Chemical looping

Chemical looping is an innovative approach for converting fuel into valuable products such as hydrogen and syngas, inherently capturing CO₂. In this process, metal oxides, called oxygen carriers, role as both a catalyst and an oxygen source in the cyclic redox reactions. The performance of chemical looping systems strongly depends on the properties of the oxygen carriers, which play a key role in oxygen transfer and reaction efficiency. Our research focuses on the design of an advanced oxygen carrier for sustainable chemical production.

Below are research topics from our laboratory focusing on oxygen carrier (catalyst) for chemical looping

Catalyst design

We design advanced oxygen carriers using various synthetic strategies (such as impregnation, Pechini, sol-gel, doping, exsolution, template-assisted-structuring, and core-shell) that improve physicochemical properties to enhance performance (such as reaction kinetics, thermodynamic favorability, thermal stability) in the chemical looping process.

Catalyst evaluation

We evaluate catalysts through both experimental (such as physicochemical analysis, temperature-programmed experiments, cyclic experiments) and theoretical methods (such as Aspen Plus simulation, DFT calculation). These integrated methods enable a comprehensive understanding of the catalyst and provide fundamental insights into the reaction mechanism.
