Low-noble metal electrocatalysts are attracting massive attention for anode and cathode reactions in fuel cells. Pt transition metal alloy nanostructures have demonstrated their advantages in high performance low-noble metal electrocatalysts due to synergy effects. The basic of designing this type of catalysts lies in understanding structure-performance correlation at the atom and electron level. Herein, design threads of highly active and durable Pt transition metal alloy nanocatalysts are summarized, with highlighting their synthetic realization. Microscopic and electron structure characterization methods and their prospects will be introduced. Recent progress will be discussed in high active and durable Pt transition metal alloy nanocatalysts towards oxygen reduction and methanol oxidation, with their structure-performance correlations illustrated. Lastly, an outlook will be given on promises and challenges in future developing of Pt transition metal alloy nanostructures towards fuel cells catalysis uses.

The thermal stability of the two-dimensional surface nitrides CrN, MoN and WN has been studied on transition metal alloy surfaces. The surface nitrides are obtained by means of cosegregation of the constituents on Fe–15%Cr–N(100), Fe–3.5%Mo–N(100) and Fe–9%W–N(100) single crystals. The stability of the surface nitrides decreases in the sequence Cr>Mo>W, similar to the well-known three-dimensional bulk nitrides. All compounds exhibit 1×1 LEED structures, indicating epitaxial stabilization on the corresponding substrate surface. In a narrow temperature range T≈550°C the Fe–9%W–N(100) surface shows c (2×2) ordering of the segregated nitrogen atoms.
