In the field of new energy science, hydrogen fuel is recognized as a clean energy source. However, currently, the way humans obtain pure hydrogen energy depends mainly on fossil fuels. Hydrogen can replace fossil fuels in order to minimize the greenhouse effect, but it also takes a lot of money to make hydrogen energy. Fossil fuels have made it difficult to understand the widespread use of hydrogen energy. Therefore, in order to reduce greenhouse gas emissions and develop renewable clean energy, it is inseparable from the method of decomposing water into hydrogen. Hydrogen is used as a raw material to produce various disadvantages of hydrogen, such as the high cost of auxiliary materials, too high reaction energy requirements, and the inability of synthetic catalysts to stably exist under realistic conditions. Plants have long learned how to break down water through photosynthesis, but humans have had to work hard to replicate this process. At present, 50 million tons of hydrogen are produced every year in the world, of which 95% comes from fossil fuels and hydrogen is produced by methane steam reforming. In the ordinary chemical reaction of decomposing water, the oxygen evolution reaction is notoriously slow, and dragging the legs to prepare hydrogen gas. Scientists have recently discovered for the first time a catalyst that is still effective under acidic conditions. This thin-film crystal catalyst can greatly increase the reaction efficiency and reduce the activation energy of the reaction, so that the hydrolytic hydrogen production plant will be just around the corner. “Although photolysis is very efficient in the decomposition of water, artificial reactions are no match at all.†Thomas Harami, Research Scientist at the Center for Interface Science and Catalysis, School of Chemical Engineering, Stanford University Thomas (Jamalemillo) said. Thomas and his colleagues have long devoted themselves to the development of catalysts for oxygen evolution in order to make synthetic catalysts last longer, catalyze faster reactions, or reduce the energy required for the reaction. These improvements can reduce the cost of the reaction, improve the efficiency of the reaction, and make the production of hydrogen more clean and efficient. The "Science" journal published the results of the team's research last week. The new catalysts they studied have low requirements for the environment, but their effectiveness is unprecedented. “The most important result of this study is that the catalyst we found can be stably present in the acid. Moreover, the catalyst's effectiveness has never been seen before.†Stanford scientists, the author of the above “Science†article, signed the author Hikata Yasuyuki. Evaluate this study. An important criterion for the oxygen evolution catalyst is the overpotential, which is the voltage required to start the reaction. The previous record was 320 millivolts, and this new catalyst reduced the overpotential required for the reaction to between 270 millivolts and 290 millivolts. Putian said that this new record can greatly increase the efficiency of the reaction and drastically reduce the energy consumption required for mass production of hydrogen. With this new catalyst, hydrogen plants are just around the corner. This promising catalyst is a thin-film crystal consisting of a layer of iridium oxide and a layer of Sr2IrO4 (strontium iridium oxide). Because thin-film crystals are flat and thin, it is easier for researchers to compare the effects of catalytic reactions. Erbium dioxide is the only type of catalyst found by humans that can be activated in acid. The research team also found that as the reaction progresses, the effectiveness of this catalyst is getting better. After measuring the catalyst, the researchers found that the surface of the catalyst has changed, but it has not been able to explain the specific mechanism of the catalyst. Scientists also admitted: "We don't yet know what's going on at the microscopic level. We only know that some of the helium ions leave the catalyst and go into solution." The research team is conducting further research, hoping to reduce the production costs of the catalyst, improve the catalytic effect, and also explore why the catalytic reaction is working so well. The price of oysters is very high, so they try to achieve the best results with the fewest blemishes. However, this kind of catalyst is still far from actual industrial production, and reducing the catalyst cost is the top priority of the research. “On the way to the development of the catalyst, we have only taken a small step and there is still a lot of room for improvement,†Thomas said. “One day, we may develop a catalyst that is millions of times better than it is today.
