We describe the spontaneous formation of composite chalcogenide materials that consist of two-dimensional (2D) materials dispersed in bulk and their unusual charge transport properties for application in hydrogen evolution reactions (HERs). When MoS2 as a representative 2D material is deposited on transition metals (such as Cu) in a controlled manner, the sulfidation reactions also occur with t...
Phosphorus-modified Pt@Cu (Pt/P@Cu) was fabricated through a one-step method as self-standing electrocatalyst, leading to increased surface activity sites, reduced charge transfer resistance and enhanced HER performance in neutral medium.
An active and stable hydrogen evolution electrocatalyst composed of MoO 2 surface nanorod arrays was prepared using high-temperature reductive annealing. Electrodes with an area 78.5 cm were evaluated in a three-cell AEM electrolyser stack.
Based on carbon materials, with the doping of various components, delicate structure design and morphology control, performance composite oxygen reduction electrocatalyst is continuously improved, its application prospect in Zn-air battery more promising.
One of the most important problems in development proton-exchange membrane fuel cells (PEMFCs) is selection an efficient support material to serve as electrocatalyst, which can ensure PEMFCs’ durability at low active metal loading, with minimal changes electrochemical surface and conductivity during long-term operations. Carbon nanostructures are now widely used PEMFCs such materials, including...
