Cerium promoted ni/mgo catalyst for glycerol reforming

Hydrogen (H2) has been considered as energy of future to substitute fossil fuel utilization. It is currently produced from hydrocarbon reforming (i.e. natural gas and petroleum) and electrolysis processes. Therefore, in the current work, magnesium oxide (MgO)-supported Ni catalyst with Cerium, Ce as...
