The effects of the particle composition (either palladized-Fe bimetallic or isolated Pd and Fe nanoparticles) on dechlorination (figure a) and H2 production (figure b). This study conducted in a solution phase (CMC is 0.5 wt%, [Fe] = 500 ppm, [PCB 1]o = 5 ppm. T = 23 °C, pH = 7.8). The H2 production at different Pd contents, in 10 min, was normalized with the production at 0% Pd batches.
