Catalytic Ozonation over Ca2Fe2O5 for the Degradation of Quinoline in an Aqueous Solution

Shuhuan Wang et al.

Summary: The treatment of industrial wastewater with various organic compounds is crucial for controlling water pollution. The catalytic ozonation process, known for its high efficiency and ease of operation, is widely used in wastewater treatment. In this study, a Ca2Fe2O5 catalyst prepared by the sol-gel method was found to effectively remove quinoline through catalytic ozonation. The catalyst exhibited sheet micromorphology, good crystal structure, and a higher number of oxygen vacancies compared to the Fe2O3 catalyst. These oxygen vacancies promoted the decomposition of ozone molecules and the generation of active free radicals. The Ca2Fe2O5 catalyst demonstrated superior catalytic activity compared to other reported catalysts, effectively removing quinoline and other organics from aqueous solutions. The Ca2Fe2O5/O-3 system facilitated the generation of (OH)-O-center dot radicals, which inhibited the direct reaction between ozone and quinoline and the formation of NH4+-N. Additionally, the catalytic ozonation process, with the generation of (OH)-O-center dot radicals, efficiently enhanced the removal rate of chemical oxygen demand. Intermediate products in the catalytic ozonation process were studied using electrospray ionization-mass spectrometry analysis. This research offers a promising approach to develop efficient catalysts for the treatment of quinoline using catalytic ozonation.

Minerals: A missing role for enhanced biochar carbon sequestration from the thermal conversion of biomass to the application in soil

Hongyan Nan et al.

Summary: Converting biomass into biochar and amending it into soil is seen as a promising strategy for carbon sequestration and climate change mitigation. Minerals play a crucial role in regulating the carbon retention and stability of biochar, both during the pyrolysis process and in soil. By adding certain minerals, such as P, Si, Ca, Mg, and K, the carbon retention in biochar can be significantly increased. Soil minerals also interact with biochar-carbon, preventing its disintegration and oxidation. Future research should focus on systematically evaluating the role of minerals in the biochar carbon cycle process.
