Enhancement of water remediation by innovative photocatalytic luminous textiles reactor: Performance, kinetic modeling, and mechanistic insights

Sarra Karoui, Aymen Amine Assadi, Achraf Ghorbal, Lotfi Khezami, Achraf Assadi, Sivachandiran Loganathan, Abdeltif Amrane

To address wastewater treatment, a photocatalytic process using luminous-textile has been proposed due to its high efficiency and non-toxicity. In the present work, the photodegradation of Ciprofloxacin (CIP) in the liquid phase was studied in a compact reactor with a luminous-textile catalyst in…

On an additional promoting role of hydrogen in the H2-assistedC3H6-SCR of NOxon Ag/Al2O3: A lowering of the temperature offormation-decomposition of the organo-NOxintermediates?

Cyril Thomas

tThe addition of minute amounts of H2to the selective catalytic reduction of nitrogen oxides (NOx)by hydrocarbons (HC-SCR) has been shown to promote the reduction of NOxat remarkably lowerreaction temperatures on Ag/Al2O3catalysts. Despite extensive investigations, the origin of this remark-able…

Insights into the influence of the Ag loading on Al2O3 in the H2-assisted C3H6-SCR of NOx

Tesnim Chaieb, Laurent Delannoy, Guylène Costentin, Catherine Louis, Sandra Casale, Ruth L. Chantry, Z.Y. Li, Cyril Thomas

The addition of H2 has been reported to promote drastically the selective catalytic reduction of NOx by hydrocarbons (HC-SCR). Yet, the influence of the Ag loading on the H2-promoted HC-SCR has been the subject of a very limited number of investigations. The H2-HC-SCR earlier studies reported…

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…

Role of oxygen vacancies in the basicity of ZnO: From the model methylbutynol conversion to the ethanol transformation application

C. Drouilly, J.M. Krafft, F. Averseng, H. Lauron-Pernot, Delphine Bazer-Bachi, Céline Chizallet, V. Lecocq, Guylène Costentin

The parameters governing the basic reactivity of kadox and ex-carbonate zinc oxide samples towards alcohol conversion were investigated varying the atmosphere of pre-treatment for a model reaction, the methylbutynol (MBOH) conversion, and the ethanol conversion reaction, a transformation of…

Maghemite nanoparticles and maghemite/silica nanocomposite microspheres as magnetic Fenton catalysts for the removal of water pollutants

Nassira Ferroudj, Jimmy Nzimoto, Anne Davidson, Delphine Talbot, Emmanuel Briot, Vincent Dupuis, Agnès Bée, Mohamed Salah Medjram, Sébastien Abramson

Maghemite nanoparticles (-Fe 2 O 3 NP) and maghemite/silica nanocomposite microspheres (-Fe 2 O 3 /SiO 2 MS) have been evaluated as magnetic heterogeneous Fenton catalysts. The catalysts were fully characterized by electronic microscopies, magnetometry, XRD, UV–vis–NIR spectroscopy, and sorption…

Non-destructive investigation of fibronectin adsorption on titanium surfaces using PM-RAIRS: effect of surface hydroxylation

Stéphanie Boudesocque, Olivier Dargaud, Lorenzo Stievano, Christophe Méthivier, Jean-Francois Lambert, T. Coradin, Claire-Marie Pradier

Polarisation-modulation reflection-absorption infrared spectroscopy (PM-RAIRS) is a useful non-destructive technique to study semi-quantitatively the adsorption of proteins on metal surfaces. In this work, we employed PM-RAIRS to study the effect of the degree of hydroxylation of the surface of…
