摘要： Catalysts prepared from abundant, cost effective metals, such as cobalt, nickel, chromium, manganese, iron, and copper, and containing one or more neutrally charged ligands (e.g., monodentate, bidentate, and/or polydentate ligands) and methods of making and using thereof are described herein. Exemplary ligands include, but are not limited to, phosphine ligands, nitrogen-based ligands, sulfur-based ligands, and/or arsenic-based ligands. In some embodiments, the catalyst is a cobalt-based catalyst or a nickel-based catalyst. The catalysts described herein are stable and active at neutral pH and in a wide range of buffers that are both weak and strong proton acceptors. While its activity is slightly lower than state of the art cobalt-based water oxidation catalysts under some conditions, it is capable of sustaining electrolysis at high applied potentials without a significant degradation in catalytic current. This enhanced robustness gives it an advantage in industrial and large-scale water electrolysis schemes.

摘要： In order to carry out a selective extraction of cations (Mn+) by an electrochemical transfer in a solution from a first electrolyte (E1) to a second electrolyte (E2), the method includes using as an electrolyte separation wall a transfer wall (2) made of chalcogenide with molybdenum clusters (MonXn+2 or MxMonXn+2) and ensuring the cation transfer through the transfer wall by generating a potential difference (ΔE) between the electrode A1 in the first electrolyte (E1) and the electrode C2 in the second electrolyte (E1) or the transfer wall (2) in order to induce an intercalation of the cations in the transfer wall on the side of the first electrolyte, a scattering of the cations therein, and the de-intercalation thereof in the second electrolyte.

摘要： A method for removing a target compound from a liquid can include arranging two active surfaces so as to be separated by a distance. The active surfaces can be placed within a flow of the liquid and can be capable of supporting an electrical charge, biological growth, and/or enzymes and proteins. The method can further include developing a population of microorganisms concentrated on the active surfaces where the population of microorganisms is configured to or capable of transformation of the target compounds. The method can further include developing enzymes or proteins concentrated on the active surfaces where the enzymes or proteins are configured to or capable of transformation of the target compounds. The method can further include applying a potential difference between the two active surfaces. The microorganisms and the potential difference can be sufficient in combination and/or with specific nutrients to remove the target compound from the liquid and maintain the population of microorganisms. The enzymes and proteins and the potential difference can be sufficient in combination to remove the target compound from the liquid.
