Synthesis, Structures, and Properties of Metal Formates
… (LRO). The second series of transition metal formates, [CH(NH2)2][M(HCOO)3] (M= Mn[3.1], Fe[3.2], Co[3.3], Ni[3.4], have 3D-framework structures. The compound [3.1] has phase transitions above and below room-temperature. Dielectric anomalies were observed in the vicinity of the phase …

Electrochemical studies in anhydrous formic acid
… of ammonium, alkali and alkaline earth formates as well as hydrogen chloride solutions in anhydrous formic acid were measured together with the behaviour of mixtures of two salts containing a common ion. More recently, Lange has measured the conductance of potassium chloride in this …

Spectroscopic Studies and Reaction Mechanisms of Small Molecule Oxidation over Metal Oxide-Supported Catalysts
… upon the production of stable surface-bound formates. Gaseous oxygen was found to subsequently oxidize these surface formates into the full oxidation product, CO2. Next, the oxidation of methanol was studied over the same Pt/TiO2 catalyst. It was discovered that the water produced when …

Mechanistic and spectroscopic methods for identifying reactive intermediate structures and active site properties over metals, metal oxides, and metal phosphides
… TiO2 convert through monodentate and bidentate formates to form CO and CO2 while residual bidentate formates bind strongly to the TiO2 surface. The addition of Au or co-fed water decreases the accumulation of residual bidentate formates, which suggests Au facilitates the diffusion of water …

Partial Oxidation of Hydrocarbons Over Ceria Zirconia Catalysts
… in the partial oxidation of methane to methanol; formates are formed in all cases, and these species are associated with the complete combustion of methane to carbon dioxide and water. Chemical looping may be an appropriate reaction engineering method to increase the yield of selective oxidation …

Increasing the temperature stability of environmentally friendly drilling and completion fluids based on organic brine.
Formates provide an already superior system, designed to complement synthetic polymers and extend their temperature capabilities as drilling fluids. However, as HPHT drilling continues to move into more harsh environments with expected bottom-hole temperatures of over 300°C; further research is …

Synthese und Charakterisierung von späten oxamat- und carboxylatstabilisierten 3d-Übergangsmetallkomplexen und deren materialwissenschaftliches Anwendungspotential
Die vorliegende Arbeit beschäftigt sich mit der Darstellung von paramagnetischen diskreten mono-, di- und multinuklearen sowie polymeren Koordinationsverbindungen. Der Schwerpunkt dieser Arbeit bildet neben der chemischen und strukturellen Charakterisierung die magnetische Charakterisierung mittels …
