Abstract

This study presents the synthesis, characterization, and catalytic performance of palladium (Pd) supported on activated carbon (AC) for the hydrolysis of ethylenediamine bisborane (EDAB). Activated carbon (AC) derived from the Paulownia tree was used as the support material, with Pd metal (5 wt%) loaded via the impregnation-reduction method. The hydrolysis reactions were conducted at 50 °C and 70 °C with EDAB concentrations of 0.02 and 0.03 M. Compared to our previous study on a bimetallic catalyst Pd-Co/AC, the monometallic Pd/AC catalyst achieved higher hydrogen generation rates (HGR), reaching a maximum of 516.9 ml/min·gcat at 70 °C for 0.03 M initial EDAB concentration. Kinetic analysis determined the activation energy as 23.14 kJ/mol. Characterization techniques, including FTIR, SEM-EDX, BET, XRD, and XPS, confirmed the structural and chemical properties of the synthesized catalyst.
