Synthetic organic dyes, which are resistant to biodegradation, pose a notable health risk, potentially leading cancer and respiratory infections. Researchers have addressed this concern by exploring physicochemical methods remove dyes from wastewater. A particularly promising solution involves modified biochar adsorbents, demonstrate high efficiency in dye removal. Biochar, charcoal-like material derived biomass pyrolysis, offers advantages such as low cost, eco-friendliness, reusability. Beyond its role sustainable soil remediation, proves effective removing wastewater after undergoing physical or chemical modification. Acid–base activation metal–heteroatom impregnation enhances biochar's adsorption capacity. This comprehensive review examines the attributes of biochar, common for production modification, impacts raw materials, pyrolysis temperature, heating rate residence time. It further elucidates mechanism removal assessing factors influencing efficiency, including feedstock, pH, particle size, initial concentration, dosage reaction explores challenges, opportunities, reusability regeneration treating also discusses recent advances using adsorption-based biochar. The ultimately advocates enhancing performance through post-modification.

A photoelectrochemical (PEC) biosensor composed entirely of carbon nanomaterials was synthesized to detect carbohydrate antigen 19-9 (CA 19-9). The platform integrated graphitic nitride (GCN), known for its light sensitivity, polythiophene (PTh), an organic conductive and optically active material, 1-pyrenebutyric acid N-hydroxysuccinimide (PBASE), which functions both as a biolinker conjugate CA antibody electron mediator facilitate transfer from GCN PTh. formation Schottky heterojunction between PTh reduced the bandgap 2.66 1.96 eV, enhanced photogenerated electrons cathodic photocurrent generation. improvement charge due π-π stacking pyrene group PBASE is confirmed by cyclic voltammetry (CV), impedance spectroscopy (EIS), chronoamperometry (CA) findings. highest current 1.31 μA observed combination 5 wt% with GCN/PBASE ratio 1:0.5. Besides evaluating mobility GCN/PBASE/PTh, CV, EIS, were also used evaluate sensor performance. Optimization studies revealed that 0.6 μg 1 h antigen-antibody immobilization time significantly improved response. GCN/PBASE/PTh demonstrated high sensitivity across concentration 50-1000 U/ml detection limit low 0.052 U/ml. reported working range within limits required diagnostic testing patients hepatic heart problems well post-treatment monitoring colorectal pancreatic cancer patients.

Abstract A hybrid material combining graphene‐like hexagonal boron nitride (h‐BN) and graphitic carbon (g‐C 3 N 4 ), activated by visible light, was synthesized using a straightforward pyrolysis method. The structure confirmed through various characterization techniques like XRD, SEM, TEM, etc. Evaluations rhodamine B (RhB) degradation under light revealed outstanding performance, with the photocatayst containing 0.5% h‐BN in g‐C achieving nearly complete within 60 min while pristine showed 55% similar experimental conditions rate of increased up to three times after incorporation h‐BN. This exceptional performance attributed efficient separation photoinduced charge carriers. hybrid's significant specific surface area facilitated ample surface‐active sites for pollutant adsorption degradation. Moreover, its stable appropriate bandgap contributed enhanced efficiency removal. study proposes mechanism based on these findings, marking advancement 2D/2D photocatalyst systems both energy environmental applications.
