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。

Researchers at ETH Zurich have engineered a catalyst using isolated indium atoms on hafnium oxide to convert CO2 and hydrogen into methanol more efficiently than previous methods. This single-atom design maximizes metal use and enables clearer study of reaction mechanisms. The breakthrough could support sustainable chemical production if powered by renewables.
A team at the University of Hong Kong has created a new stainless steel alloy that resists corrosion in seawater electrolysis. The material could replace expensive titanium components in hydrogen production systems.

Researchers at the University of Adelaide have devised a solar-powered process to transform plastic waste into clean hydrogen fuel and other chemicals. The technique, known as solar-driven photoreforming, uses sunlight and photocatalysts to break down plastics at low temperatures. Early experiments show promising hydrogen yields and system stability.
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.

Researchers at the University of Münster have developed a new technique that uses light to produce highly strained housane molecules. These compact structures could support advances in drug development and materials science.
Scientists at Nagoya University have developed an iron-based photocatalyst that reduces reliance on rare metals in organic synthesis. The new design uses fewer costly chiral ligands and enables the first asymmetric total synthesis of (+)-heitziamide A. This advance promotes more sustainable chemical reactions under blue LED light.

Researchers at IIT Delhi estimate that fully mitigating sulphur dioxide emissions from coal-fired power plants could prevent 1,24,564 deaths every year across India. The study, published in Nature this week, quantifies how these emissions contribute to both direct SO₂ levels and secondary PM2.5 formation. It also highlights uneven benefits that would favour lower-income and marginalised groups.
