We further demonstrate that the chloride concentration in solution heavily influences the characteristic current spike shape of recorded nanoparticle impacts: While typically too short to be resolved in the measured current, the spike widths are significantly broadened at low chloride concentrations below 10 mm and range into the millisecond regime. The analysis of more than 25 000 spikes reveals that this effect can be explained by the diffusive mass transport of chloride ions to the nanoparticle, which limits the oxidation rate of individual silver nanoparticles to silver chloride at the chosen electrode potential. 000837518 536__ $$0G:(DE-HGF)POF3-523$$a523 - Controlling Configuration-Based Phenomena (POF3-523)$$cPOF3-523$$fPOF III$$x0 000837518 588__ $$aDataset connected to CrossRef 000837518 7001_ $$0P:(DE-Juel1)161443$$aBrings, Fabian$$b1 000837518 7001_ $$0P:(DE-Juel1)140152$$aSchnitker, Jan$$b2 000837518 7001_ $$0P:(DE-Juel1)128700$$aKätelhön, Enno$$b3 000837518 7001_ $$0P:(DE-Juel1)140264$$aRinklin, Philipp$$b4 000837518 7001_ $$0P:(DE-Juel1)128707$$aMayer, Dirk$$b5 000837518 7001_ $$0P:(DE-HGF)0$$aCompton, Richard G.$$b6 000837518 7001_ $$0P:(DE-HGF)0$$aLemay, Serge G.$$b7 000837518 7001_ $$0P:(DE-Juel1)128713$$aOffenhäusser, Andreas$$b8 000837518 7001_ $$0P:(DE-Juel1)128745$$aWolfrum, Bernhard$$b9$$eCorresponding author 000837518 773__ $$0PERI:(DE-600)1478547-x$$a10.1002/chem.201605924$$gVol. 23, no. 19, p. 4638 - 4643$$n19$$p4638 - 4643$$tChemistry - a European journal$$v23$$x0947-6539$$y2017 000837518 8564_ $$uhttps://juser.fz-juelich.de/record/837518/files/chem.201605924.pdf$$yPublished on 2017-11-23.
