  • Copper–chlorine cycle Wikipedia

    The copper–chlorine cycle (Cu–Cl cycle) is a four-step thermochemical cycle for the production of hydrogen. The Cu–Cl cycle is a hybrid process that employs both thermochemical and electrolysis steps. It has a maximum temperature requirement of about 530 degrees Celsius. The Cu–Cl cycle involves four chemical reactions for water splitting, whose net reaction decomposes water into hydrogen and oxygen. All other chemicals are recycled. The Cu–Cl process can be linked with nucle

    20/8/2010· An example is the electrolysis of copper(II) chloride, CuCl 2. Here the copper ions are the positive ions. When current is applied to the solution, they will, therefore, move towards the cathode where they are reduced in the following reaction: Cu 2+ + 2e--> Cu. This will result in a copper plating around the cathode. At the positive anode, the
