Enhanced photoelectrochemical water splitting performance of α-Fe2O3 nanostructures modified with Sb2S3 and cobalt phosphate

3D Branched Ca‐Fe2O3/Fe2O3 Decorated with Pt and Co‐Pi: Improved Charge‐Separation Dynamics and Photoelectrochemical Performance

“…3a,asignificant increase in absorption for all samples is observed at wavelengths below 600 nm, corresponding to a bandgapo fa pproximately 2.1-2.2 eV,w hich is closet ot he values in the previous report [25]. Compared with Fe 2 O 3 NRs, 3D BNRs of Fe 2 O 3 indicate ah igherl ight-absorption intensity, which mightb ea ttributed to interference by the small branch-…”

Rational Design and Construction of Cocatalysts for Semiconductor‐Based Photo‐Electrochemical Oxygen Evolution: A Comprehensive Review

“…In order to further optimize the PEC performance of catalysts, some ternary composites containing Co–Pi like Fe 2 O 3 /CdS/Co–Pi and BiVO 4 /ZnO/Co–Pi are also proposed . These ternary catalysts exhibit much more prominent water oxidation capability due to the intimate contact of three composites and the synergistic effects among them.…”

Design of Hydrothermally Derived Fe2O3 Rods with Enhanced Dual Functionality Via Sputtering Decoration of a Thin ZnO Coverage Layer

“…A flat band potential of approximately −0.55 V (versus Ag/AgCl) was determined from the intercept on the X axis for the F-1 and F-2, while for the F-1-Z and F-2-Z, the flat band exhibits a negative shift of approximately 20 mV, indicating that a quasi-Fermi level of the Fe 2 O 3 −ZnO band bends upward due to the decoration of ZnO crystals. 37 All of the slopes of the M-S curves Furthermore, the slopes of tangent lines for M-S plots of the F-1-Z and F-2-Z composite rods were 6.6 × 10 −2 and 5.5 × 10 −2 , respectively. The smaller linear fitting slope of the F-2-Z suggested its higher charge carrier concentration and photoactivity compared with F-1-Z.…”
