摘要:Method for producing glyoxylic acid by electroreduction, with cathodic reactivation, of oxalic acid in a divided eletrolytic cell comprised of an anodic compartment formed of an anode and an aqueous solution of a strong mineral acid as anolite and of a cathodic compartment formed of a lead cathod and an aqueous solution saturated with oxalic acid, the two compartments being separated by a cationic exchange membrane. The method comprises the addition of Pb(II) salts to the catholite or to the anolite in order to keep at high and constant levels throughout the operation both the current efficiency and the selectivity of the process. The effect of Pb (II) salts may be potentiated by washing the cathode with nitric acid. The glyoxylic acid is an intermediary in the industrial synthesis of p-hydroxyphenylglycine and vanillin, inter alia.

摘要:The subject invention pertains to the synthesis and characterization of V2O5/CdE NW/QD heterostructures. The V2O5/CdE heterostructures are versatile new materials constructs for light harvesting, charge separation, and the photocatalytic production of solar fuels; polymorphism of V2O5 and compositional alloying of both components provides for a substantial design space for tuning of interfacial energy offsets. Also provided are a new class of type-II heterostructures composed of cadmium chalcogenide QDs (CdE where E=S, Se, or Te) and α-V2O5 nanowires (NWs). The synthesis and characterization of V2O5/CdE NW/QD heterostructures, prepared via successive ionic layer adsorption and reaction (SILAR) and linker-assisted assembly (LAA), the characterization of their photoinduced charge-transfer reactivity using transient absorption spectroscopy, and their performance in the photocatalytic reduction of protons to hydrogen are also disclosed.
