Abstract

The invention discloses a Pd-based transition-metal-doped binary nano-porous material and a preparation method thereof. The Pd-based transition-metal-doped binary nano-porous material is prepared by taking metal glass (PdM)80P20 prealloy as a raw material and dealloying in a solution by adopting a tri-electrode device, wherein M is Ni, Cu, Co or Fe; and the Pd-based transition-metal-doped binary nano-porous material has an internally-communicated doublet aperture structure, wherein the macropore size in nanopores is 70-100nm and the micropore size in the nanopores is 3-5nm, and the communicated metal ligament tissue width is 10-20nm. According to the Pd-based transition-metal-doped binary nano-porous material, transition metal doping of the Pd-based nano-porous material is easy to realizeby adopting a method of taking the metal glass as the prealloy, and the doped element content can be adjusted according to using requirements.

Description

technical field

[0001] The invention relates to a method for preparing a nanoporous material for catalysis, chemical sensing and biological filtration, provides a Pd-based transition metal-doped binary nanoporous material, and belongs to the technical field of nanomaterial preparation.

[0002] Background technique

[0003] Nanoporous materials belong to the category of nanoscience and technology. Among them, nanoporous Pd has excellent properties such as large specific surface area, small mass, and good electrical and thermal conductivity, and has been widely used in the fields of catalysis, chemical sensing, and biological filters.

[0004] Unlike natural materials such as bone, rock and soil, all nanoporous metal materials need to be synthesized artificially. The current synthesis methods mainly include foaming method, template method, self-assembly and dealloying method. Among them, the dealloying method is to use the difference in metal activity among the group me...
