 다운 oil의 공 Whatever the current offload society. Long time ago we could get the crude oil by simply digging in the ground. But now we can't do it anymore. Instead we should get it from deep sea. So apparently securing the crude oil is getting much more difficult. So crude oil has been used to produce fields and chemicals. All of the gasoline, diesel, jet fuel are from crude oil. Even fertilizer which contribute to food production greatly is also from crude oil. various chemicals, paints, rubber, fabric, and many plastics are also from crude oil. So all of these fuels and chemicals are produced in these mega-giant plants. Crude oil would get into the distillation tower and that the species are being separated. Liar species would come out at the top and heavier species at the bottom. And each species would undergo various further chemical processes. As crude oil has been depleted, 또한 이 fuels and chemicals 필요해야 하기 to produce all these fuels and chemicals. So chemical industries are actually looking for another way to produce these chemicals in a more sustainable way. So we can use biomass, hydrogen, solar power, or wind power for the sustainable production. So when we produce these chemicals, we need some special materials enabling all those chemical transformations which is nano-carolist. 이 나노캐라리스는 몇 년 동안 사용되었습니다. 그리고 지금 이 나노캐라리스의 기술을 정확히 조절할 수 있습니다. 그래서 5g의 플라틴 링을 사용합니다. 10nm의 플라틴 나노파레이콜이 10nm의 플라틴 링을 사용합니다. 7,600,000번의 플라틴 링을 사용할 수 있습니다. 이 플라틴 나노파레이콜의 플라틴 링을 사용합니다. 이 나노파레이콜의 플라틴 링을 사용하고 있습니다. 나노파레이콜의 모양은 이 깊은 화면이 전혀 흐뭇하고 있는 것이나 특별한 방법입니다. 나노캐라리스는 다양한 기술과 전체 기술에서 그 기술과 전체 기술을 사용하였습니다. 피orsilcar가 많은 대화가 받았지만 플라틴 링을 사용하는 너무 많은 것입니다. 그래서 나노파레이콜의 플라틴 링을 사용하고 플라틴 링을 사용하는 나노파레이콜의 그리고 플라틴이 사용되면 기술을 제공하고 있습니다. 그래서 플라틴이 사용되어 있는 기술을 제공하고 있습니다. 그래서 전통의 제공기술을 사용하는 기술은 2개의 기술을 제공하고 있습니다. 플라틴이 사용되면 수라세는 다이센서타이예요. 수라세는 자주 사용되네요. 수라세는 나노파리크를 쇼핑하는 various shapes of nickel-sulfide nanoparicers, which is much cheaper material were tested, and the rod shape showed even higher efficiency than platinum for the solar's conversion. 나노캐라 리스트는 또한 바이오메스 컨버전을 사용합니다. Ruthenium-on-carbon can convert cellulose into sorbitol. Previously, the toxic acid was used, but this material has no harm. In my group, we've developed that many nano-catalysts to produce high-value chemicals from biomass resources. New catalysts might be necessary to convert water and CO2 to various chemicals. The catalyst should be stable and active on the solar irradiation and also abundant and non-toxic. A lot of people are working on this solar fuel, including my own group, but no proper catalyst has been found yet. So I think we have the three options now. We can use that crude oil more efficiently, or we can use that many alternative technologies more actively, or we can try to develop something totally new. So we should seriously think what would be the best solution for sustainable production of fuels and chemicals now.
