Professor Sejin Kwon's research lab specializes in advanced propulsion systems and catalytic energy conversion, with a focus on green and high-performance space propulsion technologies. The lab develops innovative hybrid thrusters using environmentally friendly propellants such as nitrous oxide and hydrogen peroxide, integrating dual-catalyst systems to enhance efficiency and reduce preheating times. Research also extends to polymer-based fuels and catalytic decomposition processes, aiming to improve system durability and energy density for aerospace applications. The lab emphasizes sustainable propulsion solutions through catalytic materials engineering and system-level optimization.

This paper presents the design, fabrication and evaluation of a micro methanol reformer complete with a heat source. The micro system consists of the steam reforming reactor of methanol, the catalytic decomposition reactor of hydrogen peroxide, and a heat exchanger between the two reactors. In the present study, catalytic decomposition of hydrogen peroxide is used as a process to supply heat to the reforming reactor. The decomposition process of hydrogen peroxide produces water vapor and oxygen
