(2) To establish structure-function relationships

(3) To seek major breakthroughs from activity, stability, and cost

(4) To demonstrate the potential for large-scale applications

 

Capability:

(1) Nano-material synthesis with well-defined morphology

- Carrying out most of the preparation methods regarding liquid-phase chemical reaction

- Separation of nano-materials from liquid solvent via high-speed centrifuge (up to 16,000 rpm)

- Power drying via vacuum oven

- Calcination of as-synthesized material at various gas environment and high temperature (up to 1,200 °C)

(2) Half-cell tests to obtain the material activity and stability, and study the reaction mechanism

- Cyclic voltammetry (CV)

- Linear sweep voltammetry (LSV)

- Electrochemical impedance spectrum (EIS)

- Chronoamperometry

- Chronopotentiometry

- Corrosion Potential
