“…Researchers can easily modulate thermodynamic and kinetic factors to influence the morphologies of noble metal nanocrystals by wet-chemistry synthesis. The structures of noble metal nanocatalysts can be broadly categorized into nanoparticles (NPs) [26][27][28][29][30][31][32][33], nanowires (NWs) [34][35][36][37][38][39][40], nanoribbons (NRs), nanosheets (NSs), nanoplates (NPs) and, nanocages [41], nanoframes [2,[42][43][44], etc.…”

Benefiting from the ultrahigh specific surface areas, massive exposed surface atoms, and highly tunable microstructures, the two-dimensional (2D) noble metal nanosheets (NSs) have presented promising performance for various electrocatalytic reactions. Nevertheless, the heteroatom doping strategy, and in particular, the electronic structure tuning mechanisms of the 2D noble metal catalysts (NMCs) yet remain ambiguous. Herein, we first review several effective strategies for modulating the electrocatalytic performance of 2D NMCs. Then, the electronic tuning effect of hetero-dopants for boosting the electrocatalytic properties of 2D NMCs is systematically discussed. Finally, we put forward current challenges in the field of 2D NMCs, and propose possible solutions, particularly from the perspective of the evolution of electron microscopy. This review attempts to establish an intrinsic correlation between the electronic structures and the catalytic properties, so as to provide a guideline for designing high-performance electrocatalysts.

Catalysts with a platinum-rich shell and intermetallic core are considered to be one of the most promising catalysts for the oxygen reduction reaction (ORR) in fuel cells. However, too thin of a platinum-rich shell makes the core–shell structure easy to lose. Therefore, the development of the core–shell structure with an appropriate thickness of platinum-rich shell and intermetallic core remains a huge challenge in the field of fuel cells. In this paper, PtCoN-1000/C catalyst with about 1 nm thick platinum-rich shell shows significantly enhanced ORR activity and stability in acidic electrolyte, which is superior to L10-PtCo/C and commercial Pt/C catalysts. The specific power at 0.8 V and mass activity at 0.9 V are 5.60 W mgPt –1 and 0.74 A mgPt –1, respectively. It suggests that the tensile strain and moderately thickened platinum-rich shell led by nitrogen doping can greatly improve the performance of the catalyst.
