The unprecedented co-thermolysis of decaborane(14) (nido-B H ) and toluene results in a novel porous material (that we have named "activated borane") containing micropores between 1.0 and 1.5 nm in diameter and a specific surface area of 774 m g (Ar, 87 K) that is thermally stable up to 1000 °C. Solid state H, B and C MAS NMR, UV-vis and IR spectroscopies suggest an amorphous structure of borane clusters interconnected by toluene moieties in a ratio of about three toluene molecules for every borane cluster. In addition, the structure contains Lewis-acidic tri-coordinated boron sites giving it some unique properties. Activated borane displays high sorption capacity for pollutants such as sulfamethoxazole, tramadol, diclofenac and bisphenol A that exceed the capacity of commercially-available activated carbon. The consistency in properties for each batch made, and the ease of its synthesis, make activated borane a promising porous material worthy of broad attention.
十硼烷（14）（巢式-B₁₄H₁₀）与甲苯前所未有的共热解产生了一种新型多孔材料（我们将其命名为“活性硼烷”），其具有直径在1.0至1.5 nm之间的微孔以及774 m² g（氩气，87 K）的比表面积，在高达1000 °C的温度下热稳定。固态¹H、¹¹B和¹³C MAS NMR、紫外可见光谱和红外光谱表明，硼烷簇的无定形结构由甲苯部分相互连接，每一个硼烷簇大约有三个甲苯分子。此外，该结构包含路易斯酸性的三配位硼位点，赋予其一些独特性能。活性硼烷对磺胺甲恶唑、曲马多、双氯芬酸和双酚A等污染物表现出高吸附容量，超过了市售活性炭的容量。每一批制备的产品性质的一致性以及其合成的简便性，使得活性硼烷成为一种值得广泛关注的有前景的多孔材料。
