Method for preparing high-dispersion partially disordered platinum-zinc intermetallic compound material by confinement pyrolysis strategy

The highly dispersed partially disordered platinum-zinc intermetallic compounds were prepared through the domain-limited pyrolysis strategy, which solved the problem of reduced stability of the platinum-based alloy catalyst during the acid cycle and the unsatisfactory hydrogen evolution reaction activity caused by zinc-hydrogen repulsion properties, and achieved improvement of catalytic activity and stability.

Abstract

The invention aims to provide a method for preparing a high-dispersion partially disordered platinum-zinc intermetallic compound material by a confinement pyrolysis strategy, and belongs to the technical field of electrolyzed water catalysts, and nitrogen-containing porous cavities and a small amount of zinc are generated by pyrolyzing a zinc-containing metal organic framework material. The platinum atoms are then confined by nitrogen coordination and narrow pores inherited from the precursor. As zinc and platinum coexist in a limited space, the limited rearranged platinum-zinc intermetallic compound material is obtained through simple pyrolysis. The strategy not only avoids complex interface adjustment between the organic precursor and the inorganic precursor, but also provides a universal way for constructing the limited metal alloy.
