Herein, present paper we have successfully demonstrated a facile hydrothermal synthesis of Sn₃O₄ nanowires for efficient hydrogen production under solar light irradiation. The triclinic phase and chemical composition were accomplished by XRD and XPS respectively. The morphological characterization using FESEM revealed nanowire-like morphology of the as-synthesized material. The optical band gap for Sn₃O₄ nanowires was found to be 2.55 eV. In view of the band structure in the visible region, the photocatalytic activity of the as-synthesized Sn₃O₄ photocatalyst for the hydrogen production via. H₂S splitting under natural sunlight has been investigated. The Sn₃O₄ nanowires demonstrated excellent photocatalytic activity (3933.$65\mathrm{\mu }\mathrm{m}$ol/0.5g/h) for hydrogen production. Improved photocatalytic activity was attributed to the morphology and crystallinity of as-synthesized Sn₃O₄ nanowires. Based on results obtained possible mechanism for the photocatalytic hydrogen evolution was illustrated.

在本文中，我们成功地证明了在太阳光照射下水热合成Sn ₃ O ₄纳米线的简便方法，可以有效地制氢。三斜晶相和化学组成分别通过XRD和XPS完成。使用FESEM进行的形态表征揭示了所合成材料的纳米线状形态。发现Sn ₃ O ₄纳米线的光学带隙为2.55eV。考虑到可见区域中的能带结构，所合成的Sn ₃ O ₄光催化剂对氢气产生通孔的光催化活性。已经研究了在自然阳光下H ₂ S的分解。锡₃ O ₄纳米线表现出出色的光催化活性（3933。$\mathrm{65岁}\mathrm{\mu }\mathrm{米}$ol / 0.5g / h）制氢。改善的光催化活性归因于合成后的Sn ₃ O ₄纳米线的形态和结晶度。根据获得的结果，阐明了光催化氢释放的可能机理。
