New Water Electrolysis Doubles Hydrogen Production Efficiency

New Water Electrolysis Doubles Hydrogen Production Efficiency

An international team of scientists has developed a new method for extracting hydrogen from water using electric current, requiring half the amount of electricity.

The principle of electrolysis has been known to everyone since school,but due to the growing popularity of "green" energy and alternative fuels, many researchers began to search for more effective methods of electrocatalytic fission. A team of scientists from several universities in the UK, Portugal, Germany and Hungary has made significant progress in this direction.

They published an article describing how toUsing a special scheme for supplying strong current pulses passing through electrodes coated with a layered molybdenum telluride (MoTe2) catalyst, the amount of hydrogen produced per unit of expended energy can be significantly increased.

By optimizing the current pulses through an acid electrolyte, the researchers were able to almost 50% reduce the amount of electricity needed to produce a given amount of hydrogen.

The crystal structure and polyhedrons of the building blocks of each polymorph.

According to scientists, applying machine learningYou can determine the optimal pulse sequence setting for maximum performance. Therefore, the next step in their work will be the development of an artificial intelligence protocol that will search for the most efficient electronic structures for such catalytic processes.

Recall that in March, researchers alsoimproved the technology of electrolysis of sea water by developing a coating for the anode, which protects the metal from the harmful effects of chlorine and increases the efficiency of the system.
