Electrochemical Devices

  Research about Devices 

An electrochemical device is a cell capable of either generating electrical energy

from chemical reactions or using electrical energy to cause chemical reactions.

The electrochemical device which generate an electric current are called voltaic

cells or galvanic cells and those that generate chemical reactions,

via electrolysis for example, are called electrolytic cells.

Electrolyzer for Water Splitting

Electrolysis of water is the decomposition of water into oxygen and hydrogen gas

due to the passage of an electric current. The reaction has a standard potential of −1.23 V,

meaning it ideally requires a potential difference of 1.23 volts to split water.

In our lab, electrode and cell design was investigated

for high performance water splitting.

Non-noble Metal based Electrocatalysts for OER

Both computational and experimental studies have recently shown that the noble metal-based oxides such as Ir and Ru are most active electrocatalysts for OER. However, high cost and scarcity of these noble metal-based materials hinder their large-scale application. To overcome this problem, Our lab focused to develop non-noble metal-based electrode for OER. Our simple and scalable method appear to be promising method to ensure economic feasibility.

Non-noble Metal based Electrocatalysts for CO2RR

The electrochemical reduction of CO2 using renewable electricity is an important future CO2-to fuels/chemicals process, which converts the greenhouse gas CO2 directly into useful chemicals, polymer precursors, and fuels, such as carbon monoxide (CO), acetaldehyde, ethylene, and ethanol. However, the CO2RR faces formidable obstacles with respect to commercialization due to its low efficiency and poor selectivity. Our research has been dedicated to identifying efficient and selective catalysts for CO2RR. Our studies highlight the need for a concomitant consideration of factors related to intrinsic catalytic activity of the active phase, its porous structure and its hydrophilicity/phobicity

to achieve a sustained high product yield

Photo Electrochemical Devices

Solar to fuel is a synthetic chemical fuel produced directly/indirectly

from solar energy sunlight/solar heat through photochemical/photobiological,

thermochemical (i.e., through the use of solar heat supplied by concentrated solar

thermal energy to drive a chemical reaction), and electrochemical reaction.

Light is used as an energy source, with solar energy being transduced to chemical energy,

typically by reducing protons to hydrogen, or carbon dioxide to organic compounds.

In our lab, electrode and cell design was investigated for increasing solar to fuel efficiency.
