The electrodeposition of copper in the presence of a magnetic field has previously been shown to affect both electrochemical processes and the microstructure. In this work, we report a magnetically-induced anomalous second phase in thick films deposi

Electrochemical reduction of CO2 to value-added chemicals is a promising strategy for making use of excess CO2. Here, we synthesized a porous network zinc catalyst by electrodeposition of Zn(NO3)2 on Zn foil. The material exhibited excellent catalyti

Titanium-based porous transport layers (PTL) used in polymer electrolyte membrane (PEM) water electrolyzers suffer from surface passivation (titanium oxidation), which increases the interface resistance between the PTL and electrode. For long-term op

The Si@Ti3C2 MXene nanocomposite was prepared in this paper by simply ultrasonic mixing of commercially available nanosized Si and Ti3C2 MXene. The introduction of Ti3C2 makes the aggregation of silicon nanoparticles relieved. Electrochemical measure

Lithium ion batteries that are capable of extreme fast charging (XFC) are highly desirable to accelerate adoption of electric vehicles (EVs). To identify the rate limiting factors for XFC, we used both half cells and symmetric cells to investigate th

A new procedure employing infrared radiation to produce a nitrogen-containing highly porous carbon material based on polyacrylonitrile has been developed. The carbon material with a specific surface area of 1986 m2 g−1 demonstrated a specific capac

The performance of the Electro-Fenton (EF) process for contaminant degradation depends on the rate of H2O2 production at the cathode via 2-electron dissolved O2 reduction. However, the low solubility of O2 (≈1 × 10−3 mol dm−3) limits H2O2 prod

For the first time, lead film electrodes resistant to the action of oxidants commonly used to enhance the catalytic electrochemical response were deposited physically from a gaseous phase on thick film gold substrates and applied in catalytic adsorpt

We here demonstrate a high efficient phosphorus-iridium (P-Ir) electrocatalyst for oxygen evolution reaction (OER). The P-Ir particles show an atomic ratio of 2:1 (P:Ir) and a highly uniform size of 1.8–3.6 nm (>90%). Compared to the Ir nanoparticl
