赤铁矿光电极改性策略的研究

Research on Performance Strategy of Modified Hematite Photoelectrode

选择合适的光电极材料是提升光电催化分解水的性能的最重要因素。但是对许多用于分解水的薄膜电极而言,解决光吸收和电荷收集之间的权衡问题一直以来都存在挑战。赤铁矿作为一种窄带隙的单金属氧化材料,可以有效转换太阳能。通过探索诸多改性策略,赤铁矿光阳极材料为光电催化领域带来许多新的希望。

Choosing the right photoelectrode material was the most important factor in improving the performance of photocatalytic water splitting.But for many thin-film electrodes used to water splitting,solving the trade-off between light absorption and charge collection was always been a challenge.As a narrow band gap single metal oxide material,hematite could effectively convert solar energy.By exploring many modification strategies,hematite photoanode materials had brought many new hopes to the field of photocatalysis.
