Scientists From Russia And China Have Created An Inexpensive Material That Accelerates The Synthesis Of Hydrogen From Water
Scientists of Tomsk Polytechnic University (TPU) together with their Chinese colleagues were able to create catalysts (accelerators) based on molybdenum carbide, which will help to quickly obtain hydrogen from water - a promising environmentally friendly source of energy. Unlike analogs, catalysts for TPU researchers are much cheaper due to the creative technology and materials used, the press service of the University told reporters on Wednesday.
"Hydrogen is an environmentally friendly energy source. And the simpler, cheaper, and safer it can be generated, the faster hydrogen technologies will enter the energy industry. One of the options for producing hydrogen is to extract it from water using electrochemical methods. At the same time, various catalysts, usually based on platinum and palladium, are used to accelerate the reaction of water decomposition into hydrogen and oxygen. We suggested using instead of them molybdenum carbide with the addition of nitrogen," the words of one of the authors of the study, a graduate student of Tomsk Polytechnic University Yulia Vasilieva are quoted in the message.
It is specified that catalysts made of molybdenum carbide are much cheaper than traditional analogs made of platinum. The production technology also significantly affects their availability; for this purpose, specialists of Tomsk Polytechnic University have developed an installation for creating superhard materials based on carbides in a vacuum-free environment (in the open air). Accordingly, the process does not require expensive equipment and materials to create conditions with an inert gas environment, which is maintained so that materials do not burn.
"With the help of their installation, scientists get molybdenum carbide quickly enough - it takes less than 1 minute to produce 1 gram of the catalyst. The installation itself consists of simple elements: a power supply, a DC source, electrodes, and a control system," the report says.
It is also reported that thanks to TPU technology, it is possible to obtain inexpensive carbides for other purposes. For example, they are often used to create power electronics components, nuclear products, ceramic armor plates, and other products.
The hydrogen fuel cell is an environmentally friendly energy source with an almost inexhaustible resource. It generates electricity in an electrochemical reaction, the only byproducts of which are water vapor and heat. Unlike internal combustion engines, hydrogen systems do not have moving parts, so they have very high efficiency. Currently, China and Japan are planning to introduce hydrogen into the energy industry, as well as the EU countries, where they intend to achieve zero carbon emissions in their energy sector by 2050.
