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）是一种有前途的电极材料，用于从水中产生光电化学氢。它具有低成本，良好的长期稳定性并有效吸收光。但是，其使用受到其不良电导率的限制。该项目旨在开发一种新型的宿主纳米结构，以利用赤铁矿的有益光吸收特性（来宾），但将电荷传输函数转移到纳米结构的透明导电氧化物宿主。该项目旨在生产纳米结构的赤铁矿电极，以从水和阳光下产生有效产生氢，从而为以氢的形式产生了可在商业上可行的太阳能存储的目标。
