摘要： A photoelectrode includes a double-layer homojunction of metal oxide semiconductor films without heteroatoms incorporated. The metal oxide semiconductor films are uniform in large size with rich oxygen vacancies. For BiVO4 films, Bi precursor can be electrodeposited on a substrate under atmospheric pressure and air atmosphere. The electrolytes for electrodeposition are acidic or alkaline with controllable pHs. The electrodeposited substrate is transferred to the muffle furnace for thermal evaporation with V precursor. Film thickness and size can be controlled by electrodeposition parameters. The BiVO4 double-layer homojunction is a safer and cheaper material in photo-driven devices, hydrogen producers, and solar cells, and is an economical replacement of costly III-V compounds, polymers, and valuable fossil. The BiVO4 double-layer homojunction can also be employed as photoelectrodes for H2 production via photoelectrochemical (PEC) water splitting under solar light, which can provide pivotal reactor materials for hydrogen producers and solar cells.

摘要： A rapid method of synthesizing nanoflowers made of nanoflakes of nickel molybdate (NiMoO4) directly on nickel foam (NF) through an aerosol-assisted chemical vapor deposition (AACVD) process is disclosed. The nickel molybdate nanoflowers were grown on NF by varying the deposition time for 60 and 120 min at a fixed temperature of 480° C. and their efficiency was investigated as oxygen evolution reaction (OER) catalysts in 1 M KOH electrolyte. The NiMoO4 nanoflowers of NF obtained after 60 minutes of AACVD process showed OER performance with lowest overpotential of 320 mV to reach standard current density of 10 mA cm−2. The catalyst continuously performed the OER for 15 h, signifying its prominent stability under electrochemical conditions.
