The increasing focus on carbon neutrality has spurred research into mitigating CO₂ emissions from energy-intensive industries, yet emissions from organic wastes and wastewater remain understudied. Electrochemical CO₂ reduction reaction offers a promising solution by converting waste-derived CO₂ into value-added chemicals. This study explores the synthesis of nickel single-atom catalysts using protein-rich wastewater as a cost-effective carbon matrix. Protein's ability to bind heavy metals, including nickel, enables the creation of stable nickel single-atom catalysts, which exhibit high selectivity for CO production. The research also addresses mass transfer limitations in traditional electrolysis by integrating Ni SACs into nanofibers via electrospinning to synthesize an integrated gas diffusion electrode. This approach not only converts waste-derived CO₂ into valuable products but also reclaims organic matters and heavy metals from wastewater, contributing to a closed carbon loop and potential negative emissions in wastewater treatment.

随着碳中和的关注度不断提高，推动了关于减轻能源密集型产业二氧化碳排放的研究，然而，有机废物和废水排放问题仍未得到充分研究。电化学二氧化碳还原反应通过将源自废物的二氧化碳转化为高附加值化学品，提供了极具前景的解决方案。本研究探索了以富含蛋白质的废水作为经济高效的碳基质来合成镍单原子催化剂的方法。蛋白质具有结合包括镍在内的重金属的能力，这使得合成稳定的镍单原子催化剂成为可能，该催化剂对一氧化碳的生成具有高选择性。研究通过静电纺丝法将镍单原子催化剂整合到纳米纤维中，合成一体化气体扩散电极，解决了传统电解过程中的传质限制问题。这种方法不仅能将源自废物的二氧化碳转化为有价值的产品，还能从废水中回收有机物和重金属，有助于形成闭环碳循环，并在废水处理中实现潜在的负排放。
