Hydrogen sorption by porous materials composed of one to three elements selected from boron, carbon and nitrogen and metal modification to enhance the sorption

•Nanocarbons, BN’s and CN’s were successfully prepared through wet processes.•Their hydrogen capacity at 77K and 0.8MPa exceeded 2.34 mass% per 1,000 m2 g-1.•While Pd-modification did not enhance hydrogen sorption, Pt-modification substantially did.•Ni increased hydrogen capacity of nanocarbons orig...
