中国科研人员最近在硫化氢处理技术上取得突破，为化工行业提供更可持续的解决方案。该技术由中国科学院大连化学物理研究所开发，已于周二通过验证。
硫化氢是一种高度毒性的化合物，常作为天然气开采、炼化以及煤化工生产过程中的副产物产生。化工行业长期面临完全去除硫化氢并实现资源利用的挑战。
经过20多年的研究，大连化学物理研究所的团队探索了光解和电化学方法来分解硫化氢，解决了大规模硫化氢分解工程的规模化问题。该技术目前正应用于一个煤化工示范项目，该项目每年针对10万立方米的硫化氢进行消除和资源利用。数据显示，硫化氢的转化率接近100%，从而生产出高质量硫和纯度高的氢气。
中国科学院院士、大连化学物理研究所研究员李灿向中国媒体集团表示：“中国许多天然气井因硫化氢含量高而无法开采。有了这项技术，我们可以解决环境和生态问题，同时生产氢气和硫。”
李灿补充道：“特别是氢气可以安全、低成本、大规模生产。它可以直接用于燃料电池，甚至在航空航天等行业。”
这项突破有助于解决中国天然气资源的开发限制，并促进清洁能源的生产，推动化工行业的可持续发展。

中国研究人员开发了一种受光合作用启发的太阳能驱动过程，将二氧化碳和水转化为用于汽油生产的化学物质。这种方法使用一种新型材料存储电能，以高效驱动化学反应。这一突破可能为航空和航运等部门提供燃料。
Commercialisation of hydrogen fuel cell trucks in China has revived optimism in the platinum industry. Northam Platinum CEO Paul Dunne highlighted a Chinese company's fleet of over 20,000 trucks, each using 100 grams of platinum. The development was discussed at a recent PGM conference in Johannesburg.

Researchers conducted a trial in the Gulf of Maine, pouring 65,000 litres of sodium hydroxide into the ocean in August 2025, which removed up to 10 tonnes of carbon dioxide from the atmosphere. The experiment, the first ship-based alkalinity enhancement test, showed no significant impact on marine life. Initial findings were announced at the Ocean Sciences Meeting in Glasgow on 25 February.
Governor Gretchen Whitmer has directed state agencies to assess regulations for drilling geologic hydrogen, a potential clean fuel buried beneath Michigan. A recent U.S. Geological Survey study highlights the state as a promising location due to its geological features. Experts see it as a way to reduce emissions in hard-to-decarbonize sectors like shipping and trucking.
