One-step synthesis of Ag2S/Ag@MoS2 nanocomposites for SERS and photocatalytic applications

Flexible and Reusable Ag Coated TiO2 Nanotube Arrays for Highly Sensitive SERS Detection of Formaldehyde

“…Recently, photocatalytic organic molecular processes have also been successfully detected by SERS. Semiconductor-based composite materials including Ag/TiO 2 , Au/TiO 2 , Ag/SiO 2 , Ag/RGO, Au/ZnO, Cu 2 O/Ag, etc., have been shown to have both SERS activity and photocatalytic degradation activity [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. In particular, semiconductor structures based on one-dimensional arrays have been proven to serve as excellent SERS substrates with higher sensitivity, uniformity, and reproducibility than other structures.…”

Engineering the Interface of Cu/MoS2 Nanostructures for Improved Charge Transfer for Applications as PEC Anode Materials

“…53 Additionally, the XRD patterns of Cu/MoS 2 are similar to MoS 2 , indicating that the decoration of Cu on MoS 2 has no effect on the crystal structure of MoS 2 . 50 The diffraction patterns of CuS are shown in Figure 2a; the diffraction peaks at 27.3 and 48.02°correspond to the (101) and (110) preferred orientations (JCPDS no. 1-1281), respectively.…”

“…Precious metals exhibit a peculiar surface plasmon resonance effect (SPRE) that has a considerable impact on the band gap, photon absorption, and photon emission of semiconductor materials. The SPRE of precious metals allows them to absorb visible light and generate strong inhomogeneous electric fields on the nearby semiconductor surface. − Plasmonic energy can be used as extra energy to inhibit charge recombination and generate a plasmon heating zone to facilitate PEC conversion. − By combining semiconductors with different noble metals − such as Au, Ag, Cu, and Pt, noble metal–MoS 2 nanostructures have been synthesized, thus considerably improving the PEC activity of MoS 2 . Sun et al reported a strategy to efficiently enhance and broaden the photoresponse of MoS 2 hybrid devices using a Au nanoslit array architecture.…”

“…It is crucial to understand the stability and high photocatalytic activity of new two-dimensional (2D) materials with single metal atoms or metal NP-deposited systems. Wu et al 50 synthesized Ag 2 S/ Ag@MoS 2 nanocomposites using a one-step synthesis method and studied their surface-enhanced Raman scattering and applications in photocatalytic degradation of organic pollutants. Cu is an important luminescence activator among II−VI compounds and has properties similar to those of Au and Ag because it is in the same main group.…”

A highly sensitive SERS substrate based on a mesoporous Ag–TiO2 thin film for the detection of dye molecules

“…17 The Ag/Au nanoparticles decorated on ZnO, TiO 2 , MoS 2 nanosheets, nanorods, nanospheres, and nanocomposites have proven useful reusable SERS properties. [23][24][25] In particular, TiO 2 is extensively studied for SERS applications as it is nontoxic, stable and exhibits high photocatalytic activity. 24 We have fabricated a highly sensitive, mesoporous Ag-TiO 2 nanocage film as an SERS substrate using a scalable method.…”
