All chemicals used in this study were of analytical grade and used without further purification. BiVO4 film was prepared by a modified metal-organic decomposition method with a slight modification from our previous procedure8 (link). Thus, 0.2 M Bi(NO3)·5H2O (99.8%; Kanto Chemicals) dissolved in acetic acid (99.7%; Kanto Chemicals), 0.03 M VO(acac)2 (98.0%; Sigma Aldrich) and 0.03 M MoO2(acac)2 (98.0%; Sigma Aldrich) in acetyl acetone (>99.0%; Kanto Chemicals) were prepared as a precursor solution. Then stoichiometric amount of each precursor was mixed to complete a precursor solution. For Mo doping, Bi:(V+Mo)=1:1 atomic ratio was applied for 1% Mo:BiVO4 films. For fabrication of a BiVO4 film, 60 μl of solution was dropped on a fluorine doped tin oxide (FTO) glass (2 cm × 2.5 cm) and dried for 15 min in Ar atmosphere. Depending on synthesis condition, 10–80 μl of precursor was used. The FTO glass (TEC 8; Pilkington) was cleaned by using KOH (0.1 M)+ethanol with ratio of 1:5, and washed with copious amount of deionized water and finally stored in acetone before usage. The greenish transparent precursor film was calcined at 550 °C for 25 min to form a yellow BiVO4 film. After annealing process, 2 cm × 2.5 cm BiVO4/FTO was split to obtain photoanodes with a net irradiation area of 0.24 cm2 connected by silver paste and copper wire and sealed with epoxy resin.

A solution
(25 μL) of dimethyl sulfoxide (DMSO, ≥99.5%,

(Na2MoO4, ≥99%, Sigma-Aldrich) was added
on top of the BiOI-coated substrate and dried in a preheated drying
oven at 100 °C for 60 min. Samples were calcined immediately
at 450 °C for 2 h (at a heating rate of 2 °C/min). Afterward,
the excess of vanadium(III) oxide (V2O3) was
removed by placing 500 μL of an aqueous (Milli-Q) 1 M KOH (99.99%,
Sigma-Aldrich) solution on top of the sample for 30 min, rinsing with
Milli-Q water, and drying with compressed air, and repeating this
whole procedure. Subsequently, the samples were annealed in a tube
furnace at 300 °C for 0.5 h at a heating rate of 10 °C/min
in a 5% H2/95% Ar atmosphere at a flow of 500 sccm. The
microwire-structured samples were prepared in two batches, and all
samples in each batch were processed simultaneously. The data reported
in the results paragraph are based on samples from the same batch.

at 200 °C under vacuum overnight. Toluene was dried over activated
sieves (20% by weight) for at least 24 h, then purged with nitrogen
for at least 1 h before being transferred via a cannula to a Schlenk
flask. Toluene was then pumped into the glove box overnight in an

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
