要旨

To develop environmentally friendly and cost-effective wastewater treatment technologies, in this study, a photo-Fenton heterogeneous catalyst Mn–FeOOH/gC3N4 with a three-dimensional porous tubular structure is prepared using a simple chemical precipitation method. Due to the loading of Mn–FeOOH, the shortcomings of graphite phased carbon nitride (g-C3N4) with rapid photogenerated carrier recombination and low specific surface area are improved. Meanwhile, the synergistic effect of Mn and Fe can promote the activation of hydrogen peroxide. In addition, the three-dimensional tubular structure can promote the absorption and refraction of visible light. Consequently, Mn–FeOOH/gC3N4 composites acquire a degradation efficiency of 97.7% at 30 min in a photo-Fenton system. The reaction rate K of Mn–FeOOH/gC3N4 is 0.11689 min−1, which is 24.6 times that of gC3N4 (0.00476 min−1). In summary, this study offers an innovative strategy for constructing 3D heterogeneous photo-Fenton composite catalysts.

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
