(GO/TiO₂)_N (GO represents graphene oxide, and N represents the period number of alternate superposition of two dielectrics) one-dimensional photonic crystal with different lattice constants was prepared via the sol-gel technique, and its transmission characteristics for photocatalysis were tested. The results show that the lattice constant, filling ratio, number of periodic layers, and incident angle had effects on the band gap. When the lattice constant, filling ratio, number of periodic layers, and incident angle were set to 125 nm, 0.45, 21, and 0°, respectively, a gap width of 53 nm appeared at the central wavelength (322 nm). The absorption peak of the photocatalyst at 357 nm overlapped the blue edge of the photonic band gap. A slow photon effect region above 96% reflectivity appeared. The degradation rate of tetracycline in (GO/TiO₂)_N photonic crystal was enhanced to 64% within 60 min. Meanwhile, the degradation efficiency of (GO/TiO₂)_N one-dimensional photonic crystal was effectively improved compared with those of the GO/TiO₂ composite film and GO/TiO₂ powder.

（GO / TiO ₂）_N（GO表示氧化石墨烯，N代表两个介电体交替叠加的周期数）通过溶胶-凝胶技术制备了具有不同晶格常数的一维光子晶体，并测试了其光催化传输特性。结果表明，晶格常数，填充率，周期性层数和入射角对带隙有影响。当晶格常数，填充率，周期性层数和入射角分别设为125nm，0.45、21和0°时，在中心波长（322nm）处出现53nm的间隙宽度。光催化剂在357 nm处的吸收峰与光子带隙的蓝色边缘重叠。出现了反射率高于96％的缓慢光子效应区域。四环素在（GO / TiO ₂）_N中的降解速率光子晶体在60分钟内增强到64％。同时，与GO / TiO ₂复合膜和GO / TiO ₂粉末相比，有效提高了（GO / TiO ₂）_N一维光子晶体的降解效率。
