摘要

本文研究了卤素掺杂的二氧化锡（SnO2）的光催化活性以及除光伏设备外的其他应用。虽然二氧化锡在能源设备方面得到了广泛的研究，但对其作为光催化剂的研究关注度并不高。对光催化特性的初步研究表明，Br:SnO2 在最初 14 小时内的氢气产生量略有提高，而一般情况下，任何卤素的存在都会降低 SnO2 的反应活性。将这一结果与观察到的电导率增加相结合，可以认为掺杂 Cl 和 Br 是增强二氧化锡层电子传输特性的有效方法。

Halogen-doped SnO2 for hydrogen production: A theoretical and experimental investigation

Halogen-doped tin dioxide (SnO2) is examined for its photocatalytic activity and further applications apart from the photovoltaic devices. While SnO2 has been extensively examined in energy devices, not so much attention has been paid to its investigation as a photocatalyst. Preliminary studies on photocatalytic properties suggest that Br:SnO2 shows a small improvement in hydrogen production in the first 14 h, whereas, in general, the presence of any halogen reduces the reactivity of SnO2. By incorporating this result with the observed increase in conductance, it can be suggested that the doping of Cl and Br serves as an effective method for enhancing the electron-transport properties of SnO2 layers.
