My scientists successfully prepared a cheap and efficient electrolysis hydro-oxygen pre-production catalyst

 Reporter 15 from the University of Science and Technology of China was informed that the university Professor Wu Yuen team using innovative technology, in the oxygen analysis catalyst made a major breakthrough, for electrolytic water hydrogen industrialization to promote an important step, the results were selected as this month's "nature - catalysis" cover article.A key part of the "ultimate energy" hydrogen market is the efficient and inexpensive production of hydrogen. Among them, electrolyte water is one of the most popular preparation methods

. However, the highly efficient and inexpensive oxygenation catalysts necessary in the electrolysis process are one of the most difficult challenges facing the world today, with the "development of non-platinum oxygen reduction catalysts" and called the two holy grails in the field of hydrogen energy efficient utilization.commonly used commercial catalyst for the development of oxygen is palladium dioxide. The high price of palladium metal has become a major obstacle to the spread of high-energy, clean and inexpensive hydrogen energy. In contrast, palladium metal earth reserves are richer, cheaper, such as for industry, can effectively reduce the cost of hydrogen preparation. However, due to the strong acid, strong oxidation environment, palladium dioxide at a high level is very easy to be oxidized into palladium oxide, thus losing catalytic activity. Therefore, the development of a highly active and highly stable single-atom catalyst is the most promising way.stability of radon-based catalysts in acidic oxygenation is a recognized world problem. In order to achieve high-efficiency and low-cost electrolytic hydrocarbon production, the research team after many years of experimental exploration, innovatively proposed the use of antioxidant and anti-solubility ability of platinum-based alloy as a carrier, the use of surface defect engineering technology to capture and stabilize the method of single-atom successfully prepared a single-atom alloy catalyst, the single-atom alloy catalyst relative to commercial niobium-based catalyst reduced by about 30%, the stability increased by nearly 10 times.This achievement not only successfully realized the strategy of embedding single-atom palladium into stable alloy carriers to prepare an efficient catalyst, but also used metal/alloy carriers to regulate single-atom electron structures, which is expected to be applied to other reaction systems, providing ideas for many similar scientific problems and marking a major step towards a green future in which hydrogen can be widely used.
