Nature – Zhu et al. (2024): Artificial cellulosic leaf with adjustable enzymatic CO2 sequestration capability

Xing Zhu, Chenxi Du, Bo Gao, Bin He IN: Nature Communications, 15,

In this study, the authors introduce EcoLeaf, an artificial leaf that closely mimics the characteristics of natural leaves. It harnesses visible light as its sole energy source and orchestrates the controlled expansion and contraction of stomata and the exchange of petiole materials to govern the rate of CO2 sequestration from the atmosphere. Furthermore, EcoLeaf has a cellulose composition and mechanical strength similar to those of natural leaves, allowing it to seamlessly integrate into the ecosystem during use and participate in natural degradation and nutrient cycling processes at the end of its life.
