Two times hydrolyzation of Fe~(3+) and Cr~(3+) was firstly pointed out in the process of pillar preparation with hydrothermal method. In order to improve the thermal stability, Fe/Cr-Si-pillaring agent solution was synthesized by hydrolyzing Fe~(3+) and Cr~(3+) solution on the surface of silica sol, and Fe/Cr-Si-pillared montmorillonite (Fe/Cr-Si-PILM) was prepared with conventional method and hydrothermal method.

The microstructure and morphology are examined by SEM, XRD, EPMA, and the electrochemical performance is studied by potentiodynamic polarization and current efficiency. The results show that the alloy elements in the electrode coating prepared by the sol-gel process are well distributed, more sufficient to form solid solution and with higher current efficiency than by the traditional thermal decomposition process. The deactivation effect is due to the forming of unconductive TiO2 for the sol-gel process, but due to the dissolution of active composition for the thermal decomposition process.
