The study reports preparation, characterization, and catalytic activity of Pd0/WO3 nanoparticles in H2 evolution from dimethylamine borane (DMAB). The active catalyst called Pd0/WO3 NPs were obtained from the in situ reduction of Pd2+/WO3 precatalyst and tested in H2 releasing from DMAB. Pd0/WO3 NPs were found as remarkable catalysts providing a turnover frequency value of 948.0 h-1 in H2 releasing from DMAB at 60.0 ± 0.5 °C. The results of some advanced analytical techniques reveal that Pd0 NPs show uniform dispersion on the surface of tungsten(VI) oxide (WO3) with 5.85 ± 0.57 nm of particle size. The reducible nature of tungsten(VI) oxide improves the catalytic efficiency of Pd0/WO3 NPs in H2 generation from DMAB. Pd0/WO3 NPs were found as active catalysts even after the 6th run of dehydrogenation reaction. The report also covers the kinetic performance of the catalyst.
