Hematite (iron oxide) is a promising electrode material for photoelectrochemical hydrogen generation from water. It has low cost, good long-term stability and absorbs light efficiently. However, its use is limited by its poor electrical conductivity. This project aims to develop a novel host-guest nanostructure that exploits the beneficial light-absorption properties of hematite (the guest) but shifts the charge transport function to a nanostructured transparent conductive oxide host. The project aims to produce nanostructured hematite electrodes for efficient hydrogen production from water and sunlight, thus making a significant contribution to the goal of commercially-viable storage of solar energy in the form of hydrogen.

赤铁矿（氧化铁）是一种很有前途的光电化学水制氢电极材料。具有成本低、长期稳定性好、吸光效率高等特点。然而，它的使用受到其导电性差的限制。本项目旨在开发一种新的主-客体纳米结构，利用赤铁矿（客体）有益的光吸收特性，但将电荷传输功能转移到纳米结构的透明导电氧化物主体上。该项目旨在生产纳米结构的赤铁矿电极，用于从水和阳光中高效地生产氢气，从而为实现以氢气形式储存太阳能的商业可行目标做出重大贡献。
