Graphene Oxide Functionalized with Cationic Porphyrins as Materials for the Photodegradation of Rhodamine B
TLDR
The data indicate that the presence of Zn(II) in the core of the porphyrin can promote charge separation in the ZnTMPyP–GO composites.

How Eosin Y/Graphene Oxide-Based Materials Can Improve Efficiency of Light-Driven Hydrogen Generation: Mechanistic Aspects
We have demonstrated that the photocatalytic system, containing Eosin Y (EY) as a sensitizer, triethanolamine (TEOA) as a sacrificial electron donor, CoSO4 as a catalyst, and graphene oxide (GO), e...

Mechanism of the quenching of the tris(bipyridine)ruthenium(II) emission by persulfate: implications for photoinduced oxidation reactions.
TLDR
The proposed model accurately describes experimental results for the quenching of *Ru(bpy)3(2+) over a wide range of persulfate concentrations and resolves some discrepancies between the values of K(IP) and k(et) previously reported.

Water Oxidation by Ruthenium Complexes Incorporating Multifunctional Bipyridyl Diphosphonate Ligands.
TLDR
The synthesis and characterization of ruthenium complexes with multifunctional bipyridyl diphosphonate ligands as well as initial water oxidation studies are described, which are among the fastest single-site catalysts reported to date.

Efficient water oxidation with organometallic iridium complexes as precatalysts.
TLDR
Analysis of spectroscopic data together with O2-evolution experiments using Cp*Ir(6,6′-dihydroxy-2,2′-bipyridine)(OH2)(2+) as a precatalyst indicate that the high catalytic activity is closely connected with transient species (A) that exhibits an absorption band at λmax 590 nm.

Mechanistic studies of hydrogen evolution in aqueous solution catalyzed by a tertpyridine-amine cobalt complex.
TLDR
This work investigates the properties of intermediates produced during catalytic proton reduction in aqueous solutions promoted by the [(DPA-Bpy)Co(OH2)](n+) complex and proposes that this RDS may originate from the slow removal of a solvent ligand in the intermediate [Co(I)(κ(4)-L)(OH2]-(+) in addition to the significant structural reorganization of the metal complex and surrounding solvent resulting in a high free energy of activation.

Enabling light-driven water oxidation via a low-energy RuIV=O intermediate.
TLDR
It is successfully demonstrated that this unique proton-coupled low-energy pathway actually takes place with the use of a mild oxidant such as the photogenerated [Ru(bpy)3](3+) (1.26 V vs. NHE) to drive water oxidation.

Striking Differences in Properties of Geometric Isomers of [Ir(tpy)(ppy)H](+): Experimental and Computational Studies of their Hydricities, Interaction with CO2, and Photochemistry.
TLDR
Two geometric isomers of [Ir(tpy)(ppy)H](+), previously proposed as a key intermediate in the photochemical reduction of CO2 to CO, are prepared and their notably different ground- and excited-state interactions with CO2 are characterized using experimental and computational methods.

Interaction of light with a non-covalent zinc porphyrin-graphene oxide nanohybrid.
The present study explores the influence of graphene oxide (GO) on deactivation pathways of the excited states of zinc 5,10,15,20-tetrakis(4-(hydroxyphenyl))porphyrin (ZnTPPH). The interaction of…

Lerf–Klinowski-type models of graphene oxide and reduced graphene oxide are robust in analyzing non-covalent functionalization with porphyrins
TLDR
This work validated finite, Lerf–Klinowski-type structural models of GO and RGO and successfully used them in ab initio absorption spectra simulations to track back the origin of experimentally observed spectral features.
