Biochar, Journal Year: 2024, Volume and Issue: 6(1)

Published: Aug. 16, 2024

Abstract Hydrothermal carbonization (HTC) stands out as an eco-friendly, cost-effective method for generating renewable carbon-based materials from biomass. The HTC process yields products such hydrochars and carbon dots (CDs), possessed of notable photocatalytic capabilities due to their unique physicochemical features. Additionally, pairing traditional photocatalysts with hydrochar derivatives elevates performance, rendering them more effective. Recent times have witnessed a surge in interest these based (HC-photocatalysts). Their appeal stems multiple attributes: impeccable adaptability visible light, adjustable properties. This review delves deep into the evolving landscape HC-photocatalysts, segmenting three distinct categories: hydrochars, hydrochar-based CDs (HC-CDs), composites (HC-composites). For each category, we dissect synthesis routes, unravel mechanisms, explore various enhancement strategies. We further traverse versatile applications, spanning environmental treatment, disinfection, energy conversion, organic synthesis. In end, spotlight prevailing challenges uncharted territories domain HC-photocatalysts. essence, this serves guide, furnishing theoretical foundation steering directions future explorations tangible implementations Graphical

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: April 2, 2025

In order to enhance the photocatalytic performance of CoFe2O4, carbon (C) was exploited modify it through developing a CoFe2O4/C heterojunction photocatalyst. nanocomposites with varying C contents were fabricated simple one-pot solvothermal approach by adjusting dosage glucose. The capabilities as-prepared evaluated reduction Cr(VI) under visible light exposure. experimental results indicated that all products had substantially greater activity than CoFe2O4/C-2 being optimal not only showed 6.7 times but also outperformed considerable number previously reported photocatalysts. Furthermore, appropriate optimization experiment parameters could further improve rate CoFe2O4/C-2. addition, exhibited superior stability. Another advantageous feature is its easy recoverability from water magnetic attraction. remarkably enhanced primarily ascribed improved separation and transfer photogenerated charges, which result p-n structure. This study offers valuable reference for synthesis application highly efficient photocatalyst treating contamination in bodies.

Land salinization has become a global issue. To mitigate this issue, the modifiers and water-soluble fertilizers have emerged as promising strategy to enhance soil nutrient content promote crop production in saline soils. In study, based on hydrothermal method for preparing corn stalks derived biochar prepared using soda saline-alkali soil. Through field microplot experiments, separate interactive effects of different concentrations them were studied, well their influence growth alfalfa Leymus chinensis The combined application can effectively increase enzyme activity, significantly reducing pH alkalinity. It was found that optimal rate 20 g/kg improver resulted 4.99% decrease 11.23% Additionally, organic matter, available P2O5, NH4+-N, NO3--N contents increased by 25.74%, 28.48%, 19.87%, 32.90%, respectively. Soil activities generally peaked at fertilizers, with sucrase showing most significant increases, 31.14% 25.52% L. chinensis. Two-way ANOVA results demonstrated interaction between fertilizer pH, Ca2+ Mg2+ content, quick-acting potassium urease biomass leaf width. Moreover, planting indicated use modifies had effect promoting cultivation Our findings provided robust theoretical groundwork improving management soils optimizing such challenging environments.
