnaud Etcheberry, Francis Secheresse, Hynd Remita, Cédric Mayer

Gold nanorods synthesized by radiolysis were selectively end-functionalized by a fully conjugated thiol bearing a pendant terpyridine group; addition of ferrous ions led to the end-to-end 1D self-assembly of the nanorods. Similar results have been obtained when the preformed [(HStpy)Fe(tpySH)](2+)…

Development of novel cathode materials for the bioelectrocatalysis of oxygen reduction reaction by laccase from Trametes versicolor

Achraf Blout, Alain Pailleret, Claude Jolivalt

Biocatalysts such as enzymes or bacteria constitute an attractive alternative to transition metal catalysts. They have several advantages as they often possess a better selectivity and higher catalytic performances and they can be used in different types of electrochemical devices such as fuel…

Rh-Ni/SBA-15 prepared by two solvents method as stable catalysts for the dry reforming of methane at high pressure

M.N. Kaydouh, El Hassan N., Elzakhem H., Anne Davidson, Sandra Casale, Pascale Massiani

The effect of Rh addition on the catalytic performance of Ni/SBA-15 catalysts was studied in the dry reforming of methane. The SBA-15 silica support was synthesized in large quantities and the metals were deposited using the two solvents impregnation method. The properties of the calcined, reduced…

“Water soluble” palladium nanoparticle engineering for C–C coupling, reduction and cyclization catalysis

A. Iben Ayad, C. Belda Marín, E. Colaco, C. Lefevre, C. Methivier, A. Ould Driss, J. Landoulsi, Erwann Guénin

The use of Pd nanoparticles (Pd-NPs) to realize several important organic reactions allows efficient catalysis with low metal loading (<1000 ppm), hence providing a greener catalytic system. However, to be truly green Pd-NPs need to be synthesized in a sustainable manner and be able to react…
