Ambient S annealing was adopted to regulate the crystallinity of a ZnS microsphere, which resulted in a significant improvement in the photocatalytic hydrogen production activity (PHPA). Moreover, with S ambient treatment, wurtzite ZnS showed better PHPA than sphalerite ZnS, possibly because the inter-polar electric field of the wurtzite phase could promote the separation of photo-excited electron-hole pairs.
采用环境 S 退火来调节 ZnS 微球的结晶度,这使得光催化制氢活性(PHPA)得到显著提高。此外,在 S 环境处理下,纤锌矿型 ZnS 表现出比闪锌矿型 ZnS 更好的 PHPA,这可能是因为纤锌矿相的内极电场可以促进光激发电子-空穴对的分离。
