چکیده

The reduction of the rhenium aryldiazenido complex [Cp*Re(CO)z(P-N2C&OMe)][BFJ results in the formation of the corresponding metal-bound dinitrogen complex Cp*Re(C0)2(N2). The mechanism of this transformation has been investigated by cyclic voltammetry (0, controlled-potentia1 electrolysis (CPE), and scanning electrochemical microscopy (SECM). The SECM analysis supported an electrochemical E& mechanism for the reduction of the cationic aryldiazenido complex to the neutral dinitrogen complex.

Bimetallic carbonyl thiolates as functional models for Fe-only hydrogenases.

The anion [Fe(2)(S(2)C(3)H(6))(CN)(CO)(4)(PMe(3))](-) (2(-)) is protonated by sulfuric or toluenesulfonic acid to give HFe(2)(S(2)C(3)H(6))(CN)(CO)(4)(PMe(3)) (2H), the structure of which has the hydride bridging the Fe atoms with the PMe(3) and CN(-) trans to the same sulfur atom. (1)H, (13)C, and (31)P NMR spectroscopy revealed that HFe(2)(S(2)C(3)H(6))(CN)(CO)(4)(PMe(3)) is stereochemically ...

Preparation of Gd2O3 nanoparticles from a new precursor and their catalytic activity for electrochemical reduction of CO2 to CO

The mononuclear Gd(III) complex, [Gd(L)3(H2O)5] (where L is alizarin yellow R (NaC13H8N3O5)), has been prepared in H2O under reflux condition. The Gd(III) complex has been characterized by elemental analysis and spectroscopic methods (UV–Vis and FT–IR). The Gd2O3 nanoparticles were prepared by the calcination of the Gd(III) complex in air at different temperatures up to 600 °C for 2 h. The calc...

Hydrogen peroxide production in the oxygen reduction reaction at different electrocatalysts as quantified by scanning electrochemical microscopy.

We present data for H2O2 production at eight different materials tested as electrocatalysts for the oxygen reduction reaction (ORR) in 0.5 M H2SO4 (Hg, Au, Ag, Cu, Pt, Pd, Pd80Co20, and Au60Cu40) using scanning electrochemical microscopy (SECM) as an alternative to the widely used rotating ring-disk electrode (RRDE) method. The amount of H2O2 is related to the total number of electrons, n, foun...
