An approach for the direct synthesis of hydrogen peroxide with CO2 as solvent has been explored. Both batch and continuous experiments have been performed. The activity of self-prepared Pd-supported catalysts has been verified leading to high productivity of up to 132 g(H2O2) g(Pd)(-1) h(-1) in batch with selectivities of up to 70%. However, the use of dense CO2 in batch set back catalyst activity leading to the formation of H2O as the only product. For the continuous process in dense CO2 increased performance in terms of productivity with up to 26 g(H2O2) g(Pd)(-1) h(-1) with low selectivity were achieved. (C) 2013 Elsevier B.V.
