“…2(e) shows the high-resolution C 1s spectrum of these obtained samples. Apart from the three characteristic peaks at 284.6, 285.8, and 288.3 eV arising from the adventitious carbon [35], a newborn peak signal of C-Bi bond appeared at 282.5 eV both in C/BOC and C/BOC/B, indicating the successful incorporation of C dopants into BiOCl lattices to form C-Bi bonds [36]. By comparing the XRD spectra of C/BOC/B with other control groups, three obvious signals at 27.2 o , 37.9 o , and 39.6 o began to emerge, which belong to (012), (104), and (110) diffraction planes of elementary Bi (JCPDS no.…”

“…The understanding of the involved radicals aid towards prediction of charge transfer mechanism in a Z-scheme heterojunction [44] . Since the most common initiators of photocatalytic redox reactions stems from h + , hydroxyl radicals and superoxide anion radicals, radical scavengers for each one of them include TEOA, EDTA and ammonium oxalate (AO) for h + [46] , [47] , tert-butyl alcohol (TBA) and isopropanol (IPA) for OH radicals [48] , [49] , and N 2 gas and p-benzoquinone (BQ) as superoxide anion radical quenchers [46] , [50] . In our previous work, we managed to induce a Z-scheme charge transfer mechanism between CO 3 O 4 and BiOI towards direct Z-scheme charge transfer using just radical trapping tests and some theoretical investigations that included electronic properties of the materials [43] .…”

“…20,21 Thus, CQDs have been extensively used in the decoration of semiconductor materials to improve their photovoltaic properties leading to enhanced photocatalytic performance. 22,23 Moreover, the presence of CQDs speeds up the separation of photogenerated electron–hole pairs, promoting the use of more reactive species of holes and ·O 2 − in the photocatalytic system. 24,25 Due to the excellent merits, recently, a series of CQDs-based binary or ternary composites with efficient photocatalytic performance have been developed, such as CQDs/Bi 3 O 4 Br, 21 CQDs/BiOCl/CEM, 24 CdS/CQDs/g-C 3 N 4 , 26 CQDs/TiO 2 , 27 TiO 2 /WO 3 /CQDs, 28 etc .…”
