Synthesis and characterization of EFB clinker supported nickel and cobalt catalysts for methane dry reforming

Methane dry reforming is environmental friendly due to the potential sequestration of CO2. Therefore, substantial research works have been carried out to develop reforming catalysts that exhibit high catalytic performance and excellent longevity. The current work reports on the synthesis of 20wt%Co/...
