“…It was determined that microporous activated carbons were obtained by activation, especially on the impregnation rate. Similar findings have been reported in studies on obtaining activated carbon by chemical activation of the grape stem [36] and vine branch [37] with H3PO4. The high impregnation rate also confirms that it has an important effect on obtaining activated carbon-containing carbon ( Table 2).…”

In this study, activated carbon has been obtained by using sea urchin as an adsorbent substance, which is abundant, cheap, and natural in nature, as an alternative to active carbon used in heavy metal removal. Using the Ultrasound-assisted support, 1:1, 2:1, 3:1 (H3PO4/sea urchin) carbonization process was carried out by subjecting H3PO4 as the sea urchin activating agent. The BET surface area of the activated carbon obtained was characterized by total pore volume, ash content, and SEM analysis. Cu (II) removal in aqueous solutions were investigated with activated carbons. Experimental studies have been conducted to determine the effects of pH, contact time (min), adsorbent concentration (g/L), temperature, and initial metal concentration parameters affecting adsorption. The adsorption capacity of the activated carbon obtained from the sea urchin at 25 °C was calculated as 643 mg/g. Optimum conditions from the results were determined as pH 2.0, contact time 80 minutes, initial adsorbent concentration 10 mg/L, and temperature 25 °C. According to the results of the study, it has been concluded that the activated carbon obtained from the sea urchin can be an alternative adsorbent to other activated carbons in heavy metal removal.

“…Figure 1 clearly shows that VSAC has a more ordered morphology than GSAC, having larger macropores but containing a superior number of nanopores, which is reflected in the much higher BET surface area of the former.

“…Activated bio-based carbons (VSAC and GSAC) were prepared following the procedure described in our previous papers [27,28]. Namely, the chemical activation synthesis method was used as this method normally leads to carbons of higher surface area than those obtained by the physical activation method.…”

“…Two of the supports were novel, low-cost, activated biomass-derived carbons, namely, vine shoot activated carbon (VSAC) prepared from vine shoots [27] and grape stalk activated carbon (GSAC) prepared from grape stalks [28]. For comparison purposes, the third support material tested was Vulcan XC72, a benchmark carbon support widely used in industrial applications [26].…”

Vine Shoots and Grape Stalks as Carbon Sources for Hydrogen Evolution Reaction Electrocatalyst Supports

Activated bio-based carbons produced from vine shoots (VSAC) and grape stalks (GSAC), which have larger surface area and total pore volume than most of the commercially available activated carbons, are used as supports for palladium nanoparticles (Pd NPs). The prepared materials are characterised by elemental analysis, N 2 -sorption, X-ray diffraction, scanning electron microscopy with energy dispersive X-ray spectroscopy, and transmission electron microscopy analysis and are then assessed as potential cathodes for the hydrogen evolution reaction (HER) in alkaline media. The electrocatalysts' performance for HER is evaluated from cathodic polarisation curves at different temperatures and compared to that of Vulcan XC72-supported Pd NPs. Additional chronoamperometry studies helped to assess the electrocatalysts' activity stability. The novel VSAC-supported Pd electrocatalyst exhibits good HER activity in terms of high current density at low overpotentials, leading to the best performance.

Thermal pyrolysis of mixed date stones and pistachio shells in a semi‐batch reactor was addressed in this study. The highest yield of liquids (51.20 %) was produced at 500 °C, 90 min, 20 °C/min heating rate, and 50 mesh particle size. Under these conditions, yield of liquid from date stones and pistachio shells separately was 49.12 % and 47.67 %, respectively. The FT‐IR results confirmed the presence of multiple oxygen‐containing compounds in the bio‐oil. Results from GC–MS declared that it was predominately composed of acids (57.57 %), esters (21.35 %), phenols (4.63 5), and alcohols (3.49 5). The obtained biochar was transformed into activated carbon (AC) by the optimized ZnCl2 activation method. The ideal AC was synthesized at 600 °C for 60 min using a 2 : 1 ZnCl2: biochar impregnation ratio. FESEM and XRD measurements showed that the AC was amorphous. The prepared AC was effective in eliminating dibenzothiophene (DBT) from model fuel (200 ppm DBT/hexane) with a maximum performance 95.26 % at 40 °C for 1h using 0.35 g of the AC. The exhausted AC was regenerated and reutilized 4 times, and removal efficiency reached 88.23 % in the 4th cycle under ideal working conditions.
