2023, Journal of Photochemistry and Photobiology A: ChemistryCitation Excerpt :The theoretical current density of hematite is 12.6 mA cm−2, but the reported photocurrent density of the α-Fe2O3 photoanode is much lower than this value. This is due to the low conductivity of hematite [4–6], low absorption coefficient [7], severe electron-hole recombination [8] and short survival time of photogenerated carriers [9,10], which limit its PEC performance. At present, the PEC properties of hematite are improved through element doping, surface modification, morphology control and construction of heterojunctions [11–13].
Recent trends in development of hematite (α-Fe<inf>2</inf>O<inf>3</inf>) as an efficient photoanode for enhancement of photoelectrochemical hydrogen production by solar water splitting
2021, International Journal of Hydrogen EnergyCitation Excerpt :As evident from its bandgap value, the wavelengths of light longer than 400 nm can be absorbed and its theoretical water splitting efficiency is about 13% [64,65]. However, the so far obtained efficiency is far below this theoretical limit commonly due to several intrinsic properties which include poor absorption [66,67], low conductivity (~10−2 cm2 V−1 s−1) [68–70], high recombination rate of electron-hole pairs due to short hole diffusion length (~2–4 nm) [71,72] and slow reaction kinetics [32,73]. Here, we highlight the current progress in the application of nanostructured α-Fe2O3 as photoanodes for PEC.
