Detailed explanation-1: -Water splitting is the process in which water decomposes into hydrogen and oxygen. Doing so by passing an electric current through water is called the electrolysis of water.

Detailed explanation-2: -In a process called photolysis (’light’ and ‘split’), light energy and catalyst s interact to drive the splitting of water molecules into protons (H+), electrons, and oxygen gas.

Detailed explanation-3: -Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules.

Detailed explanation-4: -Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called an electrolyzer.

Detailed explanation-5: -In thermolysis, water molecules split into their atomic components hydrogen and oxygen. For example, at 2200 °C about three percent of all H2O are dissociated into various combinations of hydrogen and oxygen atoms, mostly H, H2, O, O2, and OH.
