dc.description.abstract | The iron oxide photoanode was modified with a graphene-carbon nanotube (CNT) composite conducting scaffold for efficient charge transfer from Fe2O3 particles to transparent conducting oxide substrate in photoelectrochemical water splitting cells. The Fe2O3-composite photoanode showed a photocurrent increase of 530% compared with to the bare Fe2O3 photoanode at 1.23 V vs. RHE, while the increase was only 200 and 240% for Fe2O3-CNT and Fe2O3-graphene photoanodes, respectively. This remarkable performance enhancement by the composite scaffold was attributed to synergistic effects induced by the formation of a 3D-like architecture from 1D CNT and 2D graphene. They become a spacer for each other forming a more open and highly exposed structure, in which both 2D graphene and 1D CNT can exist in the forms with much less self-agglomeration, thus not only enlarging the contact area between the conducting scaffold and Fe2O3 particles but also recovering in part the intrinsic conducting ability of graphene and CNT. | - |
