Ru complex and N, P-containing polymers confined within mesoporous hollow carbon spheres for hydrogenation of CO2 to formate

Guoxiang Yang, Yasutaka Kuwahara, Kohsuke Mori, Catherine Louis, Hiromi Yamashita

The development of reliable catalysts with both excellent activity and recyclability for carbon dioxide (CO2) hydrogenation is challenging. Herein, a ternary hybrid heterogeneous catalyst, involving mononuclear Ru complex, N, P-containing porous organic polymers (POPs), and mesoporous hollow carbon…

Spectroscopic and Electrochemical Study of the Adsorption of [Co(en) 2 Cl 2 ]Cl on γ-Alumina: Influence of the Alumina Ligand on Co (III)/(II) Redox Potential

Vincent Vivier, François Aguey, Jeanine Fournier, Jean-François Lambert, Fethi Bedioui, Michel Che

UV−visible and Raman spectroscopies as well as electrochemical techniques have been used to characterize cis- and trans-[Co(III)(en)2Cl2]Cl (en = ethylenediamine) complexes and the γ-alumina-supported cis-Co(III) complex. It is shown that the electrochemical reduction of these complexes occurs…

The concentration of bone-related organic additives drives the pathway of apatite formation

Marc Robin, Camila B Tovani, Jean-Marc Krafft, Guylène Costentin, Thierry Azaïs, Nadine Nassif

Bone models set for studying apatite mineralization tend to use excess of organic additives and a very low concentration of collagen in the light of those described in the biological tissue. However, the activity of soluble additives during mineral deposition is highly dependent on their…

Co-Al Mixed Oxides Prepared via LDH Route Using Microwaves or Ultrasound: Application for Catalytic Toluene Total Oxidation

Eric Genty, Julien Brunet, Christophe Poupin, Sandra Casale, Sylvie Capelle, Pascale Massiani, Stéphane Siffert, Renaud Cousin

Co6Al2HT hydrotalcite-like compounds were synthesized by three different methods: co-precipitation, microwaves-assisted and ultrasound-assisted methods. The mixed oxides obtained after calcination were studied by several techniques: XRD, TEM, H2-TPR and XPS. They were also tested as catalysts in…

Development of novel anti-Kv 11.1 antibody-conjugated PEG-TiO2 nanoparticles for targeting pancreatic ductal adenocarcinoma cells

Angelica Sette, Jolanda Spadavecchia, Jessem Landoulsi, Sandra Casale, Bernard Haye, Olivia Crociani, Annarosa Arcangeli

Titanium dioxide (TiO2) has been widely used in many nanotechnology areas including nanomedicine, where it could be proposed for the photodynamic and sonodynamic cancer therapies. However, TiO2 nanoformulations have been shown to be toxic for living cells. In this article, we report the development…

Surface plasmon resonance: signal amplification using colloidal gold nanoparticles for enhanced sensitivity

Sabine Szunerits, Jolanda Spadavecchia, Rabah Boukherroub

Among all the detection methods developed for bioassays, optical-based approaches are the most popular techniques. A widely used and accepted bioanalytical technique for routine characterization of molecular recognition events at a solid interface is surface plasmon resonance (SPR) spectroscopy.…

Factors affecting the long-term stability of mesoporous nickel-based catalysts in combined steam and dry reforming of methane

K. Jabbour, N. El Hassan, A. Davidson, S. Casale, Pascale Massiani

An ordered mesoporous " one-pot " nickel-alumina catalyst (5 wt% Ni) was synthesized using the evaporation-induced self-assembly method. Compared to an impregnated and to a non-porous catalysts, the ordered "one-pot" Ni-alumina sample displayed, after in-situ reduction, the…

Chemical Preparation of Supported Bimetallic Catalysts. Gold-Based Bimetallic, a Case Study

Catherine Louis

This review focuses on the chemical methods used to prepare supported bimetallic heterogeneous catalysts, i.e., bimetallic nanoparticles deposited on a support. The review is limited to the preparation of gold-based bimetallic catalysts and moreover to bimetallic nanoparticles supported on powder…

Modification of TiO2 by bimetallic Au–Cu nanoparticles for wastewater treatment

Zibin Hai, Nadia El Kolli, Daniel Bahena Uribe, Patricia Beaunier, Miguel José-Yacaman, Jackie Vigneron, Arnaud Etcheberry, Sébastien Sorgues, Christophe Colbeau-Justin, Jiafu Chen, Hynd Remita

Au, Cu and bimetallic Au–Cu nanoparticles were synthesized on the surface of commercial TiO2 compounds (P25) by reduction of the metal precursors with tetrakis(hydroxymethyl) phosphonium chloride (THPC) (0.5% in weight). The alloyed structure of Au–Cu NPs was confirmed by HAADF-STEM, EDS, HRTEM and…

Revisiting active sites in heterogeneous catalysis: Their structure and their dynamic behaviour

Jacques C. Vedrine

This short review article aims at revisiting the description of active sites in heterogeneous catalysis on solid surfaces and their role in catalyst activity and selectivity. Special emphasis is brought to: (i) structure of the solid surface; (ii) importance of active site isolation on the surface…
