Two‐Stage Catalytic Conversion of Carbon Dioxide Into Aromatics Via Methane

Angewandte Chemie, EarlyView.
The development of a two‐stage process for converting CO2 via CH4 to C6H6 using a Ni/TiO2 catalyst in stage 1 and a Mo/ZSM‐5 catalyst stage 2. Thermodynamic calculations as well as experimentally varying parameters, aided in finding the optimal reaction conditions and reducing the coke deposition in stage 2.
