Here, we have successfully structured Pt NPs on stress-induced to shrink ZIF-8 derived hollow Fe-NC supports, and the obtained Pt@Fe-NC catalyst enhanced ORR performance due interaction between supports leading reduced adsorption of *OH intermediates.
Exploiting advanced electrocatalysts for the sluggish oxygen reduction reaction (ORR) of cathode is greatly crucial proton-exchange membrane fuel cell (PEMFC) commercial application but still exhibit a significant challenge, especially stability issues that have drawn attractive attention. Therefore, we introduced nitrogen-doped carbon layer into Pt/C surface, which not only prevents aggregation Pt nanoparticles also endows electrocatalyst with enhanced performance without hiding internal...
Abstract Improving the activity and stability of Pt‐based electrocatalysts is essential for large‐scale commercial applications fuel cells. The ordered alloy nanomaterials encapsulated by coating have attracted significant attention. Here, we displayed a surface strategy to synthesize structurally PtCo catalysts featuring nitrogen‐doped carbon (NC). Experimental results reveal that sample with appropriate dopamine feeding content shows enhanced oxygen reduction stability, which exhibits mass...
Abstract The high cost and deficiency of long‐term durability carbon supported Pt catalysts have been regarded as obstacle that impeding their practical proton exchange membrane fuel cells (PEMFCs) technologies. Furtherly, iron nitrogen co‐doped carbons (Fe/NC) are emerging a steady electrocatalyst. Unfortunately, there less‐active sites in acidic electrolyte. Herein, combining the advantages Fe/NC catalysts, we propose an in‐situ surfactant‐free self‐templating solution reduction strategy...
The designs of efficient and inexpensive Pt-based catalysts for methanol oxidation reaction (MOR) are essential to boost the commercialization direct fuel cells. Here, highly catalytic performance PtFe alloys supported on multiwalled carbon nanotubes (MWCNTs) decorating nitrogen-doped (NC) have been successfully prepared via co-engineering surface composition electronic structure. Pt1 Fe3 @NC/MWCNTs catalyst with moderate Fe3+ feeding content (0.86 mA/mgPt ) exhibits 2.26-fold enhancement in...
The preparation of low-cost, high-activity, and high-stability platinum (Pt)-based oxygen reduction reaction (ORR) catalysts is the key to large-scale commercial application proton exchange membrane fuel cells. Herein, we designed a facile synthesis strategy achieve direct transformation solid Pt nanoparticles into hollow PtNi alloy nanocubes through eutectic salt-mediated pyrolysis nanoscale Kirkendall effect. This distinctive structure makes inner exterior spaces easy access, which would...
