Hot to trot! The plasmon resonance effect of metal nanoparticles (NPs) offers a promising route to improve the solar energy conversion efficiency of semiconductors. Hot electrons generated by the plasmon resonance effect of gold NPs, however, inject into the surface states, instead of the conduction band of Fe₂O₃ photoanodes, so surface recombination occurs. The surface of Fe₂O₃ can be passivated through modifying inert oxides before loading gold NPs for plasmon-enhanced photoelectrochemical water splitting.

界面操作可改善等离子耦合光电化学水在α-Fe2O3光电阳极上的分裂

热到小跑！金属纳米粒子（NPs）的等离振子共振效应为提高半导体的太阳能转换效率提供了一种有希望的途径。但是，由金NP的等离子体共振效应产生的热电子注入到表面态，而不是Fe ₂ O ₃光电阳极的导带，因此发生了表面重组。Fe ₂ O ₃的表面可在添加金纳米颗粒用于等离子体增强光电化学水分解之前，通过改性惰性氧化物进行钝化。
