摘要： The present invention relates to a method for producing an electrode for alkaline electrolysis based on a composition of sulfides on a Ni foam substrate. In a step. S2) there is performed a sulfiding on the Ni substrate. The step of sulfiding results in the formation of electrocatalytic active nano-sites with Ni—S compounds. It is found that these nano-sites are capable of reducing the so-called overpotential of the electrodes during alkaline water electrolysis, and the production of electrodes may be significantly simplified. In particular, already existing electrolyzer units may benefit from this invention by on-site application of the improved method.

摘要： Provided are a novel nickel foam having a hierarchical pore structure, a method of producing the same, and an application thereof. Unlike a conventional nickel foam, the nickel foam has a well-developed hierarchical pore structure including pores having a size of 4 μm or less in addition to inherent macropores having a size of 100 μm to 900 μm, and thus, may have a significantly large specific surface area. Accordingly, the nickel foam may be variously applied to an electrochemical reaction such as a water electrolysis system and an exhaust gas purification filter.

摘要： Proposed are a method of preparing a metal nanostructure, which includes (a) preparing a first metal template whose surface is coated with a polymeric micelle containing an amphiphilic polymer and (b) causing the first metal template to react with a second metal ion through a galvanic replacement reaction, and a metal nanostructure prepared thereby. The amphiphilic polymer is used as a capping agent during the replacement reaction so that the micellar polymer is adsorbed onto the template, thereby selectively allowing the replacement reaction. Thus, unlike in existing technologies in which nanostructures having limited forms are prepared, nanostructures having a new two-dimensional structure, including nanostructures having a plurality of pores formed between nanoparticles, can be prepared. Additionally, a mixing ratio of two types of solvents that differ in polarity index is adjustable to control the size of the polymeric micelle, thereby changing the structural characteristics of a finally prepared metal nanostructure.

摘要： Disclosed herein are systems, methods and compositions of matter for engineered formate dehydrogenases electrocatalytically driven in reverse to fix CO2 to formate, an electrode interface composed of self-assembled monolayers (SAM), and a nanowire link between the electrode and the enzyme's iron sulfur (FeS) cluster (engineered) to specifically link the iron sulfur cluster to the electrode. Engineering the interface between the enzyme and the electrode enables a high degree of activity and function compared to just an enzyme immobilized on the electrode. This interface enables specific orientational control of the enzyme and allows for separation of the enzyme from the electrode surface to allow retention of its native hydrodynamic radius. The transfer of electrons via the nanowire to the FeS cluster allows the enzyme to utilize its native electron transfer pathways. Moreover, wiring the FeS cluster directly to the electrode avoids the kinetic bottleneck of a soluble mediator and thus allows the wired enzyme to function more efficiently.
