Cu-benzene-1, 3, 5-tricarboxylate (Cu-BTC) coating on carbon fiber paper (CFP@Cu-BTC) is synthesized by using the seed-induced hydrothermal method to improve H-2 adsorption capacity, CO2/H-2 selectivity, thermal and electrical conductivity of pure Cu-BTC. The electrical conductivity, effective thermal conductivity (ETC), CO2 and H-2 adsorption capacity of CFP@Cu-BTC composites synthesized for 3, 9, 18, and 24 h are investigated, respectively. Results show the H-2 adsorption capacity of CFP@Cu-BTC (9 h) is similar to that of pure Cu-BTC. The value of the selectivity of equimolar CO2/H-2 (18 h) is 58-209 at 0 - 100 kPa and 273.15 K. The ETC of CFP@Cu-BTC is 17-25 times higher than that of pure Cu-BTC. The electrical conductivity is 1.3 x 10(11)-1.6 x 10(11) times higher compared to that of pure Cu-BTC. The CFP@Cu-BTC composite can be used as a promising material for H-2 storage and electrodes of ultra-capacitor. (C) 2019 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
