synthesized Fe3O4@ZrO2/SO4 2- as a heterogeneous nanocatalyst and used it in one pot reaction of aldehyde and indole to obtain bis(indolyl)methane derivatives. Results: An effective method for the synthesis of bis(indolyl)methane derivatives in high yields was developed by the use of Fe3O4@ZrO2/SO4 2- as a catalyst. The synthesis of bis(indolyl)methane by this catalysts resulted in short reaction times and
