“…Aika et al have studied the reaction mechanisms on Fe catalysts 4), 5) . They found that Ru catalysts supported on basic oxides with alkaline metal additives (e.g., Ru/Cs/ MgO) exhibited good activity at around 300-350 °C 6), 7) . During the last decade, several discoveries have been made concerning the support materials for supported Ru and Co catalysts.…”
