As a renewable energy source, hydrogen production from biomass pyrolysis is one of the effective ways to promote global sustainable development. Herein, the inherent Al foils and typical LiCoO₂ cathodes in spent lithium ion batteries are jointly employed as the catalyst to reform sawdust pyrolysis gas to produce hydrogen-rich synthesis gas. It is the introduction of Al element that triggers the in-situ atomic replacement reaction to immobilize volatile lithium, thereby inducing the formation of a similar Li-CO₂ battery system, which efficiently converts CO₂ into CO. Furthermore, a new adsorption-enhanced in-situ-assembled porous structure has been discovered and proved to obtain ~95% surface vacancy oxygen content and various hydrogen evolution sites. Eventually, the yields and volume fractions of H₂ are 11.31 mmol/g and 65.79%, respectively, and the purity of syngas (H₂+CO) reaches 91.82%, which verify its excellent performance in hydrogen reforming and CO₂ conversion.

作为一种可再生能源，生物质热解制氢是促进全球可持续发展的有效途径之一。在此，废锂离子电池中固有的铝箔和典型的 LiCoO ₂阴极共同用作催化剂，将锯末热解气转化为富氢合成气。正是引入Al元素触发原位原子置换反应固定挥发性锂，从而诱导形成类似的Li-CO ₂电池体系，有效地转化CO ₂此外，还发现了一种新的吸附增强原位组装多孔结构，并证明可以获得~95% 的表面空位氧含量和各种析氢位点。最终，H ₂的产率和体积分数分别为11.31 mmol/g和65.79%，合成气（H ₂ +CO）纯度达到91.82%，验证了其在氢重整和CO ₂转化方面的优异性能。
