“…3 f, the clear lattice fringe of 0.515 nm and 0.502 nm can be distinctly identified, which corresponds to the (110) and (011) planes of CM, respectively. Compared with reported laboratory-produced CM nanoparticles (rod-like and dot-like) 12 , 35 – 37 , the industrially prepared flakes are more homogeneous in size; nano-flake-shaped particles can expose more surface area; thus, they can release more Cu ions. These can improve antifungal properties.…”

In the last few decades, nanoparticles have been a prominent topic in various fields, particularly in agriculture, due to their unique physicochemical properties. Herein, molybdenum copper lindgrenite Cu3(MoO4)2(OH)2 (CM) nanoflakes (NFs) are synthesized by a one-step reaction involving α-MoO3 and CuCO3⋅Cu(OH)2⋅xH2O solution at low temperature for large scale industrial production and developed as an effective antifungal agent for the oilseed rape. This synthetic method demonstrates great potential for industrial applications. Infrared spectroscopy and X-ray diffraction (XRD) results reveal that CM samples exhibit a pure monoclinic structure. TG and DSC results show the thermal stable properties. It can undergo a phase transition form copper molybdate (Cu3Mo2O9) at about 300 °C. Then Cu3Mo2O9 nanoparticles decompose into at CuO and MoO3 at 791 °C. The morphology of CM powder is mainly composed of uniformly distributed parallelogram-shaped nanoflakes with an average thickness of about 30 nm. Moreover, the binding energy of CM NFs is measured to be 2.8 eV. To assess the antifungal properties of these materials, both laboratory and outdoor experiments are conducted. In the pour plate test, the minimum inhibitory concentration (MIC) of CM NFs against Sclerotinia sclerotiorum (S. sclerotiorum) is determined to be 100 ppm, and the zone of inhibiting S. sclerotiorum is 14 mm. When the concentration is above 100 nm, the change rate of the hyphae circle slows down a little and begins to decrease until to 200 ppm. According to the aforementioned findings, the antifungal effects of a nano CM NFs solution are assessed at different concentrations (0 ppm (clear water), 40 ppm, and 80 ppm) on the growth of oilseed rape in an outdoor setting. The results indicate that the application of CM NFs led to significant inhibition of S. sclerotiorum. Specifically, when the nano CM solution was sprayed once at the initial flowering stage at a concentration of 80 ppm, S. sclerotiorum growth was inhibited by approximately 34%. Similarly, when the solution was sprayed once at the initial flowering stage and once at the rape pod stage, using a concentration of 40 ppm, a similar level of inhibition was achieved. These outcomes show that CM NFs possess the ability to bind with more metal ions due to their larger specific surface area. Additionally, their semiconductor physical properties enable the generation of reactive oxygen species (ROS). Therefore, CM NFs hold great potential for widespread application in antifungal products.

“…Further, the photocurrent density of the obtained Cu 3 (MoO 4 ) 2 (OH) 2 nanosheets is higher than 2.9 μA⋅cm À 2 of the Cu 3 (MoO 4 ) 2 (OH) 2 films reported by the literature. [33] The results show that the exposed (010) facet of Cu 3 (MoO 4 ) 2 (OH) 2 nanosheets is one of the most active surfaces, so that Cu 3 (MoO 4 ) 2 (OH) 2 nanosheets have excellent photoelectric performance and have potential research value as a photocatalyst in the absorption and utilization of visible light. 11).…”

“…[30][31][32] Currently, there are fewer reports on Cu 3 (MoO 4 ) 2 (OH) 2 photocatalytic application, and there is a literature report that Cu 3 (MoO 4 ) 2 (OH) 2 film is used as a photocatalyst to convert carbon dioxide into other compounds, such as methanol, formic acid and hydrogen. [33] But its utilization is low, so the preparation of high efficient Cu 3 (MoO 4 ) 2 (OH) 2 photoelectrode is very meaningful. [34][35] Since the photocatalytic reaction occurs on the surface of the photocatalyst, the surface structure of the catalyst can affect its photocatalytic activity.…”

The monoclinic Cu 3 (MoO 4 ) 2 (OH) 2 nanosheets exposed mainly as (010) facet were successfully prepared by a hydrothermal method using orthorhombic phase (NH 4 ) 2 Mo 4 O 13 nanosheets as the raw materials. The formation mechanism from the layered (NH 4 ) 2 Mo 4 O 13 nanosheets to the Cu 3 (MoO 4 ) 2 (OH) 2 nanosheets in the reaction was discussed in detail. The crystal structure and morphology of Cu 3 (MoO 4 ) 2 (OH) 2 nanosheets were revealed by XRD, FE-SEM, TEM, SAED, UV-vis DRS, EDX, XPS, FTIR and Raman spectroscopy. Furthermore, the photocatalytic performance of the Cu 3 (MoO 4 ) 2 (OH) 2 nanosheets as a photocatalyst was evaluated by splitting water under the simulated sunlight. The results showed that the photocurrent density and the generated H 2 of the prepared sample Cu 3 (MoO 4 ) 2 (OH) 2 nanosheets are 20.7 μA⋅cm À 2 and 154.5 μmol⋅h À 1 ⋅g À 1 , respectively, which are 0.7 times higher than those generated by the control ST01. The results indicate that the Cu 3 (MoO 4 ) 2 (OH) 2 nanosheets have potential application value in photocatalysts and photovoltaic nanodevices.
