Mesoporous carbon materials have emerged as promising candidates in environmental remediation due to their high surface area, tunable pore structure, and chemical stability. This study presents a facile hydrothermal synthesis method to fabricate a series of boron-doped mesoporous carbons (B-MC) using F127 as a soft template and boric acid as the boron source. The entire process aligns with green chemistry principles, avoiding toxic solvents and complex post-treatment steps. The resulting materials exhibit uniform mesoporous structures with well-defined hexagonal ordering, confirmed by transmission electron microscopy (TEM). Notably, the B-MC-F2 sample demonstrates an exceptional specific surface area of 738 m²/g and a total pore volume of 0.74 cm³/g, indicating excellent mass transfer potential.
X-ray diffraction (XRD) analysis reveals distinct (002) and (100) peaks corresponding to graphitic carbon, while small-angle XRD confirms long-range ordered mesoporosity, especially in B-MC-F1 and B-MC-F2. Fourier-transform infrared spectroscopy (FTIR) identifies functional groups such as O–H, C–H, C–O, and characteristic B–C and BO₃ vibrations, confirming successful boron incorporation. Raman spectroscopy shows ID/IG ratios between 0.75 and 0.86, suggesting moderate defect density, which enhances catalytic activity.RAB24 Antibody Purity & Documentation X-ray photoelectron spectroscopy (XPS) further verifies that boron exists primarily in BC₃ and BCO₂/BC₂O configurations, contributing to electron-deficient active sites.CRYM Antibody Formula
The electrocatalytic performance of these materials was evaluated via cyclic voltammetry (CV) and linear sweep voltammetry (LSV) in alkaline media. B-MC-F2 exhibits a low onset potential of 0.82 V and a high H₂O₂ yield of up to 77%, demonstrating superior selectivity for the two-electron oxygen reduction reaction (2e⁻ ORR). Rotating ring-disk electrode (RRDE) measurements confirm a transfer number (n) below 2.PMID:35017526 7, validating its efficiency in H₂O₂ production. This performance is attributed to the synergistic effects of high surface area, optimal pore size (~4.05 nm), and enhanced hole conductivity due to P-type semiconductor behavior induced by boron doping.
In addition, the CO₂ capture capability of the materials was assessed under ambient conditions. B-MC-F1 achieves a record adsorption capacity of 121.34 mg/g at 303 K and atmospheric pressure, outperforming most reported B-doped mesoporous carbons. The high capacity stems from increased surface area, abundant boron content, and favorable interaction between CO₂ molecules and electron-deficient boron sites. Adsorption-desorption cycling tests show stable performance over ten cycles, confirming physical adsorption dominance and excellent reusability.
These findings highlight the multifunctional potential of boron-doped mesoporous carbons in addressing critical environmental challenges. Their dual functionality—efficient H₂O₂ generation and effective CO₂ capture—makes them ideal candidates for sustainable water treatment and carbon mitigation technologies. With a simple, scalable, and eco-friendly synthesis route, this material class holds significant promise for real-world applications in pollution control and clean energy systems.MedChemExpress (MCE) offers a wide range of high-quality research chemicals and biochemicals (novel life-science reagents, reference compounds and natural compounds) for scientific use.
