“…The degradability of a Rhodamine B dye was monitored by change in its absorption peak at 554 nm. As evident from the figure, the degradation efficiency of the Rhodamine B dye by synthesized ZnO NPs and its calcium composite increased with time [42][43][44] . Although, it has been reported that Rhodamine B dye degrades very slowly, our synthesized samples could effectively degrade it (Figure 6(d-f)).…”

Zinc oxide is considered an effective photocatalyst for degradation of several organic contaminants found in wastewater. This work reports the biological synthesis of zinc oxide nanoparticles and its calcium nanocomposites to study the photocatalytic deterioration of two dyes, viz. Rhodamine B and Methylene blue, under natural sunlight. Nanoparticles were synthesized using zinc acetate and starch extracted from potato at pH 7–8. Potato starch acts as both a capping agent and a reducing agent. They were characterized spectroscopically via XRD, SEM, HR-TEM, EDAX and FT-IR techniques. Bean/spherical shaped ZnO NPs were obtained in the size range of 29–49 nm whereas calcium coating on ZnO decreased the particle size, i.e., 25–35 nm. Their photocatalytic ability to degrade Rhodamine B and Methylene blue was studied under natural sunlight and monitored using UV-Vis spectrophotometer. Synthesized ZnO nanoparticles and its calcium coated ZnO nanocomposites showed promising results in degradation of these dyes. Methylene blue was completely degraded in an hour at 8 mg of the sample. Although degradation of Rhodamine dye was slow, synthesized samples were effective catalysts as compared to the ones reported in the literature.

“…The improvement in photocatalytic activity can be attributed to the following two factors: the increase in the interlayer spacing, which increases the surface contact, and nitrogen doping. 215 The silver-doped titanate nanosheets were synthesized by a solvothermal method. The presence of silver facilitates the migration of photogenerated electrons to silver atoms and reduces the recombination rate of photogenerated electron− hole pairs.…”

As a typical cation-exchangeable layered compound, layered titanate has a unique open layered structure. Its excellent physical and chemical properties allow its wide use in the energy, environmental protection, electronics, biology, and other fields. This paper reviews the recent progress in the research on the structure, synthesis, properties, and application of layered titanates. Various reactivities, as well as the advantages and disadvantages, of different synthetic methods are discussed. The reaction mechanism and influencing factors of the ion exchange reaction, intercalation reaction, and exfoliation reaction are analyzed. The latest research progress on layered titanates and their modified products in the fields of photocatalysis, adsorption, electrochemistry, and other applications is summarized. Finally, the future development of layered titanate and its exfoliated product two-dimensional nanosheets is proposed.

A novel nonwoven‐fabric‐supported‐nano‐Ag (NWF/Ag) reactor was obtained via a mussel‐inspired in‐situ fabrication method. The resulting NWF/Ag features a high catalytic activity for the reduction reaction of organic dyes in the presence of sodium borohydride. More importantly, it is also feasible for the scale‐up catalysis in NWF/Ag‐assembled continuous‐flow reactors. Such a NWF/Ag catalyst preserves the fiber‐based three‐dimensional architecture to effectively drive the continuous‐flow catalysis reactions at unprecedented efficiency, benefiting from it the easy diffusion of dye molecules to access the active catalytic sites of nano‐Ag. Moreover, the resulting NWF/Ag composites can serve as versatile platforms to assemble continuous‐flow reactors in different shapes, sizes, and configurations to extend the catalysis applications. In this study, the catalytic reduction conversion of methylene blue can reach more than 98 % in 270 seconds using the NWF/Ag‐based channel‐type continuous‐flow reactor. It also preserves good catalytic reduction performance to other organic dyes, including methyl orange and acid orange 7. The NWF‐based platforms, combined with a rational designed approach of surface functionalization and hybridization, probably provide new insights into the catalytic reduction of organic dyes in a continuous‐flow way.
