Effect of activating agents on the photocatalytic activity of chromium oxide based porous carbon photocatalysts derived from chrome-tanned leather buffing dust waste for the degradation of 2-chlorophenol

Phase Engineering of Titanium Oxynitride System and Its Solar Light-Driven Photocatalytic Dye Degradation, H2 Generation, and N2 Fixation Properties

“…Furthermore, the interfacial charge transfer resistance characteristics of the systems are investigated using the EIS technique, and the obtained Nyquist plots are shown in Figure c and the inset. The arc radius corresponding to TON850 (oxynitride) is found to be several orders smaller, compared to the oxide (TON750) and slightly larger in comparison with the nitride (TON950) . This observation suggests that the oxynitride phase possibly establishes an Ohmic interface in the system that drives the charge carriers rapidly to the surroundings with the least resistance.…”

The transient photocurrent conductivity graphs of the samples are obtained over a total period of 250 s with 10 s ON-OFF cycles, and the results are given in Figure 10d.…”

Collagen fiber-reinforced, tough and adaptive conductive organohydrogel e-skin for multimodal sensing applications

“…23 A unique material, buffing dust (BD), has attracted our attention; it is a leather waste with a composition similar to human skin, with abundant production, collagen-containing fiber structure and lowcost characteristics. 24,25 Secondly, conductivity and antimicrobial properties need to be considered when preparing FSDs. Carbon quantum dots (CQDs), as a zero-dimensional carbon material with excellent electrical conductivity, water solubility and biocompatibility, have been widely reported in the fields of medical imaging, environmental monitoring and chemical analysis.…”
