CONSTRUCTION OF ROAD MAP FOR
ADVANCED FUNCTIONAL MATERIALS FOR
REMOVAL OF HAZARDOUS POLLUTANTS
IN AIR AND COMPARISON OF FIGURE OF
MERIT (FOM)

To effectively remove gaseous pollutants from air using sorbents, a
thorough knowledge of the actual sorption performance is needed at
ambient conditions rather than unrealistically high-pressure conditions, as
is commonly presented in the literature. To this end, the sorbent capacities
of gaseous pollutants including benzene, formaldehyde, ammonia, hydrogen
sulfide, etc. were evaluated at a constant sorbent bed inlet pressure (e.g.,
50 ppm or ~5 Pa), room temperature (298 K), a fixed flow rate (50 mL min-
1), and equal outlet sampling intervals (5 min). The adsorption patterns of
various pollutants were investigated against diverse materials including
advanced functional materials like metal organic frameworks, graphene
materials, and conventional sorbents like activated carbons for references.
The experimental results obtained for various pollutants by the tested sorbent
materials were further assessed by the Langmuir, Henry’s law, Freundlich,
Dubinin-Radushkevich and Elovich isothermmodels. The linearized Langmuir
adsorption isotherms were evaluated in various respects to help develop
a road map for pollutant removal by diverse materials. Further, the best
figure-of-merit data for each material was then assessed based on a high
10% breakthrough volume (BTV) and the actual cost involved for real-world
applications.
Ki-Hyun Kim was at Florida State University for an MS
(1984-1986) and at University of South Florida for a
PhD (1988-1992). He was a Research Associate at
ORNL, USA (1992 to 1994). In 1999, he joined Sejong
University. In 2014, he moved to the Department of
Civil and Environmental Engineering at Hanyang Uni-
versity. His research areas broadly cover the various
aspects in the field of air quality and material engi-
neering in connection with advanced novel materials
like coordination polymers. He was awarded as one of
the top 10 National Star Faculties in Korea in 2006. He
is a serving Editorial Board Member of several journals
(e.g., Environmental Research, Atmospheric Pollution
Research, and Sensors). He has published more than
530 articles, many of which are in leading scientific
journals like Chemical Society Reviews, Progress in
Material Science, Progress in Polymer Science, Coor-
dination Chemistry Reviews and Trends in Analytical
Chemistry.
