摘要：

This paper demonstrates that nano-powder of a layered protonated titanate (H2Ti2O5 center dot H2O; LPT) compound exhibits a significant proton conductivity. The conductivity was measured on the compact of the un-milled/milled powder and it reached higher than 10(-2) S cm(-1) at 95 degrees C in water in the milled case. The increase in conductivity of LPT after bead milling along with the thermogravimetric and surface area analysis suggested that the protonic conduction takes place on the surface of the nanoparticles in contact with water.
