Using Neutron Spin−Echo To Investigate Proton Dynamics in Proton-Conducting Perovskites
Source abstract
Abstract
The intermediate scattering function, I(Q,t), of proton-conducting hydrated BaZr0.90Y0.10O2.95 is explored for temperatures in the range 473−650 K and momentum transfers Q = 0.15−0.3 Å−1. The exponential decay of I(Q,t) suggests that the long-range self-diffusion of protons, which occurs as a series of proton transfers between neighboring oxygens and reorientational motion of the −OH group in between such transfers, is observed.
