Example Embodiment
[0030] Example 1:
[0031] figure 1 with figure 2 BiVO prepared in Example 1 4 SEM image of microspheres, using BiVO prepared in Example 1 4 The microspheres are composed of irregular polyhedrons with uniform dispersion and larger particles.
[0032] 2mmol (0.97g) Bi(NO 3 ) 3 ·5H 2 O was added to 30mL HAc (purity 99.5%), stirred until completely dissolved, as solution A; 2mmol (0.368g) of Na 3 VO 4 Add to 5mL of deionized water, stir until completely dissolved, then add 30mL of HAc (purity 99.5%), continue to stir for 30min, as solution B; add solution B to solution A dropwise and continue to stir for 30min; The latter solution C was transferred to a 100mL reactor, and a hydrothermal reaction was carried out at 140°C for 4 hours; after the reactor was cooled to room temperature, the reaction product was centrifuged and washed with deionized water and absolute ethanol for 3 times; The obtained powder was dried in an oven at 60°C for 6 hours; the dried powder was placed in a muffle ...
