Junqing Yan, Yujin Ji, Lingqiao Kong, Youyong Li, Miriam Navlani-García, Shengzhong Frank Liu, Yasutaka Kuwahara, Kohsuke Mori, Michel Che, Hiromi Yamashita

Although black phosphorus (BP) is an interesting 2D nanosheet material with a high hole mobility, its application in the photocatalytic water oxidation for O2 evolution is not reported yet. Herein the use of BP coupled with a reductive hydroxide, Ni(OH)2, is reported for the first time. The…

Framework Stabilization of Ge-Rich Zeolites via Postsynthesis Alumination

Ff Gao, M Jaber, K Bozhilov, A Vicente, Christian Fernandez, V Valtchev

The use of organic structure directing agents in zeolite syntheses has dramatically extended the number of zeolite structure types during the past decades. However, for about 20% of all known zeolite structure types, the necessary postsynthesis elimination of organic templates by high-temperature…

UHV Deposition of the Gly-Pro Dipeptide on Cu(110) by Sublimation or Electrospray Ionization

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

While most of the peptide adsorption studies, in vacuum, are achieved by sublimation, we demonstrate here the possible use of electrospray ionization (ESI) to deposit entire peptides, possibly surrounded by solvated ions, on a surface in ultra high vacuum (UHV) conditions. This paper is then…

Vanadium incorporation from aqueous NH4VO3 solution into siliceous Beta zeolite determined by NMR with formation of V-single site zeolite catalysts for application in SCR of NO

Rafal Baran, Yannick Millot, Frederic Averseng, Stanislaw Dzwigaj

The speciation of vanadium in initial aqueous NH4VO3 solutions as a function of pH and concentration, in supernatant and in wet solids were investigated by 51V static and MAS NMR. Two series of VSiBeta zeolite catalysts were prepared by a two-step postsynthesis procedure at pH = 2.5 and 6. 51V…

Factors impacting the aggregation/agglomeration and photocatalytic activity of highly crystalline spheroid- and rod-shaped TiO 2 nanoparticles in aqueous solutions

Thomas Degabriel, Elodie Colaço, Rute F Domingos, Karim El Kirat, Dalil Brouri, Sandra Casale, Jessem Landoulsi, Jolanda Spadavecchia

We investigate the characteristics, fate and photocatalytic activity of spheroid- and rod-shaped TiO2 nano-crystals in aqueous solutions to better understand their behaviour in media of biological and environmental interest. For this purpose, the potential of a solvothermal method in synthesizing…

Influence de l'incorporation du vanadium dans l'hydroxyapatite sur la réaction d'oxydation déshydrogénante du propane, Influence of the incorporation of vanadium in hydroxyapatite on the oxidative dehydrogenation of propane reaction

Sarah Petit

Dans l'objectif de combler le gap entre l'offre et la demande en propène, la réaction d'oxydation déshydrogénante du propane (ODHP) est une solution alternative à la réaction de déshydrogénation directe. Les hydroxyapatites (HAp) modifiées au vanadium sont des matériaux bi-…, In order to fill the gap between propene supply and demand, the oxidative dehydrogenation of propane (ODHP) is an alternative solution to the direct dehydrogenation process. Vanadium-modified hydroxyapatites (HAp) are bifunctional catalysts combining acid-base and redox properties which were shown…
