请各位高手帮帮看看下面的中文翻译成英文，帮忙改正啊！ 不甚感激，谢谢各位! 图8为太阳光下样品对亚甲基蓝的光催化降解效果图。从图8可以看出，当太阳光照射仅20 min时，亚甲基蓝降解率X高达87.86 %，表明Sb2S3在太阳光下对亚甲基蓝有较高的光催化降解效率，表现出较高的可见光催化活性。由样品的紫外可见光谱图得到Sb2S3的吸收峰值在725~800 nm左右，落在可见光范围内，同时能带间隙1.52 eV，故太阳光照射时，它利用太阳光中的可见光进行激发，从而有效地光催化降解亚甲基蓝。 Fig.8 indicates the effect drawing of photocatalytic degradation rate of methylene blue under sunlight. From Fig. 8, it can be seen that the degradation rate of methylene blue is up to 87.86% when it is irradiated only 20 min by sunlight. It show that Sb2S3 have high photocatalytic degradation rate for methylene blue under sunlight, and demonstrate obvious visible-light activity. From the corresponding UV-visible absorption spectrum of the Sb2S3, we know that a remarkable absorption peak at the wavelength of 725~800 nm within visible light and the band gap is 1.52 eV. Thus, it can make full use of the visible light to excitated, and effectively photocatalysis degradation of methylene blue. |

The degradation rate of methylene blue was up to 87.86% after irradiated only 20 min by sunlight which indicated that the Sb2S3 had high photocatalytic catalysis degradation efficiency for methylene blue under sunlight and obvious visible-light activity. The main absorption peak of the Sb2S3 according to the corresponding UV-visible absorption spectrum is at the wavelength of 725~800 nm which is within the visible light and with the band gap of 1.52 eV. Thus, it could be excitated by the visible light of the sunlight and catalyse the photocatalysis degradation of methylene blue effectively. |

As Fig. 8 shows, degradation rate of methylene blue reaches 87.86% when it is irradiated only 20 min. It shows that Sb2S3 under sunlight have high photocatalytic degradation efficiency to methylene blue, and demonstrates obvious visible-light activity. From UV-visible absorption spectrum of sample, a remarkable absorption peak of Sb2S3 is at wavelength of 725~800 nm within visible light and the band gap is 1.52 eV. Thus, it can make full use of the visible light to excite reaction. Effectively photocatalysis degradation of methylene blue can be obtained. |
