Ytic activity [39,40]. From Figure S1, the reaction rate continuous (k) of S2 (0.4661 min-1 ) is a great deal larger than that of Bi2 O2 CO3 , S1, S3 and S4 (0.0049, 0.0731, 0.1363 and 0.0594 min-1 ) in Alvelestat tosylate degrading Cr (VI), exhibiting S2 sample superior photocatalyst. The reaction price continuous (k) of S2 is also larger than that of Bi2 O2 CO3 , S1, S3 and S4 in degrading MO (20 mg/L) and BPA (20 mg/L) (Figures S2 and S3). The one of a kind 2D vertical on 1D structure endows Bi2 O2 CO3 iOI photocatalyst with distinctive photocatalytic activity. Firstly, 2D BiOI nanosheets vertically grew on the 1D Bi2 O2 CO3 nanorods which can deliver pretty much exposure entire active web pages; Secondly, 1D Bi2 O2 CO3 structures give promptly charge carriers transfer path along their axis; Moreover, the high-quality interface amongst Bi2 O2 CO3 and BiOI promotes the transfer price of photogenerated charge carriers at junction interface, enhancing photocatalytic activity.Catalysts 2021, 11,in degrading MO (20 mg/L) and BPA (20 mg/L) (Figures S2 and S3). The distinctive 2D vertical on 1D structure endows Bi2O2CO3 iOI photocatalyst with distinctive photocatalytic activity. Firstly, 2D BiOI nanosheets vertically grew on the 1D Bi2O2CO3 nanorods which can give almost exposure whole active web sites; Secondly, 1D Bi2O2CO3 structures give promptly charge carriers transfer path along their axis; Moreover, the high-quality inter6 of 12 face amongst Bi2O2CO3 and BiOI promotes the transfer rate of photo-generated charge carriers at junction interface, enhancing photocatalytic activity.3.1.a0.6 0.four 0.two 0.0 -1.0 0.eight 0.6 0.four 0.two Bi2O2CO3 S1 S2 S3 S4 -20 -b2.Absorbance(a.u.)0.two.0 1.five 1.0 0.five 0.01.C/CBi2O2CO3 S1 S2 S3 S4 -25 -20 -Light on -10 -5 0 five 10-30min 0min 2min 5min 8minTime(min)Wavelength(nm)cAbsorbance(a.u.)1.2 1.0 0.8 0.six 0.four 0.2 0.0 200 300 400 500 600dC/CLight on -10 -5 0 five 10Catalysts 2021, 11,0.0 –30min 0min 5min 8min 10min 13min7 of-Time(min)1.Wavelength(nm)0.e0.8 0.six 0.4 0.two 0.0 -30 Bi2O2CO3 S1 S2 S3 S4 -25 -20 -fAbsorbance(a.u.)0.4 0.three 0.two 0.1 0.0-30min 0min 3min 5min 8min 13minC/CLight on -10 -5 0 five 10Time(min)Wavelength(nm)Figure six.
