MnV 2 O 6 + δ 5 (0.5 δ 12 MnV 2 O 6.96 ) at low voltage (≈ 1 V). During the first Li insertion, Mn 4+ is first reduced to Mn 2+ and V 5+ is reduced to V 3+ . Upon further cycling, the V oxidation state varies reversibly between +3 and +5, whereas

MnV 2 O 6+δ .nH 2 O (0 < δ < 1) amorphous oxides were prepared by a two-step process including the precipitation of a crystallized precursor MnV 2 O 6 .4H 2 O and its ozonation at tempcratures below 100 °C. Their characterization by spectroscopic

Reversible lithium deintercalation of chromium-substituted spinel manganese oxides LiCryMn2 − yO4 (0 ≤ y ≤ 1) in the voltage range 3.4–5.4 V versus Li, occurs in two main steps for 0 < y < 1: one at about 4.9 V and the other at about 4 V. The

The aim of this work concerns the study of new lamellar perovskites M I (A n −1 B n O 3 n +1 ) as catalysts for the oxidative coupling of methane. The main results show that: Substitution in an octahedral site (B) strongly modifies both activity an

The oxidative coupling of methane has been studied in the presence of lamellar perovskites Bi2O2(An-1BnO3n+1) belonging to Aurivillius phases. These materials are selective and stable in the OCM reaction. Moreover, their substitution in perovskite (A

Adding sodium to lanthanum oxide increases appreciably the activity, the C+2 selectivity and the stability of the catalyst. The variations of these catalytic properties when the main kinetic parameters (contact time, temperature etc) vary could find
