How does anodization time affect morphological and photocatalytic properties of iron oxide nanostructures?

引用

Journal of Materials Science & Technology 2020年第3期38卷 159-169页

作者： Bianca Lucas-Granados Rita Sánchez-Tovar Ramón MFernández-Domene josémaría Estívalis-martínez joséGarcía-Antón Ingeniería Electroquímica y Corrosión(IEC).Instituto Universitario de Seguridad Industrial Radiofísica y Medioambiental(ISIRYM)Universitat Politècnica de ValènciaCamino de Vera s/n46022ValenciaSpain Departmento de Ingeniería Química Universitat de ValènciaAv de les Universitatss/n46100 BurjassotSpain

Iron oxide nanostructures are promising materials to be used as photocatalysts in different photoelectrochemical applications. There are different techniques in order to synthesize these nanostructures, but one of the most inexpensive and simple method is electrochemical anodization. This method can lead to different nanostructures by controlling its parameters. Anodization time is one of the most critical parameters since it considerably affects the properties of the obtained nanostructures. In this work, different anodization times(5, 10, 15, 30 and 60 min) were studied. The resulting nanotubes were characterized by field emission scanning electron microscopy, Raman laser confocal microscopy, water splitting measurements, Mott-Schottky analysis and electrochemical impedance spectroscopy, in order to test their viability for being used as photocatalysts in photoelectrochemical applications. Results showed that the best photocurrent density values in water splitting tests(0.263 m A m-2) were achieved for the sample anodized for 10 min under hydrodynamic conditions.

Driving factors of tree biomass and soil carbon pool in xerophytic forests of northeastern Argentina

Background The conversion of forests into agricultural lands can be a threat because the forests carbon stored could be a source of emissions. The capacity to improve the predictions on the consequences of land use change depends on the identification of factors that influence carbon pools. We investigated the key driving factors of tree biomass and soil carbon pools in xerophytic forests in northeastern Argentina. Based on analyses of forest structure variables and abiotic factors (topography and soil properties) from 18 mature forests, we evaluated carbon pools using uniand multivariate (redundancy analysis) methods. Results The total carbon pool was estimated at 102.4 ± 24.0 Mg ha−1. Soil organic carbon storage is the single largest carbon pool relative to tree biomass, representing 73.1% of total carbon. Tree canopy cover and basal area were positively correlated with biomass carbon pool (r = 0.77 and r = 0.73, p < 0.001, respectively), proving to be significant drivers of carbon storage in this compartment. Slope, soil clay content and cation-exchange capacity had a better explanation for the variability in soil carbon pools, and all showed significant positive correlations with soil carbon pools (r = 0.64, 0.60 and 0.50;p < 0.05, respectively). The vertisols showed a 27.8% higher soil carbon stock than alfisols. Conclusions The relevance of our study stems from a dearth of information on carbon pools and their drivers in xerophytic forests, and in particular, the importance of this ecosystems’ type for Argentina, because they cover 81.9% of native forest area. Basal area and tree canopy cover exert a strong effect on the carbon pool in tree biomass but not in the soil. The results suggests that there is a potentially major SOC accumulation in forests located in slightly sloping areas and soils with higher topsoil clay content, such as vertisols. This could provide an important reference for implementing forestry carbon sink projects.
