Various MOFs with tailored nanoporosities have recently been developed as potential storage media for CO 2 and H 2 . The composites based on Cu-BTC and graphene layers were prepared with different percentages of graphene oxide (GO). Through the characterization analyses and gas adsorption experiments, we found that the nanosized and well-dispersed Cu-BTC induced by the incorporation of GO greatly improved the carbon dioxide capture and hydrogen storage performance of the composites. The materials obtained exhibited about a 30% increase in CO 2 and H 2 storage capacity (from 6.39 mmol g À1 of Cu-BTC to 8.26 mmol g À1 of CG-9 at 273 K and 1 atm for CO 2 ; from 2.81 wt% of Cu-BTC to 3.58 wt% of CG-9 at 77 K and 42 atm for H 2 ). Finally, the CO 2 /CH 4 and CO 2 /N 2 selectivities were calculated according to single-component gas sorption experiment data.

PdZn alloy NPs encapsulated within a few layers of graphene exhibit enhanced acetylene selectivity and robust long-term stability in selective hydrogenation of acetylene, compared with that of traditional supported Pd and PdZn alloy catalysts.
