Graphical abstractPorous graphene (PG) and nitrogen-substituted PG monolayers of 3N-PG and 6N-PG exhibited excellent selectivities and high permeances as effective membranes for He separation and H2 purification from Ne, Ar, N2, CO, and CH4.

| Hydrogen Storage in N- and B-Doped Graphene Decorated by Small Platinum Clusters: A Computational Study Original Research Article Applied Surface Science, Available online 10 February 2018, Pages I-Nan Chen, Shiuan-Yau Wu, Hsin-Tsung Chen
Graphical abstractWe have performed density functional theory (DFT) calculations to investigate the hydrogen adsorption on Pt4 cluster supported on pristine, B-, and N-doped graphene sheets. Calculation results show that the doping B or N atom in the graphene could enhance the interaction between the Pt4 cluster and the supporting substrate. The B-doped graphene is predicted to be the most potential materials for hydrogen storage among these three materials.
