摘要： A method of ammonia synthesis is described that includes contacting a nitrogen gas-containing plasma with an aqueous solution, thereby forming ammonia from the nitrogen gas and water. The nitrogen gas-containing plasma is present in an electrochemical cell. The electrochemical cell includes a container including an acidic liquid electrolyte. The electrochemical cell also includes a source of nitrogen gas, a metal electrode at least partially immersed in the electrolyte, a metal tube electrode spaced apart from a surface of the electrolyte by a predetermined spacing. The electrochemical cell is configured to provide a plasma spanning the predetermined space from the metal tube electrode to contact the surface of the electrolyte when power is applied to the metal tube electrode.

摘要： A method of electrocatalytic water splitting by providing an anode and a cathode; and utilizing the anode and the cathode for alkaline water electrolysis. Each of the anode and the cathode comprises a uniform distribution of a bifunctional electrocatalyst comprising metallic phosphides on a conductive substrate. The metallic phosphides comprise arion phosphide (FeP) and dinickel phosphide (Ni2P). The bifunctional electrocatalyst promotes hydrogen evolution reaction (HER) at the cathode, and oxygen evolution reaction (OER) at the anode.

摘要： An electrode structure includes an electrolyte membrane, a catalyst layer, a porous layer, and an ionomer layer. The catalyst layer is formed on a surface of the electrolyte membrane. The porous layer is stacked on an external side of the catalyst layer. The ionomer layer is interposed between the catalyst layer and the porous layer. Thus, it is possible to reduce electrical contact resistance between the catalyst layer and the porous layer.

摘要： Electrocatalytic overall water splitting to generate hydrogen and oxygen is a green and sustainable approach with zero carbon emission, which is important for the future renewable energy landscape. The practical application of this approach is challenging due to the sluggish reaction kinetics of water activation at high current densities, which are hard to overcome. Although high-performance alkaline bifunctional electrocatalysts may be useful, current catalysts lack both activity and durability. One approach is to rationally design bifunctional two-dimensional (2D) heterostructures but obtaining an efficient and durable catalyst has proved difficult. The present disclosure relates generally to an electrocatalyst including a 2D heterostructure (Ru-CMOP), methods of making and using the same. The catalyst of the present disclosure is designed for high activity and good durability at industrial-level high current densities.
