Rational design and synthesis of one-dimensional platinum-based nanostructures for oxygen-reduction electrocatalysis

Fuel cells have attracted extensive attention due to their high conversion efficiency and environmental friendliness. However, wider application is limited by the poor activity cost of platinum (Pt), which widely used as cathode catalyst overcome slow kinetics associated with oxygen reduction reaction (ORR). Pt-based composites one-dimensional (1D) nanoarchitectures demonstrate great advantages towards efficient ORR catalysis. This review focuses on recent advancements in design synthesis 1D catalysts. After introducing fundamental mechanism advanced architectures, strategies (template-based template-free methods) are discoursed. Subsequently, morphology structure optimization highlighted, followed superstructure assembly using blocks. Finally, challenges perspectives innovation, design, physical characterization, theoretical investigations proposed for nanocatalysts. We anticipate this study will inspire more research endeavors nanocatalysts fuel cell application. work reviews developments nanostructures, an emphasis effect synthesis, morphologies, chemical structures performance electrocatalytic cells.
