“…1. The Ru 3d 5/2 was observed at 281.4 eV, which is close to the values 25,[49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64] for Ru 4ϩ in RuO 2 ͑280.7-281.3 eV͒. Hence, the K:Ru:O ratio should be K 0.2 RuO 2.1 and H 0.2 RuO 2.1 , assuming ion-exchange of K ϩ with H ϩ .…”

A hydrous ruthenic acid (H 0.2 RuO 2.1 •nH 2 O) possessing a layered structure with a crystalline framework was prepared by proton exchange of a layered potassium ruthenate. Its electrochemical capacitor behavior was studied by cyclic voltammetry in various electrolytes. Specific capacitance up to 390 F g ͑RuO 2 )Ϫ1 at a scan rate of 50 mV s Ϫ1 , which is a ten-fold increase compared to conventional anhydrous RuO 2 , was obtained using layered ruthenic acid hydrate in 0.5 M H 2 SO 4 electrolyte. Slightly lower values were obtained for 1 M HClO 4 and 1 M KOH electrolytes. The difference in the specific capacitance of anhydrous ruthenium oxide, hydrous ruthenium oxide, hydrous ruthenic acid, and restacked ruthenic acid nanosheets in the various electrolytes is discussed.

“…These composites prove advantageous because they combine electrocatalytic activity with the increased chemical and mechanical stability provided by the valve metal. 3 In this context different synthetic routes 4 have been directed towards the preparation of nanocrystalline materials whose high surface-tovolume ratio is generally expected to improve electrode performance.…”

Dedicated to Professor Otto BROMMER on the occasion of his 70th birthday Combined photoemission core level and satellite structure investigations of pyrolytic titanium-rich Ti,Ru, -,-oxide layers (0.90 5 x 5 0.97) and RuO, layers on titanium are used to gain structural and compositional information about these electro-catalytically active surfaces. By means of this method deviations from stoichiometry, the formation of carbon interstitials and the growth of anatase by ruthenium loss could be pointed out.
