Observations of strong resistivity reduction in a palladium thin long wire using ultra-high frequency pulsed electrolysis at D/Pd>1

摘要

They performed ultra-short width high voltage pulse electrolysis using a thin Pd wire cathode; a diluted electrolytic solution of D2O+LiOD was used in a peculiar wire-turned electrodes geometry. The deuterated Pd loading was evaluated by the D/Pd normalised electric resistance curve (R/Ro). After a long time of electrolysis a very high D/Pd loading (1 : 1 or more) was reached. Very low R/Ro (< 0.1) Pd wire was measured after switching off the electrolysis and this effect lasted for several minutes. The Deuterium deloading occurred in several typologies (fast and slow terms) showed as a resistance transition on the Pd wire. This effect can be related to a peculiar surface structural condition.
