Abstract:
... This paper synthesized a new type of ternary piezoelectric catalyst MoOₓ/ZnS/ZnO (MZZ) by a one-step method. The catalytic degradation of Rhodamine B (RhB) solution (10 μg/g, pH = 7.0) shows that the composite catalyst has excellent piezoelectric catalytic activity under ultrasonic vibration (40 kHz). The piezoelectric degradation rate of the optimal sample reached 0.054 min⁻¹, which was about 2.5 ...

Abstract:
... Removing large concentrations of organic pollutants from water efficiently and quickly under visible light is essential to developing photocatalytic technology and improving solar energy efficiency. This study used a simple hydrothermal method to prepare a non-metallic, S-doped NaTaO₃ (S-NTO) photocatalyst, which was then loaded onto biochar (BC) to form a S-NTO/BC composite photocatalyst. After u ...
... The metallic nanogap has been proved as an efficient architecture for surface-enhanced Raman scattering (SERS) applications. Although a lot of nanogap fabrication methods have been proposed in the last few decades, the economical and high-yield manufacturing of sub-10 nm gaps remains a challenge. Here, we present a convenient and cost-effective fabrication method for wafer-scale patterning of meta ...
... Flexible surface-enhanced Raman scattering (SERS) substrates show great potential application in environmental, biological and technological sensors. However, most of flexible SERS substrates are designed based on depositing or embedding metal (Ag, Au, Cu) particles on or into polymer supports or woven fibers without SERS activity, which suffer from complex manipulation processes and high cost. In ...

Macro- and nanosized core, as well as core–shell, γ-cyclodextrin metal–organic frameworks (γ-CD-MOFs) have been designed and used as platforms for the encapsulation of dye molecules to develop the first CD-MOF-based ratiometric optical thermometer materials. A novel dye combination was employed for this purpose, i.e., the duo rhodamine B (RhB) and fluorescein (FL). RhB is highly temperature-sensit ...
