| 摘 要： | 自从G.Schikorr提出了3Fe(OH)2=Fe3O4+2H2O+H4反应之后,相继又有不少作者对该反应进行了研究。但都认为放氢的机理是不清楚的。G.N.Schrauzer认为该反应放氢一定和Fe(OH)2在歧化过程中产生的Fe°有关,但作者并没给出任何实验证明。本文从各种不同条件对这个反应进行了研究,提出了我们的放氢机理。

| Abstract: | The chemisorption of hydrogen ions on suspensions of Fe(OH)2 causes the evolution of molecular hydrogen. The coprecipitation of Ni(OH)2 improves the yield because nickle ions stabilize the hexagonal lattice of Fe(OH)2. Mossbauer spectroscopy indicates that Ni is present also in that lattice. Glucose improves further the yield because hydrogen ions chemisor-bed on Fe(OH)2 and Ni(OH)2 may act as catalyst to shift the equilibrium of mutarotation. The regenerated hydrogen ions in solution account for the additional hydrogen evolution. |
