What are solar-driven electrochemical water splitting cells?

Solar-driven electrochemical water splitting cells, known as photoelectrochemical (PEC) cells, with integrated photoelectrode (s) that directly convert solar to chemical energy via generation of solar hydrogen fuels, have also been studied and developed extensively.

How does a porous solid state electrolyte reactor work?

The porous solid-state electrolyte reactor utilizes a middle chamber filled with solid-state electrolyte catalysts, two ion exchange membranes and catalysts to oxidize water into protons at the anode and reduce oxygen or carbon dioxide at the cathode, producing hydrogen peroxide, formic acid, or acetic acid, all powered by renewable solar energy.

Can solar-driven electrolysis produce value-added chemicals?

Solar-driven electrolysis can produce value-added chemicals through less energy-intensive processes. This Review examines the fundamentals and economics of different electrochemical approaches powered directly or indirectly by sunlight and alternative reactions that replace O2 evolution and integrate downstream utilization of H2.

Why do water based electrolytes have a higher cell potential?

Cells using water-based electrolytes are usually limited to cell potentials less than about 2.5 volts due to high reactivity of the powerful oxidizing and reducing agents with water which is needed to produce a higher voltage. Higher cell potentials are possible with cells using other solvents instead of water.

Will solar-driven water electrolysis increase the economic return?

Coupling chemical production into solar-driven water electrolysis is expected to increase the economic return due to the co-production of H 2 and valuable chemicals, irrespective of the configurations.

What is an electrolytic cell?

An electrolytic cell is an electrochemical cell in which applied electrical energy drives a non-spontaneous redox reaction. A modern electrolytic cell consisting of two half reactions, two electrodes, a salt bridge, voltmeter, and a battery. They are often used to decompose chemical compounds, in a process called electrolysis.
