We describe the electrooxidation and size stability of 0.9 nm average diameter triphenylphosphine monosulfonate (TPPS)‐stabilized Au nanoclusters (NCs) as compared to 1.6 nm tetrakis(hydroxymethyl)phosphonium chloride (THPC)‐stabilized Au NCs and 4.1 nm citrate (Cit)‐stabilized Au nanoparticles (NPs). The potential for oxidative dissolution in KBr follows the order of TPPS Au 0.9nm NCs (0.219 V)
