· Sb5IO7

Sb₅IO₇ is an antimony iodine oxide semiconductor compound combining group 15 and halogen elements in a mixed-valence structure. This is a research-phase material primarily investigated for photocatalytic and optoelectronic applications, particularly in contexts where bismuth-free alternatives to traditional semiconductors are desirable. The material belongs to an emerging class of layered halide compounds being explored for visible-light photocatalysis, water treatment, and potentially thin-film electronic devices.
