![]() ![]() The latter exhibit greater redox ability of the manganese species and a higher density of active surface oxygen species with respect to the perovskite precursor. In the light of the experimental results, such performances can be related to the formation of a meso/macro-porous structure conferring high surface area and good accessibility of the active surface sites.

Superior catalytic properties of ε-MnO 2 were observed toward HCHO oxidation as well as a good catalytic stability with respect to other macro-mesoporous counterparts.

In our case, this soft process allowed us to obtain the ε-MnO 2 phase with hierarchical porosity without any template. Bruce Rochard (1) Carol Rochard (1) Christelle Rochard (1) Darren Rochard (1) David Rochard (1) Dean Rochard (1) Emma Rochard (1) Guillaume Rochard (1). By Guillaume Rochard, Christophe Poupin, Rebecca El Khawaja, Eric Genty Wiley Online Library Verified Graphical Abstract This study examines the influence of the Mn/Mg ratio on the physicochemical properties and catalytic activity of MnxMg6-xAl2-O catalysts. Specifically, extending the acid etching duration promotes the surface area and pore volume of the materials while developing interconnected macro-mesoporous networks. Strength and oxidizing properties of the acid used as modifying agent strongly impact textural and redox surface properties of the resulting materials. Jeanne was born on February 22 1743, in Martigné-Briand, Maine-Et-Loire. Guillaume Rochard Sebastien Royer Activated Reactive Synthesis, as a top-down synthesis approach, is proposed for the production of nanocrystalline, high surface area, manganese (IV) oxide. Guillaume was born on October 2 1741, in Thouarcé, Maine-Et-Loire. This transformation proceeds through a soft-chemical process involving the dissolution of trivalent lanthanum and manganese from the perovskite structure and the dismutation of Mn 3+ cations into MnO 2 and Mn 2+ species. Lille, CNRS, Centrale Lille, ENSCL, Univ. François Nicolas ROCHARD was born on month day 1779, in birth place, to Guillaume Louis Augustin ROCHARD and Jeanne LEBRETON. The LaMnO 3 transformation was fully investigated using ICP, XRD, N 2 physisorption, TPR, TPD, SEM, TEM/EDS and XPS. 2021 Catalytic total oxidation is an efficient technique for. ![]() A simple template-free method, based on a mineral acid etching process using manganite perovskite (LaMnO 3) as precursor, was successfully developed to obtain a series of 3D meso/macro-porous materials. A New Etching Environment (FeF3 /HCl) for the Synthesis of Two-Dimensional Titanium Carbide MXenes: A Route towards.
