“…Careful analysis of the spectrum indicates the presence of a peak at wavenumber 3471 cm −1 . The presence of this stretch confirms the biochar’s hydrophilicity, indicative of adsorbed water molecules and the presence of the hydroxyl group (O-H) [ 55 ]. The absorbance at around 2348 cm −1 aligns with the presence of aromatic and aliphatic structures, resonating with C–H and C–C bonds, as documented in the literature [ 27 , 56 ].…”

This study examines the pyrolysis of agricultural residues, namely, coconut shells, rice husks, and cattle manure, in a vertical fixed-bed reactor at varying temperatures from 300 to 800 degrees Celsius for biochar production. The research aimed to evaluate the potential of biochar as biofuels, adsorbents, and soil amendments. Proximate, ultimate, and elemental analyses were conducted to determine their composition and caloric values. Several analytical techniques were used in the physical and chemical characterization of the biochar (SEM, FTIR, BET). The results indicated that the highest SBET values were achieved under different conditions for each biochar: 89.58 m2/g for BC-CS-700, 202.39 m2/g for BC-RH-600, and 42.45 m2/g for BC-CD-800. Additionally, all three biochars exhibited the highest caloric values at 600 °C. The results showed that 600 °C is the general optimal temperature to produce biochar from an assortment of biomass materials, considering their use for a variety of purposes. BC-CS-800 had the highest elemental carbon content at 93%, accompanied by a relative decrease in oxygen content. The van Krevelen diagram of biochar products shows that biochars derived from coconut shells and rice husks are suitable for use as fuels. Furthermore, FTIR analysis revealed the presence of oxygen-containing functional groups on the biochar surface, enhancing their pollutant adsorption capabilities. This study provides valuable insights into the scalable and environmentally sustainable production of biochar, emphasizing its role in improving soil quality, increasing energy density, and supporting sustainable agricultural practices.

Sea vessels and artificial sea‐based structures are severely affected by biofouling, i.e., the formation of deposits of living and dead marine organisms that belong to different species and range in size from unicellular bacteria to multicellular seaweed and mussels. This is a significant engineering problem since they essentially alter the geometry of the hull, increasing friction and reducing the speed of vessels, thus increasing the cost and environmental footprint of transportation. Given the scale of global transportation reaches several billion tons per year, the socioeconomic consequences of the reduction in transit speed and increased consumption of fuel continue to drive researchers and engineers to develop strategies to combat the processes of marine biofouling. Many types of antifouling paints, coatings, and materials that have been designed and tested, and in some instances used commercially, suffer from shortcomings ranging from environmental toxicity to limited efficiency and durability. In this review article, a brief overview of the traditional antifouling materials is presented and recent achievements in the design of advanced antifouling materials based on such nanomaterials as graphene, nanotubes, nanoparticles, and more complex nanostructures are discussed. These materials exhibit excellent antifouling properties and candrive a breakthrough in how marine biofouling is tackled.

“…Alternatively, more complex procedures can be used, ranging from mechanochemistry-based [74] to impregnation [75] and washing with several organic and inorganic solutions [76][77][78][79][80]. The covalent conjugation with metal-organic frameworks or with polymeric chains is also used to modulate the interfacial properties of BC [81,82]. An interesting tailoring process is represented by BC activation.…”

The development of heterogeneous catalysts is one of the pillars of modern material science. Among all supports, carbonaceous ones are the most popular due to their high surface area, limited cost, and tunable properties. Nevertheless, materials such as carbon black are produced from oil-derived sources lacking in sustainability. Pyrolytic carbon produced from biomass, known as biochar, could represent a valid solution to combine the sustainability and performance of supported catalysts. In this review, we report a comprehensive overview of the most cutting-edge applications of biochar-based catalysts, providing a reference point for both experts and newcomers. This review will provide a description of all possible applications of biochar-based catalysts, proving their sustainability for the widest range of processes.
