Special Issue Information

Dear Colleagues,

Lignocellulosic biomass has been considered one of the most promising feedstocks for the production of biofuels and biomaterials following the depletion of petroleum. However, the hierarchical and multi-layered structure of lignocellulose cell wall is the major barrier for the efficient conversion of lignocellulose to value-added products such as biofuels. Advanced pretreatment methods with low economic cost, high efficiency, and less environmental pollution are needed to firstly convert lignocellulose to platform chemicals which can be further synthesized through various biofinery processes to proceed liquid biofuels, solid biofuels, gas biofuels, and other energy storage materials. Thus, the novel facility, biofinery process, and green technologies to integrate lignocelluslose extraction and transformation into a wider spectrum of marketable and value-added products are explored in the current Special issue “Lignocellulose Based Biofuels and Biomaterials”.

This research investigated the synthesis of biochar through the direct pyrolysis of pre-roasted sunflower seed shells (SFS) and peanut shells (PNS) and compared their application for the effective removal of textile dyes from wastewater. Biochar prepared at 900 °C (SFS900 and PNS900) showed the highest adsorption capacity, which can be attributed to the presence of higher nitrogen content and graphite-like structures. CHNS analysis revealed that PNS900 exhibited an 11.4% higher carbon content than SFS900, which enhanced the environmental stability of PNS biochar. Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analyses of the produced biochar indicated the degradation of cellulosic and lignin moieties. X-ray photoelectron spectroscopy (XPS) revealed a 13.8% and 22.6% increase in C-C/C=C mass concentrations in the SFS900 and PNS900, respectively, and could be attributed to the condensation of polyaromatic structures. Batch experiments for dye removal demonstrated that irrespective of dye species, PNS900 exhibited superior dye removal efficiency compared to SFS900 at similar dosages. In addition to H-bonding and electrostatic interactions, the presence of pyridinic-N and graphitic-N can play a vital role in enhancing Lewis acid-base and π-π EDA interactions. The results can provide valuable insights into the biochar–dye interaction mechanisms. Full article
