近日，海南大学海洋清洁能源创新团队成功破解了长期制约的世界性难题，在甲烷直接催化转化领域取得颠覆性突破。

Recently, the marine clean energy innovation team of Hainan University has successfully solved a long-standing global problem and made a revolutionary breakthrough in the field of direct catalytic conversion of methane.

该团队研发的新型催化体系，以接近100%的完美选择性，在温和条件下将气态的甲烷高效转化为高附加值的液体燃料甲醇，为我国南海丰富的天然气水合物资源就地转化、高效利用提供了具有自主知识产权的核心技术方案。

The new catalytic system developed by this team, with an almost 100% perfect selectivity, efficiently converts gaseous methane into high-value liquid fuel methanol under mild conditions. This provides a core technology solution with independent intellectual property rights for the local conversion and efficient utilization of the abundant natural gas hydrate resources in the South China Sea of our country.

相关研究成果日前在国际学术期刊《自然·通讯》杂志上发表。

The relevant research results were recently published in the international academic journal "Nature Communications".

天然气水合物（可燃冰）是蕴藏在中国南海的巨大战略能源宝库，其主要成分甲烷，然而甲烷分子结构异常稳定，传统的工业利用方式如同“大火猛攻”，需在高温高压下进行粗放式转化。因此，如何在温和条件下实现原子级的精准调控，将甲烷直接、高效地转化为甲醇，一直是全球催化化学领域的“圣杯级”挑战。

Natural gas hydrates (flammable ice) are a huge strategic energy reserve buried in the South China Sea of China. Their main component is methane. However, the methane molecule structure is extremely stable, and traditional industrial utilization methods are like "intense and fierce attacks", requiring extensive conversion under high temperature and high pressure conditions. Therefore, how to achieve precise atomic-level control under mild conditions and directly and efficiently convert methane into methanol has always been a "sacred cup-level" challenge in the field of global catalytic chemistry.

海南大学海洋清洁能源创新团队巧妙地设计出一种纳米级别的钯（Pd）催化剂，通过对晶面的精密“装修”，能够精准识别并激活甲烷分子。更关键的是，它对目标产物甲醇具有一种“快速释放”的特性：一旦宝贵的甲醇分子生成，催化平台会立即将其“弹出”，避免其在反应环境中停留过久而被过度氧化。

The marine clean energy innovation team of Hainan University ingeniously designed a nano-scale palladium (Pd) catalyst. By precisely "decorating" the crystal surfaces, it can accurately identify and activate methane molecules. What's more crucial is that it has a "rapid release" characteristic for the target product, methanol: once the precious methanol molecules are generated, the catalytic platform will immediately "release" them, avoiding their prolonged stay in the reaction environment and being overly oxidized.

据悉，这项突破性技术实现了两大创新，一是根据最终实验结果显示，甲醇的选择性高达99.7%，几乎实现了“零损耗”的完美转化；二是整个过程仅需70℃的低温，这意味着未来的工业化生产将更安全、更节能、更环保，具备了极高的商业应用潜力和经济价值。

It is reported that this groundbreaking technology has achieved two major innovations. Firstly, according to the final experimental results, the selectivity of methanol is as high as 99.7%, achieving a perfect conversion with almost no loss. Secondly, the entire process only requires a low temperature of 70℃, which means that future industrial production will be safer, more energy-efficient, and more environmentally friendly, and has extremely high commercial application potential and economic value.
