 | Effect of graphene templated fluorides of Ce and La on the de/rehydrogenation behavior of MgH2 Original Research Article International Journal of Hydrogen Energy, Available online 23 June 2017, Pages Pawan K. Soni, Ashish Bhatnagar, M.A. Shaz, O.N. Srivastava
Graphical abstractThe present study suggest that in contrast to stand alone additive (ie. CeF4 and LaF3), Gr templated additive (i.e. CeF4@Gr and LaF3@Gr) shows improved hydrogen sorption in MgH2. Lower desorption temperature (245 °C) and dual tuning effect, i.e. lowering of thermodynamic (62.77 kJ/mol H2: lower from 74 kJ/mol for pristine MgH2) and kinetics barrier (93.01 kJ/mol) has been observed for MgH2 ball milled with CeF4@Gr (MgH2:CeF4@Gr). Additionally, MgH2:CeF4@Gr shows good reversibility up to 24 cycles of de/rehydrogenation. The feasible working mechanism of CeF4@Gr as additive for MgH2 has been studied in detail with the help of Transmission Electron Microscope (TEM), Fourier Transform Infrared Spectroscopy (FTIR) and X-ray Diffraction characterizations (XRD).Image 1
