When an electric current is applied, water reacts at the cathode by forming hydrogen and negatively charged hydroxide ions, which diffuse through the barrier to the anode to produce oxygen.

Water molecules can break down into hydrogen ions and hydroxide ions. \(H_{2}O(l)\rightleftharpoons H^{+}(aq)+OH^{-}(aq)\) This is a reversible reaction. A small proportion of water molecules ...

Acids produce hydrogen ions whereas bases remove them. Bases do this by producing hydroxide ions (OH-) which work to neutralise hydrogen ions. It is the ratio of hydrogen ions to hydroxide ions ...

Researchers have developed a revolutionary catalyst that dramatically boosts the efficiency and affordability of green ...

The electrodes create positive hydrogen ions and negative hydroxide ions by splitting water between two layers rather than by introducing a chemical base to induce this charge. By binding with ...

Instead of adding a base, the charge is created by splitting water between two electrodes, creating positive hydrogen ions and negative hydroxide ions. The hydroxide attaches to boron, giving it a ...

Especially if your end goal is to create liquid hydrogen when everything ... with pure water, sodium hydroxide (NaOH) is used in the solution to provide the ions. The electrodes are made of ...

Here, the authors report a self-assembly technique to synthesize atomically thin high-entropy oxides from the assembly of naked metal ions ... hydrogen and oxygen in separate cells. Hydroxide ...

Researchers in Korea have successfully developed a new material that significantly enhances the efficiency of green hydrogen ...
