   Introduction  of  A113 Laboratory

 

 

 

 

 

Our research group working on energy and advanced technology applications through the investigation of solid oxide fuel cells, Photocatalysis for Wastewater treatment, Hydrogen Evolution through water splitting.

 

 

 

 

 

 

Solid Oxide Fuel Cells (SOFCs)

Our research focuses on how materials function in solid oxide fuel cells (SOFCs)—their durability, damage tolerance, and performance over time. By designing the component parts and understanding how they interact with each other.

SOFCs are similar to batteries, except they are constantly replenished with fuel and never run down. They are highly efficient, they don’t create noise pollution or release toxins into the environment, they can directly utilize a wide variety of commonly-available fuels, including natural gas, biogas, ethanol, methanol, hydrogen, carbon monoxide, and synthesis gas produced from coal or natural gas, without the thorough and extensive purification required for low-temperature fuel cells. 

SOFCs offer the benefits of sustainable electric power without the drawbacks of other alternative energy generators. They are a convenient, portable source of clean energy, unlike solar panels or wind farms, which depend on fickle natural elements and massive infrastructure. SOFCs are inexpensive to produce and require no new infrastructure investments.

Our main goal of research to find a good layered perovskite materials working in the intermediate temperature and the extensive studies Oxygen permeation, Thermal, Mechanical and Electrochemical properties.


 

 

 

 

 

 

 

Photocatalysis

Photocatalysis for Hydrogen production and water pollutant treatment are important research area for addressing global energy needs and environmental issues. Treatment of wastewater containing persistent organic and inorganic pollutants, prior to disposal into the environment, has attracted substantial interest over the past decades. The project will focus on fabrication of low cost, non toxic and highly efficient photocatalysts and their application in wastewater treatment. The relevant reaction mechanism will also be investigated by spectroscopies and other advanced technologies, which will be fed back to the material synthesis to improve the catalytic efficiency.








 

 

 

 

 

 

 

3. Tthe Material of Resource Recycle  

Utilizing recoverable material again that refined out from the pollution by scientific method, it is one of the developing directions in this laboratory. 

The pollution sources may come from:  

1.                  chemical industry

2.                 The waste of pernicious and noxious

      They have many kind of project of this laboratory developing. In general, the traditional methods of heavy metal waste water treatment including

(1) Ion exchange

      The micro-pollutant removed after the tradition law processing in the waste water. Accord the stricter environmental protection regulation, cleaning and recycling the waste water that is the electroplate solution include trace ions. That makes the purified water reflow and used usefully again. 

(2) Evaporation 

The method is recycling the chemical medicines form electroplates washing water. That removes large of water by heat to boil. The recycling medicines are concentrated then reuse in the electroplate bath. 

(3) Electrolysis 

Metal recycles by deposition from dilute solution, and the law especially applies to the noble metal. 

(4) Neutralization Precipitate 

 For the waste water of much metal ions, those also add the base solution to make it produce the hydroxide precipitating, which called Neutralization Precipitate. Sometime addition Fe2(SO4)3, Al(SO4)3 or macromolecule agglutinate, make the heavy metal ions precipitate at lower pH by congeal precipitation. The method can let waste water to flowing standard, but the method will produce much heavy metal mud that dehydrates difficultly. If abandon the dehydrate mud arbitrarily, that will dissolve out the heavy metal ions to make second environmental pollution by rain and groundwater. So must give some solidify device to the mud, because the mud is an unstable hydroxide, and the stable mud that can do oxidation and reduction. That also make the solidify body to crumble and split easily, that will pollute the environment again. 

Our focuses on improve the various method of pollutant treatment, that can reduce and improve the disadvantage of traditional treatment method, and develop the new technology of resource treatment actively. We expect the research results that can have some contribution for environmental protect in the future.
