Manipulating Ru oxidation within electrospun carbon nanofibers to boost hydrogen and oxygen evolution for electrochemical overall water splitting

Abstract

Developing bifunctional high-efficiency electrocatalysts with prominent durability toward overall water splitting is a fascinating way to produce hydrogen for clean energy application. In this work, partially oxidized Ru nanoparticles integrated...

Rhenium anchored Ti3C2Tx (MXene) nanosheets for electrocatalytic hydrogen production

“…Notably, recent work showed that a combination of metallic and partially oxidized Ru nanoparticles is beneficial for overall water splitting reactions including the HER. 35 Therefore, it is reasonable to expect that the presence of both metallic and oxidized Re would be valuable to enhance the catalytic activity of the catalyst.…”

Exploring Enhanced Electrocatalytic Hydrogen Evolution by Metal‐Free Highly Conjugated Azomethine‐Functionalized Graphitic Carbon Nitride

“…Preferably, a very low overpotential as well as significantly less Tafel slopes were needed for effective HER performance. [ 25 ] The HER performance of the electrode was characterized by LSV at a scan rate of 50 mV s −1 to rule out any prospective contributions from capacitive current. EIS was employed to measure the Ohmic resistance of the electrocatalytic system.…”

Construction of a phosphorus-based integrated electrode for efficient and durable seawater splitting at a large current density

“…38 A lack of peaks corresponding to Ru compounds was also present in the XRD pattern, which indicated that no new crystalline phases were generated during sample preparation, suggesting that the constructed P and Ru materials mainly exist in an amorphous and weakly crystalline state. [39][40][41] The Ru@P-NF electrode was further characterized by high-resolution scanning electron microscopy (HR-SEM, Fig. 1b-d).…”
