A first principles study on aluminium-sulfur co-doped graphene as an electro-catalyst for oxygen reduction reaction in a PEM fuel cell

Fabrication and characterization of NiCu/GO and NiCu/rGO nanocomposites for fuel cell application

“…This decrease may be caused by rGO's functional groups that include oxygen, which can cause the optical band gap to become narrow. 49 In nanomaterials with a narrower bandgap, the electrons can move from the VB to the CB more easily. This suggests increased electrical conductivity and electron concentration for NiCu/rGO.…”
