Self-supported interconnected Pt nanoassemblies as highly stable electrocatalysts for low-temperature fuel cells
In it for the long haul: Clusters of Pt nanowires (3D Pt nanoassemblies, Pt NA) serve as an electrocatalyst for low-temperature fuel cells. These Pt nanoassemblies exhibit remarkably high stability following thousands of ...
One-pot synthesis of cubic PtCu 3 nanocages with enhanced electrocatalytic activity for the methanol oxidation reaction
Noble metals such as platinum (Pt) are widely used as catalysts in fuel cells and other heterogeneous catalytic processes. However, there is an urgent need to develop substitutes for pure Pt catalysts to reduce the overall ...
Arrays of ultrafine CuS nanoneedles supported on a CNT backbone for application in supercapacitors
Arrays of CuS ultrafine nanoneedles supported on a carbon nanotube (CNT) backbone (CNT@CuS) are fabricated by an efficient template-engaged chemical conversion route. First, the silica coated CNTs (CNT@SiO2) are introduced ...
Sandwich-structured TiO2-Pt-graphene ternary hybrid electrocatalysts with high efficiency and stability
The practical application of low temperature fuel cells is largely hindered by the unavailability of efficient electrocatalysts with high activity and stability. A promising strategy to design highly active electrocatalysts ...
Hierarchically structured Pt/CNT@TiO2 nanocatalysts with ultrahigh stability for low-temperature fuel cells
High-stability Pt electrocatalysts have been prepared using hierarchical CNT@TiO2 structures composed of TiO2 nanosheets grafted on the CNT backbone as the support. The as-prepared Pt/CNT@TiO2 electrocatalysts manifest ...
Formation of Pt-TiO2-rGO 3-phase junctions with significantly enhanced electro-activity for methanol oxidation
TiO2 nanoparticles-decorated graphene nanosheets have been prepared by a facile hydrothermal method. After depositing Pt nanoparticles exclusively around the interface between TiO2 and rGO, the obtained Pt/TiO2@rGO ...
