Fe2Zn(C2O4)4→ZnFe2O4+4CO+4CO2
亜鉛オキサラート3.2g及び鉄(III)オキサラート8.2g(モル比1:1)を蒸留水800mlに溶解させて金属前駆体水溶液810gを準備した。前記金属前駆体水溶液を、蒸発器にて70℃で、3時間の間、投入された水の総量から99重量%が除去されるまで気化させながら触媒前駆体を析出させた。
亜鉛オキサラート2.4g及び鉄(III)オキサラート9.4g(モル比1:1.5)を蒸留水800mlに溶解させて金属前駆体水溶液810gを準備した。前記金属前駆体水溶液を、蒸発器にて70℃で、3時間の間、投入された水の総量から99重量%が除去されるまで気化させながら触媒前駆体を析出させた。
塩化亜鉛1.0g及び塩化鉄(III)4.1g(モル比1:2)を蒸留水700mlに溶解させて金属前駆体水溶液710gを準備した。前記金属前駆体水溶液に3M濃度のNaOH水溶液18gを滴加して、最終溶液のpHを9に調節した。このときに生成されたスラリー状態の溶液を濾過し、蒸留水1000mlで洗浄した後、90℃で乾燥し、乾燥されたケーキ(cake)状態の触媒前駆体をエアー雰囲気で700℃で3時間焼成して、亜鉛フェライト触媒を製造した。このとき、製造された亜鉛フェライト触媒をXRDで測定して、ZnFe2O4相が形成されたことを確認した。これを図3に示した。
前記実施例2で析出された触媒前駆体を、エアー(air)雰囲気で、それぞれ300℃及び400℃で3時間焼成した以外は、実施例2と同様に行って亜鉛フェライト触媒を製造した。このとき、製造された亜鉛フェライト触媒をXRDで測定して、触媒が生成されていないことを確認した。これを図2に示した。
