Hematite – Stones of Healing

Hematite is a shiny, dark-coloured stone found all over the world. It is made mainly of iron, which gives it its metallic sheen. It also gives it an interesting quirk of naming – although the hematite that we see in our daily lives is dark grey, its name comes from a Latin phrase meaning "blood stone." Get price

Effect of Oxygen–Iron Composition on Charge Transport

Hematite is composed of iron and oxygen elements, and the iron–oxygen spatial distribution would affect directly its photoelectrochemical (PEC) performance. However, less work has focused on the effect of iron–oxygen composition on the characteristic of charge transport and interfacial reaction. Here, we investigated the charge transfer and interface reaction of two typical iron–oxygen Get price
