Modulating the water oxidation catalytic activity of iridium complexes by functionalizing the Cp*-ancillary ligand: hints on the nature of the active species

“…When citing, please refer to the published version. ), 42 this can be verified by plotting the measured TOF at any time as a function of ∆E for all three consecutive runs (Figure 7).…”

Uniform colloids of ruthenium dioxide hydrate evolved by the surface-catalyzed reduction of ruthenium tetroxide

“…Rearrangement and integration of eq 9 give Ip = ((3 MkpC0p)/rJt (10) where Ip = J0V2/3(l-arp da (ID When growth commences from seed particles of significant size, the relevant expression for Ip is Ip(a) -( ), where s0 is defined as in eq 6.…”

“…23 Furthermore, it has been shown that dispersions of Ru02-xH20 act as microelectrodes when catalyzing the oxidation of water by cerium(IV) ions. 10 The Ru02-xH20/Ru04 and H20/02 couples are assumed to act as shown in eqs 15 and 16, respectively:…”

“…3 More recently, it has been demonstrated that dispersions of ruthenium dioxide hydrate (Ru02*xH20) are active catalysts for the oxidation of water by aqueous redox couples. [4][5][6][7][8][9][10] Matijevic,11 discussing the field of (hydrous) metal oxides generally, has pointed out that, in addition to their aesthetic appeal, monodisperse colloids exhibiting spherical particle symmetry facilitate the development of theoretical (mathematical) treatments of heterogeneous systems. To this end, Porta et al have recently described the preparation of uniform spherical particles of anhydrous ruthenium dioxide (Ru02) by heating silica-coated spheres of ruthenium (III/IV) ammine oxycarbonate in air at 400 °C.…”

“…One obvious attempt is the approximation with Butler-Volmer kinetics and the use of a very large heterogeneous rate constant [7,18,19]. The boundary conditions (e.g.…”
