Covalent attachment of a rhenium bipyridyl CO2 reduction catalyst to Rutile TiO2.

چکیده
We have characterized the covalent binding of the CO(2) reduction electrocatalyst ReC0A (Re(CO)(3)Cl(dcbpy) (dcbpy =4,4'-dicarboxy-2,2'-bipyridine)) to the TiO(2) rutile (001) surface. The analysis based on sum frequency generation (SFG) spectroscopy and density functional theory (DFT) calculations indicates that ReC0A binds to TiO(2) through the carboxylate groups in bidentate or tridentate linkage motifs. The adsorbed complex has the dcbpy moiety nearly perpendicular to the TiO(2) surface and the Re exposed to the solution in a configuration suitable for catalysis.

Orientation of a Series of CO2 Reduction Catalysts on Single Crystal TiO2 Probed by Phase-Sensitive Vibrational Sum Frequency Generation Spectroscopy (PS-VSFG)
We report the average molecular orientation of a series of rhenium bipyridyl CO2 reduction catalysts adsorbed onto a rutile TiO2(001) single crystal surface. The molecular conformation of these catalysts on electrode surfaces is expected to affect their overall catalytic efficiency, since the catalytic Re center must be free to coordinate a CO2 molecule in working systems. Phase-sensitive vibra...
متن کاملSurface-Induced Anisotropic Binding of a Rhenium CO2‐Reduction Catalyst on Rutile TiO2(110) Surfaces
Vibrational sum frequency generation (SFG) spectroscopy has been utilized to study the spatial orientation and alignment of Re(CO)3Cl(dcbpy) (dcbpy = 4,4′-dicarboxy2,2′-bipyridine) (or ReC0A) on the (001) and (110) surfaces of rutile single-crystalline TiO2. The SFG intensity of the CO stretching modes shows an isotropic distribution on the (001) surface and an anisotropic distribution on the (...

This work investigates the photoinduced energy transfer from poly(N-vinylcarbazole) (PVK), as a donor material, to fac-(2,2'-bipyridyl)Re(CO)3Cl, as a catalyst acceptor, for its potential application towards CO2 reduction. Photoluminescence quenching experiments reveal dynamic quenching through resonance energy transfer in solid donor/acceptor mixtures and in solid/liquid systems. The bimolecul...
متن کاملInterfacial photoreduction of supercritical CO2 by an aqueous catalyst.
Carbon dioxide (CO2) emissions currently represent a major concern. Accordingly, the electrochemical reduction of CO2 is a reaction of major relevance and also of great challenges. Considering the redox potentials required for reducing CO2, multi-electron-transfer, multiproton reactions are the most viable pathways for driving CO2 reduction. [2] Nonetheless, catalysts must be employed to overco...
متن کاملNoncovalent immobilization of electrocatalysts on carbon electrodes for fuel production.
We show that molecular catalysts for fuel-forming reactions can be immobilized on graphitic carbon electrode surfaces via noncovalent interactions. A pyrene-appended bipyridine ligand (P) serves as the linker between each complex and the surface. Immobilization of a rhodium proton-reduction catalyst, [Cp*Rh(P)Cl]Cl (1), and a rhenium CO2-reduction catalyst, Re(P)(CO)3Cl (2), afford electrocatal...
