Abstract: A series of graphene modified NiY zeolites (including rGO-NiY,h-rGO-NiY and j-GO-NiY zeolites) were synthesized through in-situ method,reduction method and dipping method,respectively.With the help of XRD,FT-IR and SEM characterizations,high crystallinity,intact skeleton structure and big particle size(~3μm) were realized and confirmed after modification.Most importantly,the graphene modified NiY zeolites can be used as cathode catalyst in microbial electrolysis cell (MEC) to separate hydrogen.The evaluation of rGO-NiY showed as follows:during 12h,the maximum current density reached to 8.10A/m2,gas production were 11.1mL (pure hydrogen:9.29mL),demonstrating the excellent catalytic activity of hydrogen evolution.
