利用水热法成功地合成了具有标准六棱柱形状的碳掺杂氧化锌纳米棒。为了通过调整表面来改变它们的光催化活性，在氨气氛下使用后蚀刻工艺，并且这些纳米棒可以转化为六边形多孔纳米棒（在750° C下），以及具有由交替的（11 2 <$1）和（11 2 <$1 <$）平面覆盖的波纹表面结构的多孔纳米棒（在850° C和950° C下）。利用能量色散谱和拉曼谱研究了掺杂碳物种的浓度和振动模式。它明确地表明，在750° C左右存在碳酸化过程，并且一些有机醛分子转化为片状形式的碳。通过对它们的光致发光谱和光催化活性的研究，我们发现合适的刻蚀温度是获得高光催化性能的关键。
Using a facile hydrothermal method, we have successfully synthesized carbon doped (C-doped) ZnO nanorods with standard hexagonal column shapes. To modify their photocatalytic activities by tailoring the surfaces, a post etching process under ammonia atmosphere was used, and these nanorods could be converted into hexagonal porous nanorods (at 750° C), and porous nanorods with corrugated surface structures covered by alternant (11 2¯ 1) and (11 2¯ 1¯) planes (at 850° C and 950° C). Energy Dispersion Spectrum and Raman spectra are used to carefully study the concentration and vibration modes of the doped carbon species. It explicitly shows that there is a carbonation process around 750° C and some organic aldehyde molecules transform into carbon with flake form. After investigating their photoluminescence spectra and photocatalytic activities, we conclude that an appropriate etching temperature is the key point to obtain high photocatalytic performance.
