We have investigated graphitic carbon nitride (g-C3N4) as a CO2 activating support material for heterogeneous Pd catalyst on direct synthesis of HCOOH under neutral condition. This novel support has an ability to adsorb CO2 and provide an activated form of carbonate or formate species to Pd. As a result, the activity of Pd catalysts is remarkably enhanced compared to inert support such as CNT. Moreover, Pd/g-C3N4 catalyst exhibits remarkable stability during the catalytic reaction under neutral condition, which is essential property for the practical applications. Therefore, by using g-C3N4 as a support, the enhanced activity and stability could be achieved without secondary noble metal such as gold, silver, or ruthenium. |
