Development of a tubular continuous flow reactor for the investigation of improved gas–solid interaction in photocatalytic CO 2 reduction on TiO 2

A self-made, low-cost tubular reactor for the gas-phase photo-catalytic CO 2 reduction was developed. The resulting flow conditions cause an intensive interaction between the reactants in the gas-phase and the fixed bed photocatalyst. This approach is used to test the scalability of tubular reactors for the photocatalytic CO 2 reduction.
