Published: April 2024

Hybrid water electrolysis (HyWES) with iodide oxidation as non-OER for energy-saving H production is demonstrated using self-supported sulfate ion modified Ni,Fe(oxy)hydroxide as the anode. The sulfate ions adsorbed on the catalyst show a promoting effect in achieving high electrochemical activity. The HyWES requires a voltage as low as 1.36 V to achieve the bechmark current density of 10 mA cm.

The key component of electrochemical advanced oxidation technology are high-efficiency anodes, and highly efficient and simple-to-prepare materials have generated a lot of interest. In this study, novel self-supported Ti-doped titanium dioxide nanotube arrays (R-TNTs) anodes were successfully prepared by a two-step anodic oxidation and straightforward electrochemical reduction technique. The electrochemical reduction self-doping treatment produced more Ti sites with stronger absorption in the UV-vis region, a band gap reduction from 2.

A self-supporting catalyst consisting of 1D/2D vertical molybdenum disulfide@titanium dioxide/nitrogen-doped carbon nanofiber (MoS@TiO/NCNFs) was prepared and tested. It showed efficient hydrogen peroxide (HO) decomposition to generate hydroxyl radical (OH) and degradation of various pollutants under solar irradiation. The contribution of the increase in MoS edges for decomposing HO was 0.

Nickel hydroxide is promising for use in supercapacitor applications because of its low cost and tunable electrochemical properties, but its performance is usually restricted by insufficient conductivity and surface reactivity. In this work, sulfate-functionalized Ni(OH) (SNO) nanoplates were grown in situ on nickel foam (NF) by a green and facile one-step hydrothermal treatment of NF without the need for an external Ni source or surfactant addition. The resulting material showed a 9.

Highly active electrocatalysts made of earth-abundant elements are vital for efficient and cost-effective energy storage and conversion systems. In this communication, we report the further amorphization of a solvothermally synthesized dodecyl sulfate anion-intercalated cobalt hydroxide nanosheet array on nickel foam (DS-Co(OH)2/NF) via pyrolysis. Owing to the greatly enlarged interlayer distance of the DS-Co(OH)2/NF precursor (2.
