摘要: The performance and durability of a noble metal coating anode for oxygen evolution was investigated in molten Li2CO3-Na2CO3-K2CO3 at 450 degrees C for the first time. The consuming rate of Pt was evaluated to be below 4.1 x 10(-2) mm/a under anodic polarization by weight-loss and melt analysis measurements. The metallic substrate, titanium can be anodically passivated by forming a dense Li2TiO3 film in the melt. Platinum coated titanium (Pt/Ti) anode exhibited excellent durability within 100h electrolysis, but slight oxygen penetration under the coating was observed, which might lead to the failure of the material for much longer term application.
