The temperature coefficient of the potential of zero charge of Ag single crystal electrodes, dE σ=0 /dT , was measured by recording capacitance curves at different temperatures. Two experimental approaches were adopted: the "continuity" and the "discontinuity" method, consisting in recording curves at different temperatures without and with extraction of the electrode from the solution, respectively. Appreciable differences have been observed. The origin of the differences and their significance are discussed in terms of keeping the appropriate conditions for the electrode/solution interface during the experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
