摘要

工業含碳基廢棄物及生物質(bio-mass)的轉化研究近年來引起了廣大的注意，其中以廢輪胎或生物質廢棄物可經由熱裂解後通過物理活化法(steam/CO_2)或化學活化法(KOH、H_3PO_4、NaOH)途徑轉化為活性碳。本文統整介紹近幾年來廢輪胎及各種農業生物質廢棄物再活化成為具有高孔洞結構的活性碳並利用在水中有機染劑的吸附、儲能的超級電容及水中中金屬的去除等應用，這些研究成果不僅為活性碳的製備來源找到解決方案，更可以將原本會造成環境物染的廢棄物找到再活化的途徑。

Transformation of industrial waste carbon-based materials and biomass are attracted greatly interest in academia and industrial owing to several potential applications. These also depict promising routes for resolving environmental impact from the above-mentioned wasted materials. Physical or chemical activations are usually employed for transforming scrap tire and biomass into activated carbons (AC) with high specific surface area and porous structures. The former is proceeded by steam or carbon dioxide; the latter is completed with several chemicals, e.g. KOH, H_3PO_4, NaOH, etc. Here, we systematically introduce recent advancements of AC derived from scrap tire and agricultural biomass and their applications in dye adsorption, supercapacitors, and heavy metal removers. These studies not only give new concepts for looking new precursors of AC, but also provide promising ways to save our planet in reducing environmental wastes.
