Device System


To convert carbon dioxide into high-value compounds using electrical energy, device-ization technology is needed to apply the catalyst to actual devices.
Our lab has applied the electrode materials we developed to large-area stack reactors, expanding research beyond laboratory scale to pilot-level systems.

Electrochemical 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.

Stack System for CO₂

Reduction Reaction (CO₂RR)


Electrochemical reduction of carbon dioxide represents a possible means

of producing chemicals or fuels, converting carbon dioxide(CO₂) to organic

feedstocks such as formic acid(HCOOH), methanol (CH3OH),

ethylene(C₂H4), methane(CH4), and carbon monoxide(CO). In our lab,

electrode and cell design was researched to produce large amount of

valuable chemicals.

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.

Electrochemical Flow Cell for

in-situ/Operando Analysis


In-situ/Operando analysis is an analytical methodology wherein the

spectroscopic characterization of materials undergoing reaction is coupled simultaneously with measurement of catalytic activity and selectivity.

The primary concern of this methodology is to establish

structure-reactivity/selectivity relationships of catalysts and thereby yield

information about mechanisms. Other uses include those in engineering

improvements to existing catalytic materials and processes and in

developing new ones. In situ/operando analysis requires measurement of

the catalyst under (ideally) real working conditions, involving comparable

temperature and pressure environments to those of industrially catalyzed

reactions. In our lab, various In situ/operando analysis was prepared for

mechanism and characterize study using techniques such as XRD, ICP,

XAFS, and Raman.
