Synthesis and structural characterization of CO-soluble oxidizers [BuN]BrO and [BuN]ClO and their dissolution in cosolvent-modified CO for reservoir applications.

CO utilization in upsteam oil and gas applications requires CO-soluble additives such as polymers, surfactants, and other components. Here we report the facile synthesis of CO-soluble oxidizers composed of judiciously selected organic cations paired with oxidizing anions. [BuN]BrO and [BuN]ClO are prepared using a double displacement synthetic strategy, whereby the crystalline product is readily obtained in high yield and structurally characterized using single-crystal X-ray diffraction.

In pursuit of advanced materials from single-source precursors based on metal carbonyls.

In this perspective, the development of single-source precursors and their relative advantages over multiple source approaches for the synthesis of metal pnictide solid state materials is explored. Particular efforts in the selective production of iron phosphide materials for catalytic applications are discussed, especially directed towards the hydrogen evolution and oxygen evolution reactions of water splitting.

A TiO/FeMnP Core/Shell Nanorod Array Photoanode for Efficient Photoelectrochemical Oxygen Evolution.

A variety of catalysts have recently been developed for electrocatalytic oxygen evolution, but very few of them can be readily integrated with semiconducting light absorbers for photoelectrochemical or photocatalytic water splitting. Here, we demonstrate an efficient core/shell photoanode with a highly active oxygen evolution electrocatalyst shell (FeMnP) and semiconductor core (rutile TiO) for photoelectrochemical oxygen evolution reaction. Metal-organic chemical vapor deposition from a single-source precursor was used to ensure good contact between the FeMnP and the TiO.

Synthesis of Hexagonal FeMnP Thin Films from a Single-Source Molecular Precursor.

The first heterobimetallic phosphide thin film containing iron, manganese, and phosphorus, derived from the single-source precursor FeMn(CO) (μ-PH ), has been prepared using a home-built metal-organic chemical vapor deposition apparatus. The thin film contains the same ratio of iron, manganese, and phosphorus as the initial precursor. The film becomes oxidized when deposited on a quartz substrate, whereas the film deposited on an alumina substrate provides a more homogeneous product.

Anionic Bismuth-Oxido Carboxylate Clusters with Transition Metal Countercations.

Six new anionic bismuth-oxido clusters containing trifluoroacetate ligands were prepared. These include two new BiO clusters: [M(NCMe)(HO)][Bi(μ-O)(μ-OH)(CFCO)] with an octahedral BiO(OH) core (M = Ni, 1a; Co, 1b) and four BiO clusters, {[Co(NCMe)][Bi(μ-O)(CFCO)]} (2a), {[Co{HC(MeCO)(MeCNH)}][Bi(μ-O)(CFCO)]·2[CFCO]·2[CFCOH]·2[HO]} (2b), {[Cu(NCMe)][Bi(μ-O)(CFCO)]·2[CFCOH]} (2c), and {[MeN][Bi(μ-O)(CFCO)]·2[CFCOH]} (2d). These are among the first bismuth-oxido anionic clusters synthesized, and the first to have transition metal countercations.

New Main-Group-Element-Rich nido-Octahedral Cluster System: Synthesis and Characterization of [Et4N][Fe2(CO)6(μ3-As){μ3-EFe(CO)4}2].

A series of clusters of the form [Et4N][Fe2(CO)6(μ3-As)}(μ3-EFe(CO)4)], where E is either P or As, were synthesized from [Et4N]2[HAs{Fe(CO)4}3] and ECl3. AsCl3 gives the As-only compound; PCl3 produces compounds having two As atoms with one P atom, or one As atom and two P atoms, and they can exist as two possible isomers, one of which is chiral. The As2P and AsP2 clusters cocrystallize, and their structure as determined by single-crystal X-ray diffraction is given along with the structure of the As-only cluster.

Asphalt-derived high surface area activated porous carbons for carbon dioxide capture.

Research activity toward the development of new sorbents for carbon dioxide (CO2) capture have been increasing quickly. Despite the variety of existing materials with high surface areas and high CO2 uptake performances, the cost of the materials remains a dominant factor in slowing their industrial applications. Here we report preparation and CO2 uptake performance of microporous carbon materials synthesized from asphalt, a very inexpensive carbon source.
