Charged Adsorbents for Capture of Carbon Dioxide Directly from Air

我们面临着全球气候变化危机。为了在本世纪末将全球变暖控制在1.5摄氏度以内，必须采用广泛的温室气体减排技术。政府间气候变化专门委员会进一步强调了对负排放技术的需求，这种技术可以从大气中去除二氧化碳。一种很有前途的二氧化碳去除方法是直接空气捕获。在这种方法中，二氧化碳是用一种类似海绵的材料直接从空气中吸收的。然后，二氧化碳被收集并储存在地下，或者用作化学构件。尽管这种方法很有前途，但碳去除的相关成本仍然很高，需要改进的材料来降低这一过程的成本。在这个项目中，我们将开发一种全新的海绵状材料，它具有优异的性能，可以直接从大气中捕获二氧化碳。我们将开发一种新的方法来制造这些材料，利用充电来调整材料成分并添加反应性化学基团。我们预测我们的新材料将能够直接从大气中结合大量的二氧化碳。令人兴奋的是，我们制备功能海绵状材料的新策略最终将导致一个全新的材料家族，应用于一系列节能化学过程。

We face a global climate change crisis. A wide range of greenhouse gas mitigation technologies must be deployed to limit global warming to 1.5 degrees celsius at the end of the century. The Intergovernmental Panel on Climate Change has further emphasised the need for negative emissions technologies, which remove carbon dioxide from the atmosphere. A promising approach for carbon dioxide removal is direct air capture. In this approach carbon dioxide is absorbed directly from the air using a sponge-like material. The carbon dioxide is then collected and stored in the ground, or used as a chemical building block. Despite the promise of this approach, the associated cost of carbon removal remains very high and improved materials are needed that can lower the cost of this process.In this project we will develop an entirely new class of sponge-like materials with excellent performance for the capture of carbon dioxide directly from the atmosphere. We will develop a new approach to make these materials that uses electric charging to tailor the material composition and add reactive chemical groups. We predict that our new materials will be able to bind large quantities of carbon dioxide directly from the atmosphere. Excitingly, our new strategy for preparing functional sponge-like materials will eventually lead to an entirely new family of materials with applications in a range of energy efficient chemical processes.
