The Adsorption of Ru-Based Dyes on the TiO₂ Surface to Enhance the Photovoltaic Efficiency of Dye-Sensitized Solar Cell Devices

Molecules
Adsorption of mononuclear tris(bipyridine) ruthenium(II) complexes and binuclear tris(bipyridine) ruthenium(II) complexes equipped with carboxyl groups (-COOH) on the (111) surface of TiO2 crystal in anatase form was modeled using Monte Carlo simulations,

Preparation of Ruthenium Dithiolene Complex/Polysiloxane Films and Their Responses to CO Gas

Molecules, 2018
To develop advanced materials using metal complexes, it is better to prepare metal complexes contained in composite or hybrid films. To achieve this purpose, we synthesized ruthenium complexes with dihalogen-substituted benzendithiolate ligands, [(η6 ...

Toward Fast Proton Shuttling in Acidic Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
This review establishes proton transfer dynamics as a descriptor governing acidic OER activity, moving beyond the kinetic constraints derived from the proton coupled electron transfer. We discuss how deprotonation governs classical mechanisms, including adsorbate evolution mechanism (AEM), lattice oxygen mechanism (LOM) and oxide path mechanism (OPM ...

Ammine Complexes of Ruthenium

Platinum Metals Review, 1969
Ammines not previously described, and simple routes to others which have earlier been difficult to prepare, have been discovered as a result of the isolation of the bivalent ruthenium ammine hexammineruthenium(II) chloride and a study of its reactions. Certain of these compounds could have commercial significance, for example in electrodeposition or in

SYNTHESIS AND CHARACTERIZATION OF FULLERENE-PYRIDYL ARENE RUTHENIUM COMPLEXES

Studia Universitatis Babes-Bolyai Chemia, 2015
Association of [60]fullerene with arene ruthenium moieties has been achieved for the first time. Two fullerenopyrrolidine derivatives (Npyr-C60) were synthesized via a 1,3-dipolar cycloaddition, and coordinated to arene ruthenium complexes to form two ...

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

Advanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...
