Recently, electrochemical CO2 reduction reaction (CO2RR) is a highlighted research field to utilize CO2 as a valuable chemical resource. We present the new and highly efficient non-noble metal catalyst (Co-PPy-C), which is a hybrid form of metal (Co) and organic polymer (polypyrrole), to convert CO2 to CO. Co-PPy-C reduced CO2 to CO electrochemically with high selectivity at low overpotential region. The metal mass activity for CO production was one of the highest values among the previously reported catalyst based on the noble metal nanoparticles. Fisher-Tropsch synthesis (FTS) is a heterogeneous catalytic process that converts syngas (CO+H2) into clean hydrocarbon products. Here, we presnt a simple method to synthesize Ru nanoparticles confined in the nanochannels of OMAS (Ru@OMAS). The Si/Al-50 shows the highest selectivity (63.6%) for liquid fuels (C5-C20) and excellent FT activity (CO conversion of 47.8%) due to its mild acidity and relatively good reducibility. |
