Synthesis of nanoporous graphene oxide adsorbents by freeze-drying or microwave radiation: Characterization and hydrogen storage properties
Kostoglou, N.; Tzitzios, V.; Kontos, A. G.; Giannakopoulos, K.; Tampaxis, C.; Papavasiliou, A.; Charalambopoulou, Georgia; Steriotis, T.; Li, Y.; Liao, K.; Polychronopoulou, K.; Mitterer, C.; Rebholz, Claus (2015)In the present work, we synthesized and systematically characterized two novel graphene-based nanomaterials, a chemically reduced graphene oxide (GO) sponge and a microwave-exfoliated GO. Textural properties were determined ...
