摘要

气候变暖的加速需要快速降低大气中二氧化碳含量的方法。在这里，我们利用四个磁控管依次对钛屑发射微波，将二氧化碳转化为碳化钛。二氧化碳分子在等离子体中离解，与电离的钛原子发生反应，形成稳定的碳化钛产品，每个磁控管的微波频率为 2.3 千兆赫，功率为 800 瓦。结果显示，二氧化碳浓度在 30 秒内从 2000ppm 降至 385ppm。

Rapid conversion of carbon dioxide into titanium carbide by atmospheric microwave plasma

The accelerating climate warming requires fast methods to reduce atmospheric carbon dioxide levels. Here, we converted carbon dioxide into titanium carbide using four magnetrons which were sequentially operated to emit microwave on titanium swarf. Carbon dioxide molecules dissociated in the plasma to react with ionized titanium atoms to form a stable titanium carbide product, using a microwave frequency is 2.3 gigahertz and 800 watts electrical power for each magnetron. Results show a reduction of carbon dioxide concentration from 2000 to 385 ppm within 30 s. Titanium carbide could be further functionalized as a three-dimensional printed gas sensor.

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
