Cobalt Phosphate Group Modified Hematite Nanorod Array as Photoanode for Efficient Solar Water Splitting

“…However the reported efficiencies of hematite are relatively lower than theoretically predicted value of 12.4%, mainly because of the extremely short photogenerated charge carriers' lifetime and diffusion length, chemically inert oxygen evolution reaction, and low flat band potential [7][8][9]. Various approaches, i.e., manipulating nanostructure [5,10,11], chemical composition doping [8,9,[12][13][14], and surface modification [7,15] have been adopted to enhance the photoelectrochemical efficiency of ␣-Fe 2 O 3 .…”

Construct Fe2+ species and Au particles for significantly enhanced photoelectrochemical performance of α-Fe2O3 by ion implantation

“…, respectively [40]. The Fe 2p 3/2 satellite peaks located at about 719 eV are also attributed to the Fe 3+ specie [41]. More importantly, the satellite peaks located at 716 eV, which can be attributed to Fe 2+ species [21], were found in Au-Fe 2 O 3 -550 and Au-Fe 2 O 3 -700 samples, but not in pristine Fe 2 O 3 .…”

Abnormal Cathodic Photocurrent Generated on an n‐Type FeOOH Nanorod‐Array Photoelectrode

“…[26][27][28] As atellite peak of the Fe 2p 3/2 main line was observed forb oth samples at approximately 719.1 eV,w hich was most likely associated with the presence of Fe 3 + species. [29] In contrast, there was no evidencet os upport the presence of Fe 2 + in either sample, which should give rise to as atellite peak located at 717 eV. [30] Three peaks at 529.7, 531.1, and 532.7 eV were observed in the O1 sh igh-resolution XPS spectrum of the sample before calcination (Fig- Chem.E ur.J.2016, 22,4802 -4808 www.chemeurj.org ure 3b).…”
