CO2 was converted to synthesis gas in a microwave plasma–catalytic reactor by methane reforming at atmospheric pressure. The hybrid system used waste heat from the plasma to heat the catalyst. Conversion degrees were examined as a function of gas temperature, and the reforming efficiency of the plasma-only system was compared with that of the hybrid system. As a result, the hybrid system was shown to be more efficient under catalyst-free conditions. The use of microwave plasma alone resulted in low conversions of CO2 and CH4, which were 32.9% and 42.7%, respectively, at 3 kW microwave power. High CO2 and CH4 conversions of 87.9% and 92.9%, respectively, were achieved in the presence of catalyst at the same microwave power. At constant microwave power, catalyst addition increased the H2 and CO mass yield rates to 0.27 kg/h and 2.012 kg/h, respectively. Additionally, the H2 energy yield were 270 g/h, and 91.2 g/kWh. Thus, the developed hybrid system is well suited for efficient and economically viable CO2 reduction and synthesis gas production, paving the way for next-generation CO2 utilization and zero-emission industrial processes.

An abundant manganese complex-anchored BiOI hybrid system for CO2 photocatalytic conversion was constructed. Layered BiOI and tricarbonyl Mn bipyridyl complex with carboxyl acid groups were connected with covalent bonds and used as visible light antenna and CO2 reduction reaction centers, respectively. The covalent connection of this hybrid system benefits the transfer of electrons from the semiconductor to the Mn complex. The anchoring group (carboxyl) is the key to CO2 reduction for the direct coupling of the two units, facilitating the transfer of electrons from BiOI to the manganese complexes. The photocatalytic properties and stability of the tricarbonyl Mn–bipyridyl complex were significantly enhanced with the aid of anchored BiOI. A high turnover number ([Formula: see text]) of HCOO− formation from CO2 could be achieved using this hybrid system under visible light irradiation.
