“…The concept of tandem catalysis for the hydrogenation of CO/CO 2 to value-added fuels or products, such as low-carbon olefin [ 114 , 115 , 116 , 117 ], aromatic, gasoline, and alcohol, has drawn the attention of many researchers [ 38 , 118 , 119 ]. For example, a high aromatic selectivity can be achieved by combining the methanol synthesis catalyst with the aromatization zeolite catalyst [ 120 , 121 , 122 , 123 , 124 , 125 , 126 ].…”
