Materials for carbon dioxide (CO2) gas detection are needed as emissions of this gas increase. In this research, hydroxyapatite (HA) was composited with lanthanum strontium cobalt ferrite (LSCF) to detect CO2 gas. HA was synthesized from chicken egg shells and the composite was synthesized using the hydrothermal method. The HALSCF composite was characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, and scanning electron microscopy. The synthesized HA has a rod-shaped morphology with an average size of 27 nm. The addition of LSCF to HA is known to influence its morphology, crystallinity, and electron density. The HA-LSCF 0.5 % composite has the highest crystallinity and electron density from the Fourier map data. Gas sensor measurements shows that at a temperature of 250 degrees C, HA-LSCF 0.5 % has a response value of 30, higher than pure HA. It is concluded that LSCF has a role in increasing the interaction of HA with carbon dioxide gas.
