以杨絮(PC)为原料，采用乙醇溶剂热法对其进行预处理，再进行碳化，制备了高比表面积的杨絮衍生多孔碳(DPCC)，并研究了其对染料的吸附性能及动力学性能。通过单因素实验优化工艺参数，确定最佳预处理条件(液固比为17 mL·g^-1、200 ℃处理2 h)，在此条件下制备的DPCC-10比表面积达到518 m²·g^-1。结合傅里叶变换红外光谱(FTIR)、X射线衍射(XRD)、拉曼(Raman)光谱、扫描电镜(SEM)和N₂吸附-脱附测试等表征手段，证实预处理过程能够有效去除木质素和半纤维素等，形成丰富的多级孔道结构。吸附实验表明，DPCC-10对亚甲蓝(MB)的最大吸附量达到385.71 mg·g^-1，优于多数报道的生物质衍生吸附剂。DPCC-10对染料的吸附过程满足准二级动力学方程，表明该吸附以化学吸附为主。经过4次吸附-脱附循环后，DPCC-10对MB的吸附容量仍保持初始值的92.01%，表明材料具有优异的可再生性能。

金属有机框架材料是一类具有高比表面积的无机-有机杂化晶态材料，传统的金属有机框架材料由于其导电性较差，在电子器件领域的应用受到限制。近期研究表明，通过引入含有特定共轭结构的配体以增强其导电性等设计策略，能够成功制备出具有较高导电性的金属有机框架材料，从而拓展了其应用范围。本文系统总结了导电金属有机框架材料的设计策略、表征方法、研究进展以及其最新应用，并详细探讨了该研究领域中存在的挑战及其未来的发展方向。

采用两步水热法制备了BiSbO₄/BiOBr复合材料，并对其微观形貌、物相结构、化学组成、光学性能、光催化性能进行测试。结果表明：由纳米棒组成的BiSbO₄成功负载到片状BiOBr表面，二者产生的异质结结构不仅拓宽了催化剂的光响应范围还提升了光生电子-空穴对分离效率。其在模拟可见光下的光催化性能都优于单一的BiSbO₄和BiOBr，当BiSbO₄在复合材料中的质量分数为6%时，所制备的复合材料的光催化降解亚甲蓝(MB)性能最佳，其在模拟可见光下照射120 min后对MB的降解率达91.3%，经过4次循环后降解率仍有77.4%。

Cs_xWO₃/TiO₂ composites with full‐spectrum catalytic activity were prepared by solvothermal reaction. The composites were characterized using X‐ray diffraction (XRD) analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), specific surface area testing, X‐ray photoelectron spectroscopy (XPS), and UV‐Vis diffuse reflectance spectra (UV‐Vis DRS). Cs_xWO₃ and TiO₂ were uniformly bonded together in the composites. The heterojunction structure was formed. The band gap was reduced from 2.75 to 2.65 eV. The photocatalytic property of Cs_xWO₃/TiO₂ was demonstrated by the degradation rates of 20 mg·L^-1 methylene blue dye, which were 99.7%, 91.4%, and 70.7% under irradiation from a 300 W high‐pressure mercury lamp, a 500 W xenon lamp, and a 400 W infrared lamp, respectively. After five cycles of photocatalytic degradation, the composite photocatalyst still showed a degradation efficiency of 87.6%. This indicates that Cs_xWO₃/TiO₂ has good photocatalytic degradability and cyclic stability. The photocatalytic mechanism of Cs_xWO₃/TiO₂ was investigated. The trapping experiments of the active species showed that the main active substances were the empty hole (h⁺) and hydroxyl radical (·OH).
