“…The distinct peak located at 1568 cm −1 confirms the presence of C=C bonds [38]. Additionally, the band at 1547 cm −1 is assigned to C-O bonds deformations [39][40][41]. These observed absorption bands provide compelling evidence of the characteristic bonds found in walnut shell powder.…”

Walnut shells were used to produce highly microporous activated carbon. The prepared activated walnut shells were found to be an efficient adsorbent for removing Cr(VI). The study used the response surface methodology to investigate four independent variables effect: Cr(VI) concentration, pH, AC-Ws dose, and temperature on the Cr(VI) removal efficiency, which was studied in the concentration range of 0.1 to 0.3 g/L, 4 to 10, 15 to 35 °C and 1 to 5 mg/L, respectively. Through experiments designed, the optimum conditions were determined to be 4, 0.23 g/L, 298 k, and 2 g/L, respectively. At these conditions, the efficiency of removal was found to be 93%. The thermodynamic study of the adsorption process showed a spontaneous and exothermic nature. The kinetic model that explains the experimental data is the pseudo-second-order model. Furthermore, the Langmuir isotherm model was estimated to be an excellent representation of the equilibrium data. Quantum calculations and NCI analyses were also performed to get more light on the adsorption mechanism of the Cr(VI) atom and its complex form on the prepared AC-Ws surface.

This study utilised coconut husk biochar as an alternative sustainable carbon support for Pd-based electrocatalyst for ethanol oxidation reaction in basic medium. Coconut husk biochar (BC) was prepared via slow pyrolysis at 800 °C for 1 h at a ramp rate of 5 °C min−1. The Pd/BC catalyst was prepared via borohydride-facilitated reduction of palladium chloride solution. TEM analysis revealed good dispersion of the Pd nanoparticles on the biochar support with particle size ranging from 1.9 to 3.4 nm. Cyclic voltammetry (CV) measurements of Pd/BC in 1.0 M ethanol in 0.1 M KOH gave an on-set potential of −0.615 V (versus Ag/AgCl) with a forward peak current density of 23.87 mA cm−2, which is slightly higher than the commercial Pd/C catalyst. The Pd/BC also has a higher electrochemical stability and durability than the commercial Pd/C catalyst based on chronoamperometry studies (i.e., 44.43% versus 39.64% current retention). The synthesised coconut husk biochar–supported Pd catalyst exhibited promising results for ethanol oxidation reaction for alkaline direct ethanol fuel cell application.

“…However, these techniques are not economical and environmentally acceptable. Amongst them, the use of porous materials, such as porous carbon, porous silica, porous alumina, zeolite, and metal-organic framework [ 4 , [13] , [14] , [15] , [16] ] for adsorption process is considered an inexpensive, effective, and easy technique for removing pollutants from the aqueous solution [ 17 , 18 ]. Furthermore, using porous carbon as an adsorbent for antibiotic removal exhibits notable benefits regarding its high adsorption efficiency and comparatively economical aspects than other adsorbent since porous carbons could be developed from several biomass resources via thermochemical processes such as hydrothermal carbonization, carbonization combined with the activation process [ 19 , 20 ].…”
