“…Disperse dyes are widely used in the textile industry for dyeing mainly polyester, synthetic fabrics, acrylic and polyamide materials, etc. (14)(15)(16)(17) Degradation of these dyes is quite challenging because these dyes contain a nonionic end, which makes them hydrophobic in nature. (18)(19)(20) Due to the solubility problem, disperse dyes are poor candidates for mechanistic studies.…”

Bioinspired mesoporous activated carbon was synthesized using rice husks. SEM (scanning electron microscopy), XRD (X-ray powder diffraction), FTIR (fourier transform infrared spectroscopy), and BET(Brunauer-Emmett-Teller) were used to detrmine the textural qualities and physicochemical properties of the produced activated carbon .Monolayer and multilayer isotherm models were evaluated to examine the adsorption investigations on hydrophobic Scarlet RR. The Langmuir adsorption isotherm best explained the results because the monolayer's adsorption capacity was 996 mg/g at adsorbent dosage of 1.5 g/L. The results suggested that bio-inspired activated carbon would work well as an adsorbent for dye removal from polluted water.

The utilization of coconut shells as fuel still has several obstacles, including nonuniform size, low heating value, and low density. Pyrolysis of coconut shells into biochar is used to increase the calorific value and minimize the formation of smoke when burning. Biochar briquetting is needed to increase energy density and uniform size. The purpose of this study was to determine the effect of the type of binder and the concentration on the characteristics of biochar briquettes. The binder used were molasses, cow manure, and horse manure. Molasses is most suitable for use as a binder because it has sticky properties and sufficient moisture content. The ratio of biochar: molasses 70:30 produces briquettes with the best characteristics. In the drop test with a height of 1 m and 1.8 m, biochar briquettes with molasses binder still have 99% size stability.

The experimental study is the best way to find out the characteristics of activated carbon (AC) due to its very difficult definition based on its structural formulation or chemical analysis as an effect of its high degree of imperfection in the crystal structure. This experimental study’s objectives are to investigate the characteristics and the adsorption capacities of activated carbon generated from used brewed coffee. The carbonization procedure took place at a temperature of 600 °C. After being made into pellets and powder, the charcoal was heated to 600 °C and activated with the help of 150 mL of nitrogen flowing per minute. Thermogravimetric analyzer (TGA), scanning electron microscopy (SEM), and the adsorption isotherm test were all utilized in the characterization process. The results showed that for pelleted activated carbon (AC-Plt) and powdered activated carbon (AC-Pw), respectively, both activated carbons had average pore diameters in the mesopore category of 4.39 and 4.93 nm. In comparison to AC-Pw, AC-Plt has a larger specific pore surface area (105.857 cm3/g) and pore volume (0.164 cm3/g). The adsorption capabilities of AC-Plt, which has a bimodal pore size distribution, are greater than those of AC-Pw for nitrogen, CO2, and methylene blue. In this investigation, it was discovered that pelleted activated carbon was more suited for the adsorption of nitrogen, CO2, and methylene blue. HIGHLIGHTS The used brewed coffee was successfully converted into powdered and pelleted activated carbons using nitrogen as an activator agent through physical activation The use of natural binder to produce pelleted activated carbon undergoes pyrolysis during the activation process, producing gas that acts as an activating agent (e.g., CO2) so that nitrogen and CO2 work simultaneously and more effectively to develop more activated carbon pore structures Pelleted activated carbon has a higher specific pore surface area of 105.857 cm3/g, pore volume of 0.164 cm3/g, and better adsorption capabilities for nitrogen (75.252 cm3/g), CO2 (1.554 mmol/g) and methylene blue (1.215 mg/g) adsorptions than powdered activated carbon GRAPHICAL ABSTRACT
