This study examines corn stalk biochar (CSB)-enhanced mortar as an innovative material for carbon capture and CO2 sequestration. CSB, a renewable agricultural byproduct, was incorporated into cement at varying concentrations (2.5% to 75%), its effects on the mortar’s physicochemical properties, ability support algal growth, absorption capacity of algae were analyzed. Characterization CSB showed high content (62.3%), significant porosity, large surface area (680.3 m2 g−1), making it ideal gas capture. At low (2.5%), slightly improved compressive strength density. However, higher levels (5% 75%) led reductions (p < 0.05) in density, while water increased. sequestration monitored from growth studies revealed that both Chlorella sp. (TISTR 8262) Scenedesmus 9384) thrived CSB-enhanced mortars. 75% concentration, achieved 24.2-fold increase biomass by day 12, outperforming sp., which 26.6-fold increase. also with biochar. Mortars 86% ratio without algae, adding boosted this nearly 100%, highlighting synergistic effect photosynthesis.

Electrocatalytic CO₂ Reduction Empowered by 2D Hexagonal Transition Metal Borides

Advanced Science, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

Abstract Electrocatalysis holds immense promise for producing high‐value chemicals and fuels through the carbon dioxide reduction reaction (CO 2 RR), advancing global sustainability neutrality. However, conventional electrocatalysts based on transition metals are often limited by significant overpotentials. Since discovery of first hexagonal MAB ( h ‐MAB) phase, Ti InB , its 2D derivative in 2019, metal borides ‐MBenes) have emerged as promising candidates various electrochemical applications. This study presents theoretical investigation into CO RR catalytic properties pristine ‐MBenes ‐MB) their ─O ‐MBO) ─OH ‐MBOH) terminated counterparts, focusing such Sc, Ti, V, Zr, Nb, Hf, Ta. These results reveal while ‐MB ‐MBO exhibit poor performance due to overly strong or weak interactions with ‐MBOH shows great promise. Notably, ScBOH, TiBOH, ZrBOH display exceptionally low limiting potentials U L ) −0.46, −0.53, −0.64 respectively. findings uncover unique role tuning electronic ‐MBenes, thereby optimizing intermediate adsorption, which prevents excessive binding enhances efficiency. research offers valuable insights potential highly efficient catalysts, underscoring versatility prospects

Estimation of Coastal Wetland Vegetation Aboveground Biomass by Integrating UAV and Satellite Remote Sensing Data

Remote Sensing, Год журнала: 2024, Номер 16(15), С. 2760 - 2760

Aboveground biomass (AGB) serves as a crucial indicator of the carbon sequestration capacity coastal wetland ecosystems. Conducting extensive field surveys in wetlands is both time-consuming and labor-intensive. Unmanned aerial vehicles (UAVs) satellite remote sensing have been widely utilized to estimate regional AGB. However, mixed pixel effects hinder precise estimation AGB, while high-spatial resolution UAVs face challenges estimating large-scale To fill this gap, study proposed an integrated approach for AGB using sampling, UAV, Sentinel-2 data. Firstly, based on multispectral data from vegetation indices were computed matched with sampling develop Field–UAV model, yielding results at UAV scale (1 m). Subsequently, these upscaled (10 Vegetation calculated establish UAV–Satellite enabling over large areas. Our findings revealed model achieved R2 value 0.58 0.74 scale, significantly outperforming direct modeling (R2 = −0.04).
