19. Impact of changes in climate and CO2 on the carbon-sequestration potential of vegetation under limited water availability using SEIB-DGVM version 3.02

Abstract

Documenting year-to-year variations in carbon-sequestration potential in terrestrial ecosystems is crucial for the determination of carbon dioxide (CO2) emissions. However, the magnitude, pattern and inner biomass partitioning of carbon-sequestration potential, and the effect of the changes in climate and CO2 on inner carbon stocks, remain poorly quantified. Herein, we use a spatially explicit individual based-dynamic global vegetation model to investigate the influences of the changes in climate and CO2 on the enhanced carbon-sequestration potential of vegetation. The modelling included a series of factorial simulations using the CRU dataset from 1916 to 2015. The results show that CO2 predominantly leads to a persistent and widespread increase in above-ground vegetation biomass carbon-stocks (AVBC) and below-ground vegetation biomass carbon-stocks (BVBC). Climate change appears to play a secondary role in carbon-sequestration potential. Importantly, with the mitigation of water stress, the magnitude of the above- and below-ground responses in vegetation carbon-stocks gradually increases, and the ratio between AVBC and BVBC increases to capture CO2 and sunlight. Changes in the pattern of vegetation carbon storage was linked to regional limitations in water, which directly weakens and indirectly regulates the response of potential vegetation carbon-stocks to a changing environment. Our findings differ from previous modelling evaluations of vegetation that ignored inner carbon dynamics and demonstrates that the long-term trend in increased vegetation biomass carbon-stocks is driven by CO2 fertilization and temperature effects that are controlled by water limitations.

23. S-scheme heterojunction Cu2V2O7/α-Fe2O3nanosheets with effective photocatalytic activity toward organic pollutant degradation

Abstract

Photocatalytic degradation of organic pollutants is a highly promising technology. Here, we design a novel Cu2V2O7/α-Fe2O3S-scheme heterostructure by a one-step solvothermal method, which is inexpensive, easily accessible, highly solar-light efficient, and environmentally friendly. XPS demonstrates the strong interaction between Cu2V2O7and α-Fe2O3, and the photoelectricity test verifies the significant enhancement of electrical properties by the heterostructure. DFT calculations illustrate the formation of the solid built-in electric field. The construction of S-scheme heterojunction is confirmed by differential charge density, and the catalytic mechanism is determined. The efficient degradation performance of the new heterojunction was experimentally demonstrated using methylene blue (MB) and tetracycline hydrochloride (TC) as typical organic pollutants. In the study, the β-Cu2V2O7exhibited better dye adsorption ability, proving its photocatalytic degradation potential. Meanwhile, our study provides new insights into S-scheme heterojunctions and visible light-responsive composites.
