In this study, we report a metal-free photocatalyst, Acetylenyl-TPB-DMTP-COF, which efficiently degrades organic dyes under both UV and visible light, without requiring metal doping or sacrificial agents.

Rapid industrialization has led to significant environmental challenges, particularly in wastewater treatment, where the removal of heavy metal ions and organic dyes is critical....This study presents the synthesis and characterization of a high-performance hydrogel adsorbent, (nanoclay)x@poly-γ-glutamic acid (γ-PGA)/polyethyleneimine (PEI) hydrogel adsorbent (denoted as NxPP, x = 0, 20, 40, 60, and 80), for the efficient removal of heavy metal ions (Cu2+, Fe3+, and Zn2+) and organic...dyes (Methylene blue, as a typical example) from wastewater.

However, traditional probes such as organic dyes and quantum dots present challenges such as photobleaching and blinking variability, which limit their application in super-resolution imaging, particularly in non-liquid environments.

The surface deposition of noble metals can effectively improve photocatalytic performance by the effect of electron trapping (ET) or surface plasmon resonance (SPR), but it is not clear which effect dominates the photocatalytic degradation of organic dyes under light irradiation at specific wavelengths

Helicenes are chiral organic dyes that are attracting growing attention due to the high tunability of their (chir)optical and electronic properties. In this work, a series of functionalized cationic diaza[4]helicenes based on dimethoxyquinacridinium (DMQA) scaffolds are presented.

The sensitivity of the synthesized nanocomposites was tested using typical representatives of organic dyes and pesticides (rhodamine 6G, crystal violet, and thiram) as probes, which have very low detection limits of 10-12, 10-11 and 10-9 M, respectively, and good stability was observed.

We also characterized the organic dyes and pigments, such as yellow (PY74), orange (PO36), red (rhodamine), and blue (phthalocyanine) hues used to create colourful images of street art.

Our results demonstrate that the electro-driven filtration process using nanoporous membranes as high-performance anion conducting membranes shows a critical potential in fractionation of organic dyes and inorganic salts, unlocking the proof of concept of nanoporous membranes in electro-driven application

As a proof of concept, we develop an integrated solar-powered desalination system using interconnected HCDI devices, which not only produces desalinated water meeting human consumption standards but also efficiently removes organic dyes and recovers energy.

These experimental results not only offer an ultrafast method for degrading organic dyes but also provide new insights into the interactions between dye solutions and solid surfaces.
