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).

以废旧棉织物为原料，氯化锌为活化剂，采用一步活化-炭化法制备具有丰富孔隙结构的废旧棉织物基炭吸波材料(CCF)，并探讨了不同氯化锌质量分数对CCF吸波性能的影响。结果表明：氯化锌能够有效丰富CCF的孔隙结构，提高其吸波效果。在炭化温度为700 ℃(N₂气氛下)、氯化锌质量分数为10%时制备的CCF-10的比表面积高达1 310 m²·g^-1，其在厚度为2.0mm时的最小反射损耗达-35.02 dB，有效吸收带宽为5.6 GHz。
