We show that highly oxidizing valence band holes, produced by ultraviolet (UV) illumination of naturally occurring semiconducting minerals, are capable of oxidizing chloride ion to perchlorate in aqueous solutions at higher rates than other known natural perchlorate production processes. Our results support an alternative to atmospheric reactions leading to the formation of high concentrations of perchlorate on Mars.
我们证明了，在自然存在的半导体矿物的紫外（UV）光照下产生的高氧化性价带空穴，能够以比其他已知的天然高氯酸盐生成过程更高的速率将氯离子氧化为高氯酸盐。我们的结果支持了一种替代大气反应的方案，该方案导致火星上高浓度高氯酸盐的形成。
