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.

我们面临全球气候变化危机。必须部署广泛的温室气体减排技术，以在本世纪末将全球变暖限制在 1.5 摄氏度。政府间气候变化专门委员会进一步强调了负排放技术的必要性，该技术可以消除大气中的二氧化碳。一种有前景的二氧化碳去除方法是直接空气捕获。在这种方法中，使用海绵状材料直接从空气中吸收二氧化碳。然后二氧化碳被收集并储存在地下，或用作化学构件。尽管这种方法很有前景，但除碳的相关成本仍然非常高，需要改进材料来降低该过程的成本。在这个项目中，我们将开发一种全新的类海绵材料，具有优异的性能，用于直接从大气中捕获二氧化碳。我们将开发一种新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吸收大量二氧化碳。令人兴奋的是，我们制备功能性海绵状材料的新策略最终将产生一个全新的材料系列，可应用于一系列节能化学过程。
