A total of 5 g urea (NH₂CONH₂, NIHON SHIYAKU REAGENT) was added into an aluminum crucible, and subsequent thermal treatment at 550 °C for 2 h with 5 °C min⁻¹ of heating rate in argon atmosphere could obtain a light-yellow powder composed of g-C₃N₄ nanoparticles. A total of 3.38 g bismuth (III) nitrate pentahydrate (Bi(NO₃)₃·5H₂O, Alfa Aesar) was placed in 40 mL of 2 M nitric acid solution (solution A). Then, 0-40 wt% g-C₃N₄ was put into solution A to be stirred for 1 h. The 0.81 g ammonium metavanadate (NH₄VO₃, Acros) was dissolved in 40 mL of deionized (DI) water (solution B). The 1 wt% surfactant, such as citric acid monohydrate (CIT, C₆H₈O₇•H₂O, fw: 192.12, SHOWA), (1-hexadecyl)trimethylammonium bromide (CTAB, CH₃(CH₂)₁₅N(CH₃)₃Br, fw: 364.42, Alfa Aesar), and polyethylene glycol (PEG, C_2nH_4n+2O_n+1, fw: 4,000, SHOWA), was added into the solution B. The 0-20 mol% copper (II) acetate monohydrate (Cu(CH₃COO)₂•H₂O, Merck) was also added in 20 mL of DI water (solution C). Subsequently, solution A and solution C were added into solution B. Then, the reaction mixture was treated with a sonochemical instrument (700 W, 20 kHz, Q700 SONICATOR) for 0.5 h–2 h at 60 °C [4 (link)]. Finally, the copper-doped BiVO₄/g-C₃N₄ samples were collected.

Spray Pyrolysis of BiVO4 Thin Films

Check if the same lab product or an alternative is used in the 5 most similar protocols

Thin films of BiVO₄ were deposited by spray pyrolysis. Bi(NO₃)₃·5H₂O (98%, Alfa Aesar) and VO(AcAc) (99%, Alfa Aesar) were dissolved in acetic acid (98%, Sigma Aldrich) and absolute ethanol (Sigma Aldrich), respectively. The Bi solution was then added to the V solution (Bi : V = 1 : 1), and the mixture was diluted to 4 mM with excess ethanol. The acetic acid to ethanol volume ratio in the final solution is 1 : 9. The final solution was then ultrasonicated for 15 minutes. The FTO substrate was heated to 450 °C during deposition. The precursor solution was sprayed in a pulsed deposition mode onto the FTO, with one spray cycle consisting of 5 s spray time followed by 55 s delay time to allow the solvent to evaporate. After deposition, the films were annealed for 2 hours at 450 °C in air. More details can be found in previous reports.^{24 ,25 (link)}

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.
