“…The above results obtained indicate that, in the photocatalytic reaction process, O 2 – and h + are the main active species, with ·O 2 – playing a more important role. Here, a simple comparison of the photocatalytic degradation efficiency for MO by various Cu 2 O-based photocatalysts prepared in this work and others reported in literatures − has been made, and the results are shown in Figure d. More information about the comparison is given in Table S4.…”

Enhancing the efficiency of photocatalysts in the removal of organic pollutants is of vital importance in wastewater treatment. In this work, a set of composite membranes that can be used for efficient removal of the organic dyes, such as methyl orange (MO), methylene blue (MB), and Congo red (CR), were prepared through coblending/ electrospinning techniques using polyvinylidene fluoride (PVDF) as the substrate, polyvinylpyrrolidone (PVP) as the dispersing agent and wettability regulator, and cuprous oxide (Cu 2 O) as the photocatalyst. The results showed that Cu 2 O particles were well encapsulated in the electrospun PVDF/PVP fibers, and the composite membranes exhibited apparently enhanced hydrophilicity. Furthermore, compared with the pure Cu 2 O particles, the composite membranes not only showed a higher photocatalytic degradation ratio for MO (93.6%) but also showed a much higher degradation rate (62.4 mg/(mg•h)) in comparison with the other reported Cu 2 O-based composite photocatalytic materials in the literature. In addition, the membrane sample also had excellent recycling stability, and the retention rate of its removal ability maintained 92.1% after 5 times of recycling. Furthermore, the composite membranes also showed high removal ability toward MB and CR, with photocatalytic degradation ratios of 81.4 and 76.1%, respectively. This work indicates that the prepared PVDF/PVP-Cu 2 O composite membranes possess promising application prospects in wastewater treatment.

In this present work, the preparation of ternary MoS2–NiO–CuO nanohybrid by a facile hydrothermal process for photocatalytic and photovoltaic performance is presented. The prepared nanomaterials were confirmed by physio-chemical characterization. The nanosphere morphology was confirmed by electron microscopy techniques for the MoS2–NiO–CuO nanohybrid. The MoS2–NiO–CuO nanohybrid demonstrated enhanced crystal violet (CV) dye photodegradation which increased from 50 to 95% at 80 min; The degradation of methyl orange (MO) dye increased from 56 to 93% at 100 min under UV–visible light irradiation. The trapping experiment was carried out using different solvents for active species and the Z-Scheme photocatalytic mechanism was discussed in detail. Additionally, a batch series of stability experiments were carried out to determine the photostability of materials, and the results suggest that the MoS2–NiO–CuO nanohybrid is more stable even after four continuous cycles of photocatalytic activity. The MoS2–NiO–CuO nanohybrid delivers photoconversion efficiency (4.92%) explored efficacy is 3.8 times higher than the bare MoS2 (1.27%). The overall results indicated that the MoS2–NiO–CuO nanohybrid nanostructure could be a potential candidate to be used to improve photocatalytic performance and DSSC solar cell applications as well.

Faced with the aggravation of environmental pollution and the looming energy crisis, BiVO4, as an emerging and promising photocatalyst, has drawn more and more attention of researchers. Because of its suitable band gap and special electronic structure, BiVO4 shows excellent photocatalytic activity, which has the advantages of low preparation cost, excellent visible-light absorption, and suitable edge position. Herein, the research status of BiVO4-related catalysts used in photocatalysis was reviewed, including preparations using the hydrothermal method, metal–organic decomposition method, metal doping like noble metal and rare earth, and other structure designs of BiVO4. The modification mechanism of BiVO4 was also further discussed and summarized. The excellent photocatalytic performance of BiVO4 also enables its application to more than just PEC and CO2 reduction. Finally, through the review of this paper, we hope to make a contribution to the ideas and synthesis of BiVO4 photocatalysts with better comprehensive properties.
