However, it has been mainly produced by separating it from fossil fuels such as coal, oil, and natural gas as it only exists in the form of water or organic compounds. While this method is low in price for manufacturing cost, it also has a disadvantage in that it emits greenhouse gas and causes environmental pollution during the production process.</span></p> <p><span style="font-size: 10pt; font-family: arial,helvetica,sans-serif;">In contrast, the manufacturing process of hydro electrolytic technology is eco-freindly since it produces hydrogen by electrically decomposing water. As of the current technology, hydro electrolytic production is only feasible with high-priced metal-based catalysts, thus, the development of high-efficiency and low-cost catalysts is necessary for commercialization.</span></p> <p><span style="font-size: 10pt; font-family: arial,helvetica,sans-serif;">Professor Han's team developed an original technology that can simultaneously form nickel boride(Ni₂B) showing great electrical conductivity as well as nickel hydroxide(Ni(OH)x) with an advantage of adsorbing reactants by applying chemical etching process on the catalyst surface to improve the efficiency of hydro electrolytic catalysts. With this technology, his team suggested a new catalyst material design paradigm with excellent electrical conductivity and adsorption function for the catalyst surface.</span></p> <p><span style="font-size: 10pt; font-family: arial,helvetica,sans-serif;">The use of the newly developed catalyst will increase the production efficiency of hydrogen for about 10% while maintaining the durability corresponding to metal catalysts. The price of the catalyst is expected to be reduced by about 40% compared to the existing ones.</span></p> <p><span style="font-size: 10pt; font-family: arial,helvetica,sans-serif;">Professor Han said, “The technology is applicable not only for hydrogen catalysts but for energy conversion and storage devices such as batteries, fuel cells, super-capacitors, and so on.” adding, “It will contribute to leading the Green New Deal business including the creation of hydrogen business and revitalization of hydrogen economy.”</span></p> <p><span style="font-size: 10pt; font-family: arial,helvetica,sans-serif;">*Super-Capacitor: a capacitor that temporaily stores electricity in an electronic circuit</span></p> <p><span style="font-size: 10pt; font-family: arial,helvetica,sans-serif;">The research results were selected and published online as the cover of ‘Advanced Functional Materials(Impact Factor: 16.836)’, a renowned overseas journal in the field of material, in September 2020.</span></p> <p><img style="margin-left: auto; display: block; margin-right: auto;" alt="" src="ArticleFile.do?id=11798490" width="630" height="828" /></p>
