Thenard(1811), the discoverer of hydrogen peroxide, expected that its degradation in living tissue is performed by a special substance, which Schonbein (1863) identified as a certain kind of 'ferment'. Loew (1901) was the first who named this H2O2-degrading enzyme catalase, but it took further 22 years until Warburg (1923) demonstrated that the active center of catalase contains iron, as concluded from the characteristic inhibition with cyanide.

过氧化氢的发现者Thenard ，希望活体组织中过氧化氢的降解是由一种特殊物质引起的，Schonbein定义这种特殊物质为某种酵种，Loew是第一个定义为过氧化氢降解酶，22年后Warburg 证明过氧化氢酶的活性中心含有Fe，正如从已知氰化物的特性得到结论。1927年，WIeland提出了一个简单的细胞过中氧化氢酶的解释。
