| Summary: | The development and characteristic ofLa(l_x)FexMn oxide in storing hydrogen gas examined in this study. The adsorption capacity of La based alloy was monitored under the influence of mole fraction(x) which is x = 0.05, 0.1 and 0.2. Due to the limitation on its operating conditions, the pressure chosen was 2 bar while the temperature was 100°C in 1 hour experimental time. The alloy was process using sintering process pada suhu 550°C. Scanning electron microscopy (SEM) showed the microstructure of the La based alloy after the sintering process with the different of mole fraction in each samples. The thermal stability of the alloy was examined using thermal gravimetric analysis (TGA) apparatus. The Fourier Transform Infra Red (FTIR) was used to detect whether the hydrogenation process was occur in the alloy. The results of this study showed that adsorption process occur as well as oxidation process during the hydrogenation process. The smallest mole fraction(x) which is x = 0.05 showed the highest weight loss during the hydrogenation process. The adsorption of hydrogen in the alloy oxide was proved by FTlR using the detection of the wavelength in the range of 760 cm -I based on the previous research done by Fujimori et al. |
