We investigate the influence of MnO2 polymorphism form on MnO2/Ag2O hydrogen getter. The results show that the performances strongly depend on the polymorphism form of manganese oxide. The nsutite gamma-MnO2 phase, which consists of a random intergrowth of MnO2-ramsdellite and MnO2-pyrolusite building blocks, shows the more promising performances to trap H-2 via the formation of hydroxyl groups. This observation is especially relevant for compounds with a low pyrolusite/ramsdellite ratio and a high rate of microtwinnings. (C) 2013 Elsevier B.V. All rights reserved.
