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。
