Recent research progress on operational stability of metal oxide/sulfide photoanodes in photoelectrochemical cells

“…2(a), taking 2.0 eV as an example, the energy provided by the semiconductor is sufficient to carry out the water decomposition reaction. At the same time, the utilization range of light can reach 620 nm, and the corresponding STH efficiency reaches 17.9% [28], which is much higher than the commercial standard. Considering it comprehensively, the optimal value of Eg should be 2.0-2.6 eV, as shown in Fig.…”

Bridging electrocatalyst and cocatalyst studies for solar hydrogen production via water splitting

“…Impregnation by drop casting the CC precursor and a subsequent mild annealing is oen applied when constructing CC/PE composites. [124][125][126] Hydrothermal method can also be employed by immersing PEs in a reaction vessel containing CC precursors (Fig. 5e).…”

Interfacial band alignment and photoelectrochemical properties of all-sputtered BiVO4/FeNiOx and BiVO4/FeMnOx p–n heterojunctions

“…12,13 Recently, iron-based bimetallic oxides have been established as low-cost and efficient cocatalysts for the oxygen evolution reaction (OER). 8,9,14,15 For instance, Wang et al synthesized BiVO 4 /FeCoO x films with an AM 1.5G photocurrent density of 4.82 mA cm À2 at +1.23 V vs. RHE and with excellent chemical stability. 8 Similarly, Zhang et al deposited FeNiO x cocatalyst onto boron-treated BiVO 4 films, achieving a high photocurrent of 5.22 mA cm À2 at +1.23 V vs. RHE.…”
