Several types of catalysts are employed in CO2RR, including:
1. Metal-based Catalysts: These include copper (Cu), silver (Ag), gold (Au), and zinc (Zn). Copper is particularly notable for its ability to produce a wide range of hydrocarbons and oxygenates. 2. Metal Oxides: Such as titanium dioxide (TiO2) and iron oxide (Fe2O3), which are often used due to their stability and activity. 3. Molecular Catalysts: Including metal complexes and enzymes, which offer high specificity for certain products. 4. Hybrid Catalysts: Combining different materials to enhance performance and selectivity.
