Problems solved by technology

As documented (S.J.Gao, S.Y.Hao, Z.N.Huang, et al.Synthesis of high-entropy alloy nanoparticles on supports by the fast moving bed pyrolysis[J].Nature Communications,2020,11(1).), mixed metal chloride The compound precursor is pyrolyzed and supported on carbon black, graphene oxide, γ-Al 2 o 3 and zeolite and other granular carriers, within 5s the metal precursor (propelled at a speed of 20cm s -1 ) is rapidly raised to 923K, while the temperature of the heating zone is lowered to 920K, which can ensure the simultaneous pyrolysis of mixed metal precursors, due to the rapid reaching of high temperature (higher than the pyrolysis temperature of all precursors), thus forming high-entropy alloy nanoparticles, However, the pyrolysis and loading process is relatively complicated, which brings difficulties to the rapid temperature rise synthesis
[0012] In summary, the technical defects of the above preparation method of poly-element nanoparticle materials are: complex process, difficult operation and long time, and the synthesized poly-element nanoparticles are not stable when exposed to air, etc.
These disadvantages limit the production of polyelemental nanoparticles

Description

technical field [0001] The invention belongs to the technical field of polyelement nanoparticles. In particular, it relates to a strongly stable light-limiting five-member polyelement nanoparticle and a preparation method thereof. Background technique [0002] Poly-element nanoparticles have excellent catalytic performance and ultrafast optical response due to their new morphological structure, and have broad application prospects in the fields of catalysis, energy storage, biology, and plasmonics. The current method of preparing low-entropy alloy nanoparticles is wet chemical synthesis, which can obtain various particle sizes, shapes and phases, but the alloy composition of the wet chemical synthesis method does not exceed three elements, which limits the number of its element types and makes the alloy material impossible. to a higher level of application.
