Abstract: Three-dimensional (3D) porous thin films of AuPd and AgPd foams comprised of nanodendrites possess superior catalytic activity for the production of high-quality H2 from formic acid decomposition at room temperature. The high catalytic activity was attributed to the presence of abundant active sites like steps, corners, kinks and edges in the nanodendrites, and to the electronic effect. Besides the high activity, there were some more advantages for the nanodendrtic alloy foam films. For example, the foam films could be quickly electrodeposited in 5 min on a Ti substrate utilizing the template of hydrogen bubbles without needing organic additives, and it could be used directly for the hydrogen production without post-treatments. The hydrogen production was easily controllable, and we could get hydrogen and stop hydrogen production just by immersing the electrodeposited foam film into and pulling it out of the solution of HCOOH+HCOONa. The foam films could also be easily reactivated either by drying after water cleaning or by potential cycling in H2SO4 solution. |
