Highly stable PtP alloy nanotube arrays as a catalyst for the oxygen reduction reaction in acidic medium

Abstract

Self-supporting PtP nanotube arrays composed of interconnected PtP alloy nanocrystals exhibited excellent activity and durability for the ORR in acidic medium.

Electrodeposition of (hydro)oxides for an oxygen evolution electrode

“…Most of these materials can be electrodeposited using template methods. Anodic aluminum oxide (AAO), [91][92][93] ZnO nanorods, 48,94 hydrogen/oxygen bubbles, [95][96][97] and polystyrene 69,98 have been widely used as templates. Electrodeposition ensures the uniform production of high-density 3D materials since it allows complete inlling of the space between the template spheres from the bottom to the top layers.…”

Nitrogen-Doped Porous Carbon Derived from Biomass Used as Trifunctional Electrocatalyst toward Oxygen Reduction, Oxygen Evolution and Hydrogen Evolution Reactions

“…Unfortunately, the high electrocatalytic activity of Pt is accompanied with several disadvantages, including high costs, sluggish kinetics, over potential and poor operational durability. Similarly, catalysts for OERs (IrO 2 and RuO 2 ) suffer due to high cost and the lack of long-term stability [14,15]. All these implications greatly hinder the efficiency of energy storage and conversion systems and their large scale applications.…”

Nanoconfined nitrogen-doped carbon-coated MnO nanoparticles in graphene enabling high performance for lithium-ion batteries and oxygen reduction reaction

“…Interest in developing high-performance and environmentally-friendly energy conversion and storage systems, such as lithium ion batteries (LIBs), metal–air batteries and fuel cells, has grown significantly since it is expected to be one promising strategy to tackle the global energy crisis and environmental pollution issues. 1 – 6 Of the energy conversion and storage systems, it is still a great challenge for LIBs to achieve high capacities, excellent cycling performance and rate capabilities for the growing power supply requirements. The most effective way to accomplish this objective is to shorten the diffusion path of the electrode materials or introduce a conductive buffering matrix.…”
