Batteries and Fuel Cells

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Area of Science:

Materials Science
Electrochemistry
Catalysis

Background:

Platinum-based alloy catalysts are essential for fuel cell reactions like oxygen reduction (ORR) and methanol oxidation (MOR).
Optimizing catalyst composition and morphology is key to improving their efficiency and durability.

Purpose of the Study:

To synthesize novel platinum-cobalt (Pt-Co) nanoframes.
To evaluate the electrocatalytic performance of Pt-Co nanoframes for ORR and MOR.

Main Methods:

Synthesis of Pt-Co nanoframes through chemical etching of cobalt from solid rhombic dodecahedra.
Electrochemical testing in acidic and alkaline electrolytes to assess ORR and MOR activity and stability.

Main Results:

Pt-Co nanoframes achieved high ORR mass activity (0.40 A mg_Pt^-1 initially, 0.34 A mg_Pt^-1 after 10,000 cycles).
Pt-Co nanoframes exhibited 4-fold higher MOR mass activity (4.28 A mg_Pt^-1) compared to commercial Pt/C.
Enhanced MOR performance is linked to weakened binding of carbonaceous intermediates.
Exceptional long-term stability was observed, attributed to minimal cobalt dissolution.

Conclusions:

Pt-Co nanoframes represent a promising catalyst design for efficient and stable fuel cell applications.
The rational synthesis approach yields catalysts with superior activity for both ORR and MOR.
Understanding intermediate binding and metal dissolution is crucial for developing next-generation fuel cell catalysts.
