Abstract Climate change issues are calling for advanced methods to produce materials and fuels in a carbon–neutral circular way. For instance, biomass pyrolysis has been intensely investigated during the last years. Here we review of algal lignocellulosic with focus on products mechanisms, oil upgrading, combining anaerobic digestion, economy, life cycle assessment. Products include oil, gas, biochar. Upgrading techniques comprise hot vapor filtration, solvent addition, emulsification, esterification transesterification, hydrotreatment, steam reforming, use supercritical fluids. We examined economic viability terms profitability, internal rate return, return investment, carbon removal service, product pricing, net present value. also reviewed 20 recent studies found that method highly influenced yield, ranging from 9.07 40.59% 10.1 41.25% biochar, 11.93 28.16% syngas. Feedstock type, pyrolytic temperature, heating rate, reaction retention time were main factors controlling distribution products. Pyrolysis mechanisms bond breaking, cracking, polymerization re-polymerization, fragmentation. Biochar residual forestry could sequester 2.74 tons dioxide equivalent per ton biochar when applied soil thus potential remove 0.2–2.75 gigatons atmospheric annually. The generation bio-oil process is estimated be economically feasible.

The increased demand for energy has driven researchers to concentrate on generating secure sources humanity. One advantage of inventing a biological and chemical way generate green efficient electrical is that it eliminates dependency soon-to-extinct fossil fuels. Biofuels are one many emerging sectors receiving major attention, all which alternative Carbon-based nanomaterials, due their larger surface area, affordability, ability withstand high temperatures, have been engineered serve as electrocatalysts without the need metals. These nanomaterials can also provide stable structure metal-based electrocatalysts, enabling conversion biofuels into environmentally friendly sources. Thus, biofuel synthesis "greener" using its catalyst. Graphite, carbon nanoparticles, nanotubes, nanohorns, nanorods be used construct build wide range biofuels. This review gives insight how carbon-based across different stages production, along with corresponding issues possibilities. Moreover, emphasizes utilization diverse nano-biocatalysts enhance production by increasing yield. Given possible uses, research in concern exhibits seemingly indefinite scope.

21Carbon quantum dots with honeycomb structure: a novel synthesis approach utilizing cigarette smoke precursors
Scientific Reports, Год журнала: 2024, Номер 14(1)
Опубликована: Янв. 23, 2024
Abstract This study presents a novel approach to synthesizing honeycomb carbon quantum dots (CQDs) from cigarette smoke by hydrothermal process. A comprehensive characterization of these CQDs, conducted through high-resolution transmission electron microscopy (HRTEM), showcases their unique structure, with an average particle size 6.3 nm. Photoluminescence (PL) in CQDs is captivating phenomenon where nanoscale structures emit strong blue luminescence at 461 nm upon exposure ultraviolet light, excitation peak occurring 380 Fourier Transform Infrared (FTIR) analysis also identifies specific functional groups within the offering valuable insights into mechanisms governing photoluminescence. Analysis spectra indicates presence both aromatic C=C bonds 254 and C–O 280 420

The coconut tree (Cocos nucifera) stands as a pivotal resource in tropical regions, playing crucial role both subsistence and economic activities across Asia, the Pacific Islands, South America. While harvesting of fruit is essential for producing globally utilized edible products, such oil, by small owners large producers around world food, cosmetics, pharmaceutical industries, concerns have arisen due to substantial amount agro-industrial residue generated this process, posing environmental risks if they are not properly managed. Recognizing challenges, paper emphasizes transformative potential inherent waste, characterized its lignocellulosic composition rich lignin multifunctional groups. By delving into historical context exploration chemical composition, review explores diverse applications focusing on utilization processing residues generate sustainable products byproducts. Ultimately, comprehensive underscores significance repurposing only mitigate impact but also valuable contributor circular economy, promoting use biomass research bolstering raw material energy sectors.
