Amorphous type FeOOH modified defective BiVO4 photoanodes for photoelectrochemical water oxidation

Boosting alkaline water splitting and the urea electrolysis kinetic process of a Co3O4 nanosheet by electronic structure modulation of F, P co-doping

“…After Se doping, the d-band center of F-Se-Co 3 O 4 is further closer to the Fermi level. [54][55][56] According to the d-band center theory, when the d-band center is close to the Fermi level, the generated antibonding orbital energy will be higher than the Fermi level after its interaction with the intermediate, 57 which means that the active center has a stronger adsorption on the intermediate. In other words, there is a stronger interaction between F-Se-Co 3 O 4 and the adsorbate, while the interaction between F-P-Co 3 O 4 and the adsorbate is relatively weak.…”

Bifacial Modulation of Carrier Transport in BiVO4 Photoanode for Stable Photoelectrochemical Water Splitting via Interface Engineering

“…The applied bias photon to current conversion efficiency (ABPE) of the electrochemical system was measured in the 0.5 m Na 2 SO 4 electrolyte in the absence of sacrificial reagent and using the following relationship: [39,40] ABPE % mA cm 1.23 mW cm 100…”

Self-driven dual hydrogen production system based on a bifunctional single-atomic Rh catalyst

“…Thus, the theoretical electromotive force ( E emf = E c − E a ) of the battery can be confirmed as 1.32 V. However, it is hard for the voltage to drive the OWS due to the sluggish kinetics and high theoretical thermodynamic potential of the anodic OER of 1.23 V versus the reversible hydrogen electrode ( vs. RHE). 17–20 Fortunately, replacing the OER with the HzOR and forming an OHzS system can sharply decrease the operating voltage due to its unique feature of the ultra-low theoretical oxidation potential of −0.33 V vs. RHE. 21–24 Therefore, a self-driven dual hydrogen production system can be constructed by combining a Zn–H 2 battery and OHzS, which can generate hydrogen efficiently on two cathodes (the Zn–H 2 battery and OHzS electrolytic cell) simultaneously with high energy efficiency.…”
