· CaPtO3

CaPtO3 (calcium platinate) is an oxide semiconductor compound combining alkaline-earth calcium with platinum, forming a perovskite-like structure. This is a research-phase material studied primarily in electrochemistry and photocatalysis contexts rather than an established commercial material. Its potential applications leverage platinum's catalytic properties combined with oxide semiconductor characteristics, making it of interest for energy conversion, water splitting, and advanced catalytic systems where cost-effective platinum utilization is valuable.
