ZnS@ reduced graphene oxide nanocomposite as an effective sunlight driven photocatalyst for degradation of reactive black 5: A mechanistic approach

Evaluación de la actividad fotocatalítica de compósitos ZnS-rGO

“…En los difractogramas de las muestras de ZnS-rGO no se aprecia el pico característico del rGO en el ángulo 27.49°, lo cual se debe a dos razones: (1) la cantidad de rGO presente en los compósitos ZnS-rGO es mucho menor a la de ZnS y, (2) el pico de rGO es opacado por el pico del plano (111) del ZnS (28.74°). [13][14][15] Sin embargo, el pico de rGO se puede apreciar levemente en el difractograma de la muestra ZnS-rGO_40. Con la ecuación de Scherrer se determinó el tamaño del cristalito de las muestras, D111, siendo 33.6, 29.7, 23.4, y 28.2nm para las muestras de ZnS, ZnS-rGO_20, ZnS-rGO_40 y ZnS-rGO_60 respectivamente.…”

Recent progress in semiconductor/graphene photocatalysts: synthesis, photocatalytic applications, and challenges

“… 68 Furthermore, the synthesized ZnS/rGO photocatalyst, with various ratios of rGO, exhibited a red shift in the absorption edge of the synthesized composites while also improving its light-harvesting capability. 69 …”

Folic acid-functionalized l-cys/ZnS:O nanoparticles for homologous targeting and photodynamic therapy of tumor cells

“…Photodynamic therapy (PDT), as a clinically approved treatment modality, refers to the generation of cytotoxic reactive oxygen species (ROS) by photosensitizers (PSs) in the presence of oxygen and irradiation. [18][19][20][21] It has been observed many times that ZnS could produce ROS in catalytic experiments, [22][23][24] but there are few reports on biological applications. In fact, materials with high efficiency of ROS generation in catalysis experiments can also be used for PDT after being modified by biological groups.…”
