Case Study

Sc2O3 and CeO2 Co-Doped ZrO2 Electrolyte for Solid Oxide Fuel Cells

Lee, D-S., et al. Solid State Ionics, 2005, 176(1-2), 33-39.

Sc2O3 and CeO2 co-doped ZrO2 to achieve the development of better solid electrolyte materials for medium and low temperature solid oxide fuel cells (SOFCs). The results showed that the obtained ZrO2 doped with Sc2O3 and CeO2 showed higher conductivity and better long-term stability over the entire temperature range of 300-1100 °C.
Preparation procedures of ZrO2 co-doped with Sc2O3 and CeO2
· ZrO2 samples doped with Sc2O3 and CeO2 were prepared using standard ceramic processing methods. The initial powder consisted of ZrO2 doped with 10% Sc2O3 and 1% CeO2. This powder was pressed into pellets with a diameter of 10 mm and a thickness of 2 mm using a uniaxial press at 100 MPa, and then sintered in air for 1 hour within a temperature range of 1250-1550 °C. Samples were prepared at six different sintering temperatures to determine the optimal condition.
· To create the unit cell, a mixture of NiO/Sc-ZrO2 granules was compacted and pressed into plates measuring 8×8 cm2 in area and 2 mm in thickness. A thin film of Sc-ZrO2 (doped with 10% Sc2O3 and 1% CeO2) was then applied to the green anode substrate using screen printing, followed by co-firing at 1400 °C for 3 hours in air. A cathode composite of LSM/ScZrO2 was screen printed onto the sintered SZ surface and then sintered at 1200 °C for 3 hours in air. The final unit cell had dimensions of 5×5 cm2 in area and 1 mm in thickness.

Preparation and Application of Scandium Trioxide-Magneli Phase Titanium Composite Electrode

Bai, Hongmei, et al. Applied Surface Science, 2017, 401, 218-224.

The scandium trioxide-Magneli phase titanium (Sc2O3-MPT) composite electrode can be successfully prepared by pressing-sintering method. The prepared Sc2O3-MPT composite electrode can be used for electrocatalytic degradation of methyl orange (MO), and its degradation efficiency is as high as 90.16% under optimized conditions.
Preparation procedures of Sc2O3-MPT composite electrode
· To create the MPT electrode, a mechanically polished Ti plate was placed in a 10 wt% NaOH solution at 90 ℃ for 1 hour, then etched in boiling 10 wt% oxalic acid at 90 ℃ for 2 hours to ensure uniform surface roughness. TiO2 pellets were then formed by applying 50 MPa of uniaxial pressure and 250 MPa of isostatic pressure on the Ti plate. The pellets were sintered at 1300 ℃ for 5 hours in air, followed by reduction in a 93% Ar + 7% H2 atmosphere at 1000 ℃ for 4 hours.
· In the production of the Sc2O3-MPT composite electrode, 150 mg of TiO2 was dispersed in 100 mL of deionized water and ultrasonically stirred at room temperature for 1 hour to create a uniform aqueous suspension. Next, 4.5 mL of scandium isopropoxide in a hydroalcoholic medium was added to the suspension, which was then mechanically stirred overnight. The solvent was evaporated in a rotating evaporator at 60 ℃ and the resulting sample was dried at 80 ℃ in a vacuum overnight to eliminate any remaining water residue. Finally, the Sc2O3-MPT composite electrode was fabricated using a process similar to that of the MPT electrode.
