Ethylene glycol-based solutions containing metal precursor chloride salts were investigated for the electrodeposition of cobalt thin films and nanowires. The electrochemical behavior of 0.5 M Co(II) chloride solution at 70 °C was studied by means of

Cu is the only electrocatalyst that converts CO2 into appreciable quantities of hydrocarbons. However, it usually suffers from poor catalytic stability. In this work we propose a strategy of introducing crystal defects to change the reaction pathway

The study of non-precious metal catalysts (NPMCs) as alternatives to platinum for oxygen reduction is crucial if the use of fuel cells is to become more widespread. Among NPMCs, pyrolyzed catalysts (Fe-N-C) are particul

Although often overlooked, current collectors play a significant role in the performance, safety, and stability of lithium batteries. Here we present a strategy to modify conventional Al current collectors using a conducting polymer, significantly de

To investigate the depth of charging at the material surface, batches of nickel hydroxide nanoparticles were hydrothermally synthesised in the range 3–450 nm. Any surfactant added was removed post synthesis using ozone. The capacity per gram (Cs) i

Template-based electrodeposition is a versatile technique for the fabrication of freestanding nanowires. However, nanowires of refractory metals, like niobium, have remained inaccessible via this technique due to preferential hydrogen evolution in aq

We present here for the first time the electrochemical behavior of germanium anodes in potassium-ion batteries (KIBs). Nanoporous germanium (np-Ge) samples were fabricated by the chemical-dealloying method using Al as the sacrificial metal. Galvanost

Here we report that the plasma-etching processed commercial titanium nitride (TiN-PE, PE represents plasma-etching) that was first treated by ball-milling method (TiNBM, BM represents ball-milling) is highly electrochemically active for the nitrogen
