Herein, in order to improve the conductivity and slack water oxidation kinetics of hematite (α-Fe2O3) photoanode, we propose Nb-doped Co(OH)x cocatalyst-deposited α-Fe2O3 thin film photoanode (Nb-HT/Co(OH)x) via situ diluted hydrothermal microwave-assisted methods. The as-prepared Nb-HT/Co(OH)x thin-film exhibited a photocurrent density 1.78 mA cm–2 at 1.23 V versus reversible hydrogen electrode (RHE), which is 1.7-fold higher than that Bare-Fe2O3 photoanode. dual effect Nb-doping deposition...
Ru–FeOOH and FeNi(OH) x dual-layer cocatalysts passivated the recombination surface states, resulting in Fermi level de-pinning effect, while tailoring intermediate states for effective hole transfer to electrolyte.
The influence of CTAB and metallic Au NPs on the PEC activity a Zr-doped Fe 2 O 3 photoanode is described. surfactant assists in situ adsorption Zr-FeOOH during hydrothermal synthesis.
Hematite (α-Fe2O3)-based photoanodes offer great potential for use in solar hydrogen production as part of efforts to construct a sustainable and renewable energy economy based on photoelectrochemical (PEC) water splitting. A co-doping modification is the utmost significance improving PEC performance. To develop an efficient photoanode, comprehensive grasp co-dopants with diverse valence states necessary. Herein, we describe hydrothermal dip-coating approach fabrication Hf-doped Fe2O3...
Phenol is one of the most prevalent contaminants discovered in water bodies. The adsorption process gaining popularity as a viable method removing phenolic chemicals from contaminated aquatic resources. elimination using Palmyra kernel shell activated charcoal has been extensively investigated. removal effectiveness was calculated physically, chemically (H3PO4 and NaOH) magnetically for various amounts components varying durations. According to this research study, physically much higher...
The erratically ZrO<sub>2</sub> loaded hematite cauliflower photoanodes quenched at 650 °C showed 14 times higher PEC performance than the conventionally prepared nanorod photoanode (PQ650).
The interplay between diffusion/doping and surface passivation of TZF NCs exhibits a breakthrough photocurrent density 0.73 mA cm<sup>−2</sup> (1.23 V <italic>vs.</italic> RHE) with 98% stability over 10 h in the TZF/Al<sub>2</sub>O<sub>3</sub>/CoO<sub>x</sub> photoanode.
The development of efficient photoanodes for solar fuel generation via photoelectrochemical (PEC) water splitting is becoming a bottleneck. These limitations necessitate the design iron-containing metal oxides, like "ferrites-based electrode materials" with improved oxygen evolution kinetics, light absorptivity, and intrinsic stability, yet at low cost. Herein, we report in-situ formation Zr–ZnFe2O4/Fe2O3 heterojunction (ZZFO/HT) photoelectrodes using facile magnetron sputtering hydrothermal...
Dual elemental doping strategies have been employed for the fabrication of fluorine and zirconia co-doped hematite (F–Zr:Fe2O3/FTO) photoanodes. The F–Zr:Fe2O3/FTO photoanode has a (110)-oriented structure, remarkable photocurrent density 1.91 mA cm-2 without any catalyst supports, at water oxidation potential 1.23 VRHE. enhancement in net is attributed to synergistic effect two doping. situ doped Zr4+ ions substituted iron increase photogenerated free electrons within bulk resulting...
