“…1(B), the presence of characteristic peaks at 3460 and 1620 cm −1 can be observed on the FT-IR spectrum of C-ZIF-67, which are free –COOH groups and the stretching vibration of CO groups, respectively. The FT-IR spectrum of SP exhibits characteristic peaks at 3460, 1620, and 1384 cm −1 , which are similar to those of other researchers, 41 representing the stretching vibration of CO groups, bending vibration of C–H groups, and stretching vibration of C–O groups, respectively. Overall, the presence of the characteristic peaks in C-ZIF-67/SP for the XRD patterns and FT-IR spectrum reflecting both C-ZIF-67 and SP confirms that the desired modified materials were successfully prepared.…”

“…The straight-line region was the low-frequency region and represented the migration and diffusion of ions inside the electrode. The semicircular region was the high-frequency region, indicating the electrolyte and electrode internal resistance ( R Ω). , The EIS data are fitted with the Nyquist plot in the inset of Figure a. The FP-doped gCN nanosheets had a lower charge transfer resistance ( R ct ) due to a lower semicircle EIS curve in the high-frequency region.…”

In this article, we present the preparation of a novel heteroatom halogen (fluorine) and nonmetal phosphorus-doped layered graphitic carbon nitride, via the thermal decomposition technique, and examined its electrochemical monitoring ability for vanillin detection. The materials’ basic properties have been observed with various analytical analyses such as X-ray diffractometry, field-emission scanning electron microscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy. The proposed electrochemical sensor material was examined under various operating conditions to demonstrate a good current response for vanillin sensing. The sensor has a wide linear range (0.2–100 μM) and a lower limit of detection (LoD = 15 nM) with an enhanced sensitivity of 1.80 μA μM–1 cm–2. Ultimately, the potential utility of the suggested sensor was effectively tested on food samples, demonstrating exceptional recoveries of 99.46 and 96.76% for coffee and vanilla ice cream, respectively, with corresponding relative standard deviations of 1.83 and 1.21 for each.

There are several industrial uses for carbon black (CB), an extremely fine powdered form of elemental carbon that is made up of coalesced particle aggregates and almost spherical colloidal particles. Most carbon black is produced from petroleum-derived feedstock, so there is a need to find an alternative method to produce CB, which relies on renewable resources such as algae and agricultural waste. A process involving hydrolysis, carbonization, and pyrolysis of green algae and sugarcane bagasse was developed, as the optimal hydrolysis conditions (16N sulfuric acid, 70 °C, 1 h, 1:30 g/ml GA or SC to sulfuric acid ratio), a hydrolysis ratio of 62% for SC and 85% for GA were achieved. The acidic solution was carbonized using a water bath, and the solid carbon was then further pyrolyzed at 900 °C. The obtained carbon black has a high carbon content of about 90% which is confirmed by EDX, XRD, and XPS analysis. By comparison carbon black from sugar cane bagasse (CBB) and carbon black from green algae Ulva lactuca (CBG) with commercial carbon black (CCB) it showed the same morphology which was confirmed by SEM analysis. The BET data, showed the high specific surface area of prepared CB, which was 605 (m2/g) for CBB and 424 (m2/g) for CBG compared with commercial carbon black (CBB) was 50 (m2/g), also the mean pore diameter of CBB, CBG and CCB indicated that CBB and CBG were rich in micropores, but CCB was rich in mesoporous according to IUPAC classification. This study might have created a technique that can be used to make carbon black from different kinds of biomass.
