“…However, the electrostatic attraction force between the negatively charged RhB and the positively charged Er 6% Mn 2% /BiVO 4 can promote the accumulation of RhB on the surface of the photocatalyst. 44 This demonstrates that the electrostatic force plays a vital factor in the photocatalytic activity of Er 6% Mn 2% /BiVO 4 on the degradation of RhB. Finally, Er 6% Mn 2% /BiVO 4 was observed to exhibit the best photocatalytic activity under optimal conditions of (a) a photocatalyst concentration of 2.0 g L −1 , (b) a solution with pH 2, and (c) an irradiation time of 60 min.…”

“…10 The h + located at the VB edge of Er 6% Mn 2% /BiVO 4 cannot oxidize the adsorbed H 2 O to produce ·OH because the VB edge of Er 6% Mn 2% /BiVO 4 (2.02 eV) is more negative than the standard redox potential of ·OH/H 2 O (2.80 eV vs. NHE). 11,44 The photogenerated holes on the VB of Er 6% Mn 2% /BiVO 4 possesses strong oxidation capacity and can participate directly in the photocatalytic degradation of RhB. 44 The ·O 2 − and h + active species generated in Er 6% Mn 2% /BiVO 4 participate in the redox reaction of RhB under visible light, ultimately resulting in its photocatalytic degradation of RhB (eqn (8) and (9)).…”

“…Bare 2D BiVO 4 exhibited a visible-light absorption range below 510 nm because of the transition of electrons from Bi 6s to V 3d corresponding to visible light. 44,45 After the BTO was coupled with BVO, the absorption edges of the BTO/BVO heterostructure showed a slight red-shift with the decreasing content of BTO, resulting from the absorption capacity of visible-light contributed by BiVO 4 . As presented in Fig.…”

“…Este comportamento foi esperado devido ao fato de haver uma menor concentração de íons H + que facilita a concentração livre de íons BiO + e V O − 3 , responsáveis pela formação das partículas de BiV O 4 , melhorando o processo de cristalização . Além de apresentar uma taxa de nucleação mais rápida, um pH mais alto produz partículas maiores (54,99). Não há variação significativa na espessura das amostras.…”
