Abstract

The synthesis of heteroatom (P)-doped porous carbon derived from the paste of newly growing Indian banyan tree (Ficus benghalensis) is described. The synthesis involves activation, carbonization and phosphorous-doping processes using H3PO4 as activating agent and as phosphorous source. The phosphorous-doped porous carbon material shows a wafer-like morphology with specific surface area of 1406 m2/g. This material exhibits hydrogen storage capacity of ∼1.2 wt% at 298 K and 100 bar. This easily prepared carbon material is promising for realistic hydrogen storage.
