Cu(II) harmonize g-C3N4 and black phosphorous together under the interaction of surface charges to form unconventional type-II photocatalyst BPs/Cu/CNs with attractive performance

In situ growth of an ultrathin Cu/g-C3N4 coating over SBA-15 for catalytic wet air oxidation of pollutants under extremely mild conditions

“…These results are in a good agreement with those reported in the literature. 59 The peak at 284.5 eV in C 1s belongs to C–C, while the peak at 285.8 eV belongs to the sp 2 hybrid carbons in CN–C, further proving the presence of g-C 3 N 4 over SBA-15. 62…”

“…58 The O 1s XPS peaks of Cu 1 /CN 3.3 @SBA-N can be fitted to three peaks at 532.1 eV, 533.2 eV and 535.1 eV, corresponding to lattice oxygen (O–metal), chemisorbed oxygen or hydroxyl groups (Si–O/OH), and adsorbed water (O–H 2 O), respectively. 17,59 The lattice oxygen content over Cu 1 /CN 3.3 @SBA-N is significantly higher than that of Cu 1 /CN 3.3 @SBA (Fig. S7†), which is conducive to the oxidation reaction.…”

“…These results are in a good agreement with those reported in the literature. 59 The peak at 284.5 eV in C 1s belongs to C-C, while the peak at 285.8 eV belongs to the sp 2 hybrid carbons in CvN-C, further proving the presence of g-C 3 N 4 over SBA-15. 62 The bandgap energies (E g ) estimated by the Kubelka-Munk method based on the relationship between (αhν) 2 and hν are shown in Fig.…”

Enhanced photocatalytic performance of anatase titania nanotubes via the synergistic effect of trace copper doping and oxygen vacancies

“…Given the good photocatalytic performance of Cu@ANTs towards RhB, we evaluated its adaptability to more types of pollutants. Tetracycline hydrochloride (TCH), 80 ciprofloxacin (CIP), 69 phenol, 81 and bisphenol A (BPA) 82 were selected as representatives of antibiotics, chemical products, and endocrine disruptors. The degradation results are shown in Fig.…”

The preserved S-scheme band structure of graphitic carbon nitride/bismuth oxobromide after the introduction of black phosphorus driven by an internal electric field: achieving significantly enhanced photocatalytic performance

“…Additionally, our research group has introduced a new metric ( I , mg (g −1 min −1 )) to assess the degradation capacity, representing the mass of pollutants that can be degraded by one unit mass of catalyst per minute. 49 This metric takes into account the efficiency and kinetics of the photocatalytic process, allowing us to more accurately compare the performance of the as-prepared photocatalysts with other photocatalysts published in related work. As a consequence, the as-prepared 6BPs/CNs/BOB 1:2 with the greatest photocatalytic performance in this work still demonstrates some advantages, either for the kinetic reaction rate k or the index I (1.177 mg (g −1 min −1 )) as collected in Table S2 †…”
