Deciphering interfacial capacitance of passive electrode : contribution of the double layer

Oumaïma Gharbi, Mai T.T. Tran, Mark E Orazem, Bernard Tribollet, Mireille Turmine, Vincent Vivier

The analysis of the EIS response of passive film remains a difficult challenge since it usually results in a non-ideal behavior of the dielectric properties of the film and mainly relies on the assumption that the contribution of the double layer can be neglected. The later an approximation can be…

Electrochemical and spectroscopic evidences of corrosion inhibition of bronze by a triazole derivative

Ahmed Dermaj, Najat Hajjaji, Suzanne Joiret, Kamal Rahmouni, Abdellah Srhiri, Hisasi Takenouti, Vincent Vivier

The electrochemical behavior of the bronze (Cu–8Sn in wt%) was investigated in 3% NaCl aqueous solution, in presence and in absence of a corrosion inhibitor, the 3-phenyl-1,2,4-triazole-5-thione (PTS). The inhibiting effect of the PTS was evidenced for concentrations higher than 1 mM for the…

Biomass characterization and biogas production of pretreated straw: is there a correlation?

Vincenzo Calcagno, Shruthi Meenakshisundaram, Claire Ceballos, Antoine Fayeulle, Estelle Léonard, Virginie Herledan, Jean-Marc Krafft, Yannick Millot, Claude Jolivalt, André Pauss, Xiaojun Liu

Lignocellulosic biomass is a very attractive substrate for biogas production via anaerobic digestion. Among all, straw represents a very interesting and worldwide diffused agricultural by-product. However, due to the intrinsically complex structure of lignocellulosic biomass, straw has low…

Au-Modified Pd catalyst exhibits improved activity and stability for NO direct decomposition

Taha Elgayyar, Josefine Schnee, Alain Tuel, Laurence Burel, Francoise Bosselet, Yves Schuurman, Frederic C Meunier, Laurent Delannoy, Cyril Thomas

The direct decomposition of NO x at moderate temperatures is a challenge because of the poisoning of the surface of noble metals by oxygen, yet the modification of Pd with Au enables obtaining a highly stable catalyst under an O 2-free feed at 450°C. Care was taken to ensure that the reaction was…
