One of the main goals of the research has been to understand how cellulose breaks down into simpler fermentable sugars. To do this, the researchers have used a variety of pre-treatment techniques to extract the sugars from cellulose.

Herein, the activated carbon was successfully synthesized from oil palm empty fruit bunch (OPEFB) through chemical activation and carbonization processes with and without the addition of melamine as a nitrogen dopant to generate non-doped (AC) and nitrogen-doped activated carbon (ACN), respectively, and consequently used as a component for anode materials of LIB. The effect of nitrogen doping on the LIB performance of activated carbon-based OPEFB, with the OPEFB: melamine mass ratio variations of 1:1 and 1:2, was investigated. The obtained AC and ACN samples were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Brunauer–Emmett–Teller (BET) analysis, and field-emission scanning electron microscopy (FESEM). The LIB performances were performed by electrochemical characterization such as cyclic voltammetry (CV), charge–discharge (CD), and electrochemical impedance spectroscopy (EIS) analysis. The suppression of specific surface area by the increase of melamine addition from 758.38 to 307.57 m<sup>2</sup> g<sup>−1</sup> contributed to the increase of nitrogen content in OPEFB-activated carbon. As evident from the FTIR analysis, the increase of the C-N bond peak indicates the presence of nitrogen heteroatoms in the activated carbon materials. However, the LIB performance was greatly enhanced by increased doping of OPEFB-activated carbon with nitrogen. The results showed that in the ACN12 sample, the discharge capacity was significantly improved from 219.27 to 314.18 mAh g<sup>−1</sup>. In addition, the ACN12 also exhibits an improvement in coulombic efficiency from 55.57 to 78.98%, which makes it a promising anode material for sustainable and low-cost lithium-ion batteries.</p><h3>Graphical abstract</h3><p>Preparation of N-doped activated carbon-based oil palm empty fiber bunch.</p>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"15 9","pages":"13845 - 13860"},"PeriodicalIF":3.5,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study investigates the morphological and small structural alterations of PTF resulting in modified papaya fibre (MPF). Through this modification, a significant enhancement in the whiteness index of the MPF is achieved, showing a remarkable improvement of 62.79% over the PTF. Subsequently, the MPF is assessed for its efficacy in adsorbing Reactive Red 195 (RR195), Reactive Orange 122 (RO122), and Reactive Blue 221 (RB221) dyes. The MPF demonstrates removal capacities for RR195, RO122, and RB221 of 69.44 mg g<sup>−1</sup>, 69.80 mg g<sup>−1</sup>, and 88.56 mg g<sup>−1</sup> respectively within 60 min. at pH 2 from aqueous solution. It exhibits notable efficacy in removing dyes from real textile effluents with the removal of 58.20% for RR195, 77.26% for RO122, and 61.11% for RB221 in 60 min. Moreover, MPF proves effective in treating combined effluents, achieving a 54.49% reduction in dye concentration. The papaya fibre remaining after dye adsorption exhibit excellent fastness against abrasion in dry condition. Additionally, the study evaluates the potential against a microbial attack of PTF, MPF, and papaya fibre after dye adsorption (PFADA) using gram-positive and gram-negative bacteria.

Upon first characterization using UV–vis spectroscopy, a noticeable absorption peak was seen at 364 nm, corresponding to the ZnO absorption band gap. The crystalline nature of the ZnONPs was confirmed by further structural study using XRD, which showed peaks matching ZnO crystalline phases. TEM revealed the mostly spherical shape of the ZnONPs, with a small size. The photocatalytic degradation experiment of malachite green (MG), the results exhibited a complete degradation (100%) of MG dye after exposure to 100 mg/L of ZnONPs at 90 min under visible light. The recyclability performance of ZnONPs reached 94.2% after 5 cycles. Additionally, antibacterial potential was evaluated of ZnONPs against <i>Salmonella enterica</i>, <i>Pseudomonas aeruginosa</i>, <i>Staphylococcus aureus</i>, and <i>Enterococcus faecalis</i>.
