Unraveling the role of Ti3C2 MXene underlayer for enhanced photoelectrochemical water oxidation of hematite photoanodes

Haiyan Ji et al.

Summary: The study presented a Ti3C2 MXene underlayer modified hematite photoanode, which significantly enhanced the PEC performance of hematite and increased the photocurrent density. Furthermore, subsequent surface F-treatment and the loading of FeNiOOH cocatalyst further improved the PEC performance, leading to a dramatically increased photocurrent density and a lowered onset potential.

Heterojunction of nanostructured α-Fe2O3/CuO for enhancement of photoelectrochemical water splitting

Pannan Kyesmen et al.

Summary: This research focused on preparing nanostructured heterojunction of alpha-Fe2O3 and porous CuO composites as photoanodes for PEC water splitting. The formations of heterojunction and porous surface morphology facilitated charge separation and enhanced PEC efficiency. The reduced bandgap and increased photon absorption in the visible spectrum were key factors in improving photocurrent density.

One-step in-situ formation of TiO2 nanosheets interconnected hematite photoanode for enhanced water oxidation

Xiaoxin Lv et al.

Summary: In this study, a Ti3C2 MXene derived TiO2 nanosheets/hematite photoanode with interconnected structures was fabricated via a facile method. Compared to the pristine Fe2O3 film, the Fe2O3/TiO2 photoanode showed increased photocurrent density and improved performance after loading FeNiOOH cocatalyst. These improvements were attributed to facilitated charge separation and transport, accelerated OER kinetics, and the formation of interconnected structures.

Yong Peng et al.

Summary: The nanoporous titanium-doped alpha-Fe2O3 thin films fabricated using a hydrothermal reaction and energetic plasma ion implantation exhibit significantly enhanced photoelectrochemical water oxidation performance, with approximately 1.6-fold increases in photocurrent compared to pristine Fe2O3, attributed to improved charge carrier transport induced by Ti doping. This work provides new insights into surface engineering of photo-responsive semiconductors for emerging hydrogen technologies.

Wasted photons: photogeneration yield and charge carrier collection efficiency of hematite photoanodes for photoelectrochemical water splitting

Yifat Piekner et al.

Summary: Hematite is a promising material for photoelectrochemical water splitting, but the champion hematite photoanodes have achieved less than half of their predicted maximal photocurrent due to unproductive optical excitations. A comprehensive method for extraction of photogeneration yield spectrum reveals that the photogeneration yield of a thin film hematite photoanode is less than unity, limiting its maximal photocurrent potential.
