Chemical looping combustion (CLC) represents an innovative cyclic approach to fuel combustion aimed at inherently separating carbon dioxide. In this process, oxygen moves between air and fuel reactors using metal oxide particles known as oxygen carriers (OCs). During the reduction step, the OCs are introduced into the fuel reactor to combust the fuel. In the oxidation step, the reduced OCs are conveyed to the air reactor to gain oxygen from the airflow. This study focuses on synthesizing a yolk-shell structure using alumina (Al2O3) as the yolk and zirconia (ZrO2) as the shell to support the OC, with copper oxide impregnated onto its surface. The structural and cyclic reduction-oxidation (redox) performance of the CuO-impregnated yolk-shell sample is compared with that of CuO-impregnated core-shell samples and CuO-impregnated alumina oxygen carriers in CLC at the temperature of 800 ⁰C. The yolk-shell material successfully achieves homogeneous zirconia coating on alumina, leading to a narrower pore size distribution. Additionally, the yolk-shell structure prevents direct contact between the alumina yolk and copper oxide, inhibiting the formation of CuAl2O4 spinel. The synthesized oxygen carriers undergo characterization using techniques such as Brunauer-Emmet-Teller (BET) analysis, X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDX) dot mapping. Results indicate that the oxygen carrier supported by the yolk-shell demonstrates superior activity, oxygen transport capacity, and resistance to coke formation.
