A nearly complete decomposition of MO, TC and OFX over a direct Z-scheme p-n heterojunction g-C3N4/La-Bi2O3 composite

A 1D/2D Bi2O3/g-C3N4 step-scheme photocatalyst to activate peroxymonosulfate for the removal of tetracycline hydrochloride: insight into the mechanism, reactive sites, degradation pathway and ecotoxicity

“…The peak at 808 cm À1 was the characteristic peak of the s-triazine ring of g-C 3 N 4 , and the wide absorption band at 1610-1700 cm À1 was attributed to the C-N and CQN stretching vibration peaks in g-C 3 N 4 . 44 In the case of BO/CN, the characteristic absorption peaks of both Bi 2 O 3 and g-C 3 N 4 existed in the FT-IR spectrum of BO/CN, indicating the successful synthesis of the samples.…”

“…4b shows the C1s high resolution spectra of g-C 3 N 4 and BO/CN-8, and the two peaks at 284.6 and 287.8 eV are characteristic of the sp 2 CQC bonds in the aromatic ring and the sp 2 hybridized carbon of C-NQC, respectively. 44 The N1s spectrum of g-C 3 N 4 and BO/ CN-8 is depicted in Fig. 4c, the peak at 398.4eV corresponds to the aromatic N (CQN-C) peak in the sp 2 .…”

P-doped g-C3N4 with triple calcinations for dramatic photocatalytic performance

“…As shown in g. 6 (a), the photocurrent intensity of all modi ed samples is greater than that of pure CN. When the transient current intensity is greater, the electron migration rate is faster and the photocatalytic performance is better (Lun et al 2023;Nawaz et al 2021). It can be seen from the gure that with the increase of the number of calcinations, the transient current intensity also increases, but when the number of calcinations increases to four times, it echoes the XRD spectrum.…”

Design of novel Z-scheme g-C 3 N 4 /TiO 2 /CuCo 2 O 4 heterojunctions for efficient visible light- driven photocatalyic degradation of Rhodamine B

“…Researchers are very interested in heterojunction complexes made up of two semiconductor photocatalysts because of this. A heterojunction is a junction formed by the proximity of two or more semiconductors [27]. These problems could be xed by making heterojunction structures by mixing TiO 2 with the right semiconductor materials.…”
