I joined UvA in 2014 after more than four years of research on solid oxide fuel cells at the University of Alberta in Canada. As a tenure-track assistant professor at the Van ’t Hoff Institute for Molecular Sciences, I am working in the Sustainable Chemistry Research Priority Area program and focusing on the (electro)catalyst design and development for clean energy applications, including fuel cells, supercapacitors, CO2 valorizations. In particular, developing high-performance yet robust metallic nanomaterials, perovskite oxide and porous carbons are my main interests. Recently, I was awarded the NWO-GDST Chemistry for Advanced Materials Grant (290 €k) to design cost-effective catalyst for the electroless plating of Cu in the printed circuit board.
(1) N-doped carbons and composites
Electrochemical oxygen reduction and evolution reactions (ORR and OER) are central to the field of energy conversion and storage. The problem is that both processes are sluggish, requiring precious-metal catalysts. Using nitrilotriacetates as the precursor and different synthesis procedures, we developed N-doped carbons and composites as the alternative catalysts. One article was featured in the 2017 Emerging Investigator issue of Green Chem.
(2) Double perovskite oxide
Double perovskite catalyst with a general formula of A2B2O5+δ demonstrated much higher oxygen ion diffusion rate and surface-exchange coefﬁcient relative to the ABO3-type perovskite. We developed a series of double perovskite oxide as the multi-functional electrocatalysts.
(3) Solid oxide fuel cells reactor
In addition, we have various materials characterization equipment in-house, including XRD, SEM, NMR, GC-MS, FTIR, UV-Vis, temperature-programmed techniques (TPDRO), gas/liquid adsorption equipment, mercury intrusion porosimetry and TGA-DSC.
Other critical analyses such as advanced TEM, XPS and Ramam are also available at our collaborating institutions.
