Abstract: A method of making an electrocatalyst, including dissolving a copper salt and an aromatic compound in a solvent to form a first mixture, heating the first mixture to a temperature of 90-120° C. for 1-20 hours (h) to form a copper complex, heating the copper complex under a nitrogen atmosphere at a temperature of 500-1,000° C. to form a nanocomposite; and coating a layer of the nanocomposite on a substrate to form the electrocatalyst. The nanocomposite contains copper nanoparticles (NPs) and nitrogen-doped carbon nanosheets. The copper NPs are uniformly dispersed on a surface of the nitrogen-doped carbon nanosheets, the nitrogen-doped carbon nanosheets have an average thickness of 0.1-10 nm, and the copper NPs are spherical and have an average diameter of 2-10 nm.

Abstract: A method of forming an electrode including dissolving a copper salt and benzene-1,3,5-tricarboxylate in a solvent and heating to a temperature of 60° C. to 100° C. to form a framework. Further, the method includes mixing a zinc salt and the framework to form a zinc doped framework and heating the zinc doped framework to a temperature of 300° C. to 600° C. under air to form ZnCuO nanoparticles. Furthermore, the method includes mixing the ZnCuO nanoparticles, a binding compound, and a conductive carbon compound in a solvent to form a suspension. Moreover, the method includes coating a substrate with the suspension and drying to form the electrode and the ZnCuO nanoparticles have an oval shape with an average size of 50 nm to 200 nm.

Abstract: A method for syngas production includes contacting an electrocatalytic working electrode with a gaseous electrolytic solution including carbon dioxide in a cell with a reference electrode and a counter electrode, applying a potential to the cell during the contacting, and forming a gaseous syngas product by electrocatalytically reducing the carbon dioxide in the gaseous electrolytic solution without forming any liquid syngas product. The electrocatalytic working electrode includes an electrocatalytic material on a conductive carbon paper. The electrocatalytic material includes a zeolitic imidazolate framework-8 (ZIF-8) and silver in an amount of 5 to 10 percent by weight of the electrocatalytic material. The ZIF-8 and silver are in a layer of particles. The particles are in the form of one or more polyhedrons and the one or more polyhedrons have a longest dimension with an average length of 0.1 to 20 μm. The electrocatalytic working electrode, the reference electrode, and the counter electrode are in connection with a potentiostat workstation.

Abstract: An europium doped Ni(BTC) Metal Organic Framework (MOF), Eu@Ni(BTC), as a sensor for detecting heteroaromatic compounds. Eu@Ni(BTC) shows selectivity towards thiophene and pyrrole with a detection limit of 0.2 and 8.4 ppm for thiophene and pyrrole, respectively. The sensor can be easily regenerated and can be used to analyze thiophene in water.
