“…However, when the concentration of UNM exceeded 700 mg/L, the number of UNM particles exceeded the threshold, leading to an overlap of particles and a reduction in the effective contact with RhB, thus slowing the degradation rate. Additionally, the excess catalyst may have caused light scattering, which affected the light transmission of the solution, 39 resulting in a decrease in the degradation rate of RhB. Consequently, a concentration of 700 mg/L can be selected for further experiments.…”

The β-NaYF4:Yb,Tm,Gd/Ni-MOF (UCNR/Ni-MOF, UNM) nanocomposites were successfully synthesized via a simple two-step hydrothermal method. Excited by a 980 nm laser, UCNRs produce ultraviolet and visible light, activating the Ni-MOF and generating a significant quantity of electron/hole pairs (e–/h+). These e–/h+ pairs can then react with O2 and H2O to create reactive oxygen species (ROS), which can be used for antibacterial purposes. Characterization techniques including transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) were utilized to analyze the structure, optical properties, composition, and morphology of the UNM nanocomposites. The photocatalytic performance of UNM was evaluated by testing its ability to kill E. coli and S. aureus as well as degrade rhodamine B (RhB) under 980 nm near-infrared light irradiation (1.0 W/cm2). After 18 min of reaction, the bactericidal rates against E. coli and S. aureus were observed to be roughly 100 and 99.99%, respectively. Similarly, ∼98.49% of RhB was degraded within 180 min. Free radical capture experiments were conducted to further investigate the mechanism of UNM photocatalysis. The main active species involved were determined to be ·O2 – and h+. In addition, UNM was able to retain ∼86.25% of its degradation rate toward RhB after four cycles of cycling experiments, which demonstrated its good stability. Therefore, this study provides a potential strategy to eliminate bacteria and degrade hazardous pollutants in order to mitigate environmental pollution.

The use of novel two-dimensional MXene materials and conventional g-C3N4 photocatalysts to fabricate the composites for hydrogen evolution reaction (HER) has attracted much attention, for which there is plenty of room for the enhancement of hydrogen evolution rates particularly under visible light and photostability. Herein, g-C3N4 was modified by copolymerization of malonamide and melamine and used to fabricate the ternary composites of Au particles and Ti3C2 MXene, and based on the synergistic effect, the composites enhanced the hydrogen evolution rates by 2.1, 99.8, and ∞ times compared with the unmodified g-C3N4 under UV, simulated sunlight, and visible light illumination, respectively. Moreover, the composite exhibited a sustained hydrogen evolution capacity in the cycle test for up to 120 h. Theoretical calculations and experimental results indicated that the hot electrons of Au are injected into the modified g-C3N4 and transferred to Ti3C2 simultaneously along with the photogenerated electrons of the modified g-C3N4 and then further transferred to Au, forming a photogenerated electron transfer channel of Au and modified g-C3N4 → Ti3C2 → Au within the composite. Ti3C2 acts as a bridge for fast separation of photogenerated electrons and holes on Au and modified g-C3N4, playing a key role in the enhanced photocatalytic performance. In addition, the visible light absorption ability of Au also positively contributed to the enhancement of visible light photocatalytic performance by providing hot electrons. Therefore, the selection of suitable cocatalysts for the design of composites is a crucial research direction to improve the photocatalytic performance and photostability of photocatalysts.

“…3 Therefore, the technology of using solar energy to split water to produce hydrogen possesses inestimable advantages and potential, and the key to this technology is to create an efficient and environmentally friendly photocatalyst. [4][5][6] The candidate photocatalyst materials must conform to the characteristics of rich resources, environmental protection, and good light absorption. Since graphene was successfully stripped in the laboratory, 7 two-dimensional (2D) materials have quickly entered the public's field of vision.…”
