Prominent co-catalytic effect of CoP nanoparticles anchored on high-crystalline g-C3N4 nanosheets for enhanced visible-light photocatalytic degradation of tetracycline in wastewater
Abstract
Abstract Graphitic carbon nitride (g-C3N4) has been regarded as an emerging and promising semiconductor photocatalyst for the solar hydrogen production and organic pollution removal. However, pure g-C3N4 typically exhibits moderate photocatalytic activity. And the amorphous structures and the rapid recombination of the electron-hole pairs are the two main challenges for the improved photocatalytic performance of the single bulk g-C3N4. In this work, we reported the CoP as a co-catalyst modified high-crystalline g-C3N4 (HCCN) to form an stable and highly efficient CoP/HCCN composite via a simple solvothermal method. As expected, the as-prepared composites showed impressive photocatalytic performance toward the tetracycline (TC) degradation. In particular, 5 wt% CoP/HCCN exhibited the optimum photocatalytic efficiency (96.7%, 120 min) and its corresponding degradation rate constant is 10.2 times than HCCN. Additionally, the role of coexisting ions in simulated practical TC wastewater was explored. The enhanced photocatalytic performance mainly derives from two factors: (i) the formation of HCCN to reduce structural defects; (ii) CoP as the cocatalyst on the HCCN surface to accelerate the separation of the photo-generated electrons-hole pairs and strengthen the surface photoreaction of the samples. Our work opens up a new window to the construction of highly effective HCCN-based composite photocatalysts for solar light-driven wastewater treatment.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
