Bisphenol A (BPA) has caused adverse effects on human health and natural environment as a poisonous endocrine disrupting chemical. In this study, the bimetal composite carbon material (Co&Ni/C) with carbon nanotubes was fabricated for BPA degradation by the catalytic pyrolysis method. The dense carbon nanotubes were observed on the carbon surface with a specific surface area of up to 265.68 m²/g. The cobalt oxide and nickel oxide were distributed evenly causing more catalytic sites. The factors affecting catalytic efficiency for degrading BPA by the peroxymonosulfate (PMS) and hydrogen peroxide (H₂O₂) systems were investigated and compared systematically. The Co&Ni/C showed better catalytic performance with a BPA degradation rate of nearly 80%–100% in the Co&Ni/C-PMS process. However, BPA was difficult to be removed completely by H₂O₂ with a mineralization efficiency below 40% under most reaction conditions. The different degradation pathways and mechanisms under the oxidation of SO₄^•− and HO• were also discussed respectively, and the intermediate reactions included radical adduct formation, hydroxylation, skeleton oxidation rearrangement, dehydration and ring cleavage. It was proved that the stable Co&Ni/C possessed good reusability for remaining 77% removal rate of BPA after a 4-stage adsorption-degradation reaction. This paper revealed that the synthetic Co&Ni/C was hopeful as the adsorption material with efficient catalytic activity to provide new insight into BPA in-situ degradation.

双酚 A (BPA) 作为一种有毒的内分泌干扰化学物质，对人类健康和自然环境造成了不利影响。在这项研究中，制备了具有碳纳米管的双金属复合碳材料 (Co&Ni/C)，用于通过催化热解法降解 BPA。在碳表面观察到致密的碳纳米管，比表面积高达265.68 m ² /g。氧化钴和氧化镍分布均匀，导致更多的催化位点。_{影响过氧单硫酸盐（PMS）和过氧化氢（H 2} O _{2 ）}降解BPA催化效率的因素) 系统进行了系统的调查和比较。Co&Ni/C 表现出更好的催化性能，在 Co&Ni/C-PMS 过程中 BPA 降解率接近 80%–100%。然而，在大多数反应条件下，BPA很难被H ₂ O ₂完全去除，矿化效率低于40%。_{SO 4}氧化下的不同降解途径和机制^{• -}和HO•也分别进行了讨论，中间反应包括自由基加合物形成、羟基化、骨架氧化重排、脱水和开环。事实证明，稳定的 Co&Ni/C 具有良好的可重复使用性，在经过 4 级吸附-降解反应后，BPA 的去除率仍为 77%。该论文表明，合成的 Co&Ni/C 有望作为具有高效催化活性的吸附材料，为 BPA 的原位降解提供新的见解。
