    來自中國和丹麥的研究人員表示，他們已經在如何利用電力將二氧化碳轉化為原材料方面邁出了重要的一步，這個過程可以極大地促進減少碳排放。
    Researchers from China and Denmark say they have worked out an important step in how to turn carbon dioxide into a raw material using electricity – a process that could dramatically boost efforts to reduce emissions.
 
    2022年2月17日發表在《自然通訊》期刊上的一篇論文中提到，科學家們表示，他們比以前更清楚地確定如何將電化學還原二氧化碳（CO₂）變成可能的。
    In a paper published in the peer-reviewed journal Nature Communications on Thursday, the scientists said they had established more clearly than before how electrochemical reduction of carbon dioxide (CO2) is made possible.
 
    電化學還原是將二氧化碳（CO₂）轉化為單碳產物，例如一氧化碳（CO）和甲酸鹽（HCOO）。它是一種將溫室氣體轉化為化學品和燃料附加價值的方法。
    Electrochemical reduction is the conversion of CO2 to single-carbon products such as carbon monoxide and formate. It could offer a way to turn greenhouse gases into value-added chemicals and fuels.
 
    研究的合作者，丹麥技術大學副教授布賴恩·西格（Brian Seger）表示：「這不是第一項工作，但我認為這可能是解釋反應機制最清晰的工作，我們現在需要做的是設計一種更高效的催化劑。」
     “This isn’t the first work, but I think this is probably the clearest work [in explaining the reaction mechanism],” said Brian Seger, co-author of the study and an associate professor at the Technical University of Denmark. “What we need to do now is to design a more efficient catalyst.”
 
    捕獲、儲存和使用二氧化碳（推動全球氣候變遷的關鍵溫室氣體）的能力可以幫助各國實現淨零排放目標。
    The ability to capture, store and use carbon dioxide – the key greenhouse gas that drives global climate change – could help countries to reach net-zero emissions targets.
 
    但至今為止，只有少數公司開發出將溫室氣體轉化為原材料的技術。
    But only a few companies have so far developed the technology to turn the greenhouse gas into a raw material.
 
    二氧化碳可以轉化為液體燃料或化學品。與需要高溫高壓的傳統轉化方法比較，電化學還原過程可以在室溫下進行，並由電力驅動。
    Carbon dioxide can be converted into liquid fuels or chemicals. Compared with traditional CO₂ conversion, which requires high temperature and pressure, the electrochemical reduction process can be performed at room temperature and powered by electricity.
 
    該研究顯示，電化學還原二氧化碳作為新興資源具有巨大的潛力。
    It had great potential as an emerging approach to using CO2 as a resource, the study said.
 
    布賴恩·西格（Brian Seger）表示：「我們可以從風力發電機或太陽能電池中獲取二氧化碳和電力的想法，這是一種永續的方法來生產塑膠和其他含有碳的產品。」他也補充說明，要實現這個目標，必須使用高效催化劑將二氧化碳轉化為一氧化碳。
    “The idea of taking CO2 with electricity, which we can get from wind turbines or solar cells, is to have a sustainable way to produce plastics and other products that we use that have carbon in them,” Seger said. To achieve that, carbon dioxide must be converted to carbon monoxide using an efficient catalyst, he added.
 
    然而，目前其反應機制尚未明確，中國及丹麥的研究團隊仍試圖釐清中。
    However, the reaction mechanism is not well understood, which the Chinese-Danish study sought to address.
    該研究總結道：「我們期待這項發現能夠成為並改善二氧化碳的電化學還原的領導趨勢。」
    “We expect this finding to provide guidance for improving electrochemical reduction of CO₂,” the study concluded.
 
    美國國營《科學日報》援引該研究的主要作者，天津大學博士生鄧萬宇的話說：「研究結果為反應機制提供了新的見解。」
    State-run Science Daily quoted Deng Wanyu, lead author of the study and a PhD student at Tianjin University, as saying “the results provide new insights into the reaction mechanism”.
 
    布賴恩·西格（Brian Seger）表示，「該計畫在外來可能會實際應用，我們的目標是我們試圖擴大東西，我們理解這個機制，我們能否利用我們獲得的知識製造一種可以出售給公司的設備」。
    Seger said that the project could lead to real-world applications. “One direction is we are trying to scale this stuff up,” he said. “We understand this [mechanism]. Can we make a device that we can sell to the companies using the knowledge we gain?”
 
    布賴恩·西格（Brian Seger）並補充說，這項技術已開始從實驗室轉移到小型新創公司手中。
    The technology was starting to move beyond the laboratories into the hands of small start-up companies, he added.
 
    2020年，德國化學品公司贏創工業（German speciality chemicals firm Evonik）與西門子能源股份有限公司（Siemens Energy）一起委託建造了一個試範工廠，該工廠使用二氧化碳和水生產化學品。
    In 2020, German speciality chemicals firm Evonik, along with Siemens Energy, commissioned a pilot plant that used carbon dioxide and water to produce chemicals.
 
    據西門子能源股份有限公司稱，綠色能源被用於將二氧化碳和水轉化為由一氧化碳和氫氣組成的氣體，然後將其轉化為己醇和丁醇等化學物質。
    The German Federal Ministry of Education and Research contributed funding.
Green power was used to turn CO2 and water into a gas consisting of carbon monoxide and hydrogen, which was then converted into chemicals such as hexanol and butanol, according to Siemens Energy.
