Iron-based catalyst, preparation method thereof and application of iron-based catalyst in heterogeneous catalytic oxidation treatment of organic waste gas

The invention relates to an iron-based catalyst, a preparation method thereof and application of the iron-based catalyst in heterogeneous catalytic oxidation treatment of organic waste gas. The iron-based catalyst comprises a MnO2 solid carrier and a catalyst active component loaded in the MnO2 solid carrier; the catalyst active components comprise Ag and Fe. The catalyst active component takes a metal salt solution as a precursor substance and is loaded on the carrier through an impregnation method. The catalyst provided by the invention solves the problems of easy loss of iron ions, easy imbalance of catalyst component proportion, low catalyst activity at room temperature, easy hardening of the catalyst and the like in the existing commercial iron-based catalyst for heterogeneous catalytic oxidation. The catalyst can be applied to the scene of organic waste gas heterogeneous catalytic oxidation treatment for a long time. 本发明涉及一种铁基催化剂及其制备方法以及在多相催化氧化处理有机废气中的应用。所述铁基催化剂包括MnO2固体载体和负载于所述MnO2固体载体中的催化剂活性成分；所述催化剂活性成
