La‐Based Perovskites Combined with HZSM‐5 for Selective Conversion of Syngas into Aromatics

Fe was embedded in perovskite lattice and combined with HZSM-5 to produce LaFeO3/HZSM-5 bifunctional catalyst, which showed an excellent catalytic performance with CO conversion of 28.5 % and aromatics selectivity of 82.0 %. The composition of B-site metals in perovskites and its stabilization in the structure are essential for activity of syngas to aromatics (STA) reaction. In situ DRIFTs study revealed the syngas conversion over perovskite followed the surface formate and methoxy intermediate species transformation pathway.
