Novel antibacterial application of photovoltaic Cu₂SnS₃ (CTS) nanoparticles

Abstract

In the present work, Cu2SnS3 (CTS) nanoparticles were synthesized using the hot injection method.

In Situ Phase Separation into Coupled Interfaces for Promoting CO2 Electroreduction to Formate over a Wide Potential Window

“…[9] In addition, the X-ray diffraction (XRD) pattern of as prepared products matched the characteristic peaks of monoclinic Cu 2 SnS 3 materials (Figure S1). [14] Fur-thermore,t he average thickness of the obtained materials were determined to be around 4.4 nm (Figure 1d). TheCu, Sn and Se lements were homogeneous spatial distributions throughout the ultrathin nanosheets (Figure 1e and f), while the Oe lement may be due to the partial oxidation of the ultrathin Cu 2 SnS 3 nanosheets by the air.…”

“…Electrostatic interaction between opposite charges can be the mechanism for antibacterial activity of AgNPs. As evaluated from their isoelectric point,39 the NPs have a net positive charge and bacterial cell walls have a net negative charge. The interaction between AgNPs and the cell membrane components breaks cell walls and destroys the cells.…”

Temperature-dependent Raman spectroscopy of Cu2Sn1− x Ge x S3 thin films

“…[1][2][3][4][5][6][7][8][9][10] Recently, the photovoltaic cells based on the CTGS absorbers exhibited a power conversion efficiency over 6%, which is an impressive achievement. 10) By optimizing the characteristic of CTGS absorbers as well as device structure, efficiency over 25% is expectable in the future according to the detailed balance theory.…”

“…11) However, the study of CTGS compound is still immature and reports concerning to this compound are relatively few compared to the well-developed absorber materials such as Si, GaAs, Cu(In,Ga)Se 2 , CdTe, and Cu 2 ZnSn(S,Se) 4 . [1][2][3][4][5][6][7][8][9][10][12][13][14][15][16][17] Besides, formation of different crystal phases as well as unintended secondary phases is one of the major problems for this material system due to its multinary elemental composition. [18][19][20][21][22][23][24][25][26][27][28] Hence, it is important to explore the material properties relating to its impurity phases as well as fabrication techniques of CTGS multinary compound by various theoretical and experimental approaches in order to improve its characteristics.…”
