Patterning of BiVO4 Surfaces and Monitoring of Localized Catalytic Activity Using Scanning Photoelectrochemical Microscopy

There is a lot of interest in understanding localized catalytic activities at the micro and nanoscale and designing robust catalysts for photoelectrochemical oxidation of water to address the pressing energy and environmental challenges. Here, we demonstrate that scanning photoelectrochemical microscopy (SPECM) can be effectively employed as a novel technique (i) to modify a photocatalyst surface with an electrocatalyst layer in a matrix fashion and (ii) to monitor its localized activity toward the photoelectrochemical (PEC) water oxidation reaction. The three-dimensional SPECM image clearly shows that the loading of the FeOOH electrocatalyst on the BiVO4 semiconductor surface strongly affects its local PEC reaction activity. The optimal photoelectrodeposition time of FeOOH on the BiVO4 photocatalyst was found to be a?20 min when FeOOH was employed as the electrocatalyst. The electrocatalyst optimization process was conducted on a single photoanode electrode surface, making the optimization process efficient and reliable. The morphology of the formed photocatalyst/electrocatalyst hybrid, inclusive of its localized activity toward the water oxidation reaction, was simultaneously probed. A photoanode surface comprising CuWO4/BiVO4/FeOOH was further prepared in this study and investigated. It was found that the localized photoactivity truly reflects the activity of the local area, differs from region to region, and is contingent on the morphology of the surface. Moreover, the Pt UME is determined as an efficient probe to analyze the photoactivity of the PEC water splitting reaction. This work highlights the novel SPECM technique for enhancement and examination of the catalytic activity of the nanostructured materials.

Heterometallic platinum(ii) compounds with beta-aminoethylferrocenes: Synthesis, electrochemical behaviour and anticancer activity

A new family of heterometallic compounds 3-6 containing ferrocenyl and platinum(ii) centers has been synthesized by reaction of 1-beta- aminoethylferrocene (1) and 1,1?-bis(beta-aminoethyl)ferrocene (2) with Pt(ii) precursors. Using K2[PtCl4] as the Pt(ii) source, the cis-square-planar neutral compounds [Fe{eta5-C 5H4(CH2)2NH2} 2PtCl2] (3) and [{Fe(eta5-C5H 4(CH2)2NH2)(eta5-C 5H5)}2PtCl2] (5) were obtained. Reaction of cis-[PtCl2(dmso)2] with 1 and 2 resulted in the displacement of dmso and chloride ligands from the platinum coordination sphere, affording the cationic and neutral compounds [Fe{eta5- C5H4(CH2)2NH2} 2Pt(dmso)Cl]Cl (4) and [Fe(eta5-C5H 4(CH2)2NH2)(eta5-C 5H5)Pt(dmso)Cl2] (6). Compounds 3-6 were thoroughly characterized using multinuclear (1H, 13C, 195Pt) NMR, IR spectroscopy, ESI mass spectrometry and elemental analysis. Single-crystal X-ray analysis of heterometallic 6 confirmed the cis geometry of the molecule and revealed that the platinum atom is held in a perfect square-planar geometry. The electrochemical behaviour of the heterometallic compounds 3-6, which has been examined by cyclic (CV) and square wave (SWV) voltammetries in dichloromethane and dmso solution, is characterized by the reversible one-electron oxidation of the ferrocene moieties. The results of the biological activity studies revealed that the organometallic complex 5 is active against all cell lines with GI50 values in the range 1.7-2.3 muM. When compared to the standard anticancer drug cisplatin, heterotrimetallic 5, possessing two aminoethylferrocenyl units coordinated to the Pt(ii) center, showed a greater activity profile in the colon cancer cell line. Cell cycle studies revealed that the new mixed compound exhibits a mechanism of action different to cisplatin.

Cycloaddition of o-Carboryne with Vinyl Ethers: Synthesis of Carborane-Fused Cyclobutanes

o-Carboryne (1,2-dehydro-o-carborane) is a very useful synthon for the synthesis of a variety of carborane-functionalized molecules. Using 1-Li-2-OTf-o-C2B10H10 as a precursor, o-carboryne undergoes an efficient [2 + 2] cycloaddition with a large variety of vinyl ethers at room temperature to give a series of carborane-fused cyclobutanes in very good to high isolated yields. This reaction is compatible with many functional groups and has a very broad substrate scope ranging from alkyl- to aryl- and to silyl-substituted vinyl ethers. A stepwise reaction mechanism is proposed based on the control experiments, which is supported by DFT calculations. All new compounds have been fully characterized by 1H, 13C, and 11B NMR spectroscopy as well as HRMS spectrometry. Some are further confirmed by single-crystal X-ray analyses.

Mediated Fuel Cells: Soluble Redox Mediators and Their Applications to Electrochemical Reduction of O2 and Oxidation of H2, Alcohols, Biomass, and Complex Fuels

Mediated fuel cells are electrochemical devices that produce power in a manner similar to that of conventional proton exchange membrane fuel cells (PEMFCs). They differ from PEMFCs in their use of redox mediators dissolved in liquid electrolyte to conduct oxidation of the fuel or reduction of the oxidant, typically O2, in bulk solution. The mediators transport electrons (and often protons) between the electrode and the catalysts or chemical reagents in solution. This strategy can help overcome many of the challenges associated with conventional fuel cells, including managing complex multiphase reactions (as in O2 reduction) or the use of challenging or heterogeneous fuels, such as hydrocarbons, polyols, and biomass. Mediators are also commonly used in enzymatic fuel cells, where direct electron transfer from the electrode to the enzymatic active site can be slow. This review provides a comprehensive survey of historical and recent mediated fuel cell efforts, including applications using chemical and enzymatic catalysts.

Electronic structure and near-IR transitions of FcC2R and FcC4R dyads

This paper describes the orbital configuration which provides a basis for the understanding of the electronic structure and spectroscopic properties of 17e and 18e FcC2R and FcC4R dyads, where R is H, 1-naphthyl, 9-anthryl, 3-pyrenyl, perylenyl. DFT calculations show that destabilisation of the ferrocenyl pi orbitals upon binding a C{triple bond, long}CR group to a Cp ring leads to the metal-based a1 orbital dropping below the e1-a so that the frontier orbital configuration is (e2? -a, pi)2 (e2? -b,metal)2 (e1? -a, pi)2, (a1, metal)2. The contribution of the aryl group to the pi e2-a and e1-a orbitals varies with the annelation of the ring. The LUMO is aryl based. The calculations are consistent with the spectroscopic data for the 18e species. Oxidation to the 17e cations does not change the orbital configuration but the orbital energies are lowered by the positive charge centred on the Fe. A strongly solvatochromic transition in the near-IR, a signature for the 17e cations, is best described as an LMCT transition but the contribution of C2R and C4R to the donor and acceptor levels depends on the ionization energy of the aryl pi orbital. LMCT energies decrease from FcC2R to FcC4R dyads.
