“…[22] In comparison with the partially ordered fct-PtFe NPs and disordered fcc-PtFe NPs, the fully ordered fct-PtFe NPs showed considerably higher mass activities towards both ORR and HER in acidic electrolyte (Figure 4d), along with much enhanced stability during the ADT. [21] In addition to the above mentioned strategies, several other approaches have been proposed to address the aggregation/ sintering problem during the high temperature induced disorder-order phase transition process, including direct synthesis of ordered structures in liquid phase using microwave heating method, [23] hafnium oxide [24] or iron oxide coating, [25] mixing with NaCl powders, [26] stabilizing by linker molecules [27] and biomolecule-assistant NPs growth. [28] As each method holds its advantages as well as limitations, the selection of the method is therefore highly dependent on its practical applications.…”

Ordered intermetallic alloys have attracted extensive attention as advanced electrocatalysts for polymer electrolyte membrane fuel cells (PEMFCs) reactions with much improved activity and stability. Here, latest progress in tuning intermetallic Pt‐ and Pd‐based nanocrystals with tunable morphology and structure for catalyzing both the cathodic reduction of oxygen and anodic oxidation of fuels (e.g., methanol, ethanol and formic acid) in PEMFCs is highlighted. Making/tuning interesting intermetallic PtM (M = Fe, Co, Pb, Cu, etc.)‐based nanocrystals for boosting oxygen reduction reaction with high activity and stability by using/controlling high‐temperature annealing treatment is discussed. In all the reported Pt‐based intermetallic nanocrystals, controlling the degree of ordering under the proper high temperature treatment is the key for achieving the optimized electrocatalysis. In order to search for cheaper catalysts, the progress on making Pd‐based intermetallic nanocrystals is also discussed. Furthermore, future research directions are proposed and discussed to further enhance the efficiency of such unique intermetallic multimetallic nanocatalysts. This report aims to demonstrate the potential of ordered intermetallic strategy for boosting electrocatalysis and stimulating more research efforts in this field.

This paper reviews recent advances in chemical synthesis, self‐assembly, and potential applications of monodisperse binary FePt nanoparticles. After a brief introduction to nanomagnetism and conventional processes of fabricating FePt nanoparticles, the paper focuses on recent developments in solution‐phase syntheses of monodisperse FePt nanoparticles and their self‐assembly into nanoparticle superlattices. The paper further outlines the surface, structural, and magnetic properties of the FePt nanoparticles and gives examples of three potential applications in data storage, permanent magnetic nanocomposites, and biomedicine.
