Manganese Nano Oxides Show Self-repair Properties in New Study نویسنده: Albert Iranian researchers discovered new self-repair properties in manganese nano oxides during a study on the stability of these materials in media containing oxidants. Manganese oxides were used to be known as instable materials in oxidative environments. Manganese nano oxides can be used as catalyst in water oxidation reaction to produce hydrogen as green fuel. The self-repair properties of these particles decrease the cost of the production of green fuel. Dr. Mohammad Mehdi Najafpour, a member of the Scientific Board of Institute for Advanced Studies in Basic Sciences, elaborated on the research. “In order to obtain a catalyst with self-repair properties, we chose a type of manganese oxide that has a very reasonable price and is synthesized very easily. These materials lose their active sites after a while. In other words, they are damaged. By precisely studying the separated sites, we realized that the se
