And the article was included in Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) in 2022.Recommanded Product: 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide This article mentions the following:
In order to obtain a robust, durable and efficient heterogeneous catalyst, macroscopic monolithic Zn-doped 濞?Fe2O3/graphene aerogel (GA) hybrid architecture with integrated morphol. and hierarchically porous structure were controllably synthesized via a facile in-situ hydrothermal method and then used as persulfate (PS) activator for sulfamonomethoxine (SMM) wastewater purification Several key reaction parameters including the initial SMM concentration, reaction temperature, coexisting inorganic anions and SMM in real natural water samples had different influence on the SMM removal efficiency. The catalytic efficiency of Zn-doped 濞?Fe2O3/GA with the molar ratio of Fe/Zn = 2:1.5 was about 66%, 62%, 66% and 11%闂?3% higher than that of GA, 濞?Fe2O3/GA, Zn/GA and other Fe/Zn molar ratio. The improved activity of Fe/Zn = 2:1.5 benefits from the synergistic effects of the sp2 hybridized carbon and porous framework, as well as the surface oxygenic functional groups, which accelerate the pollutant/oxidant dispersion and electron transfer. ESR results indicate that 閻犺櫣鏋綡, 1O2 and SO閻?sup>-4 radicals account for the catalytic degradation of SMM and the activation of PS in present system is different from conventional homogeneous systems, and speculate mechanism was proposed based on the obtained data. In the experiment, the researchers used many compounds, for example, 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3Recommanded Product: 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide).
4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3) belongs to pyrimidine derivatives. The pyrimidine ring system has wide occurrence in nature as substituted and ring fused compounds and derivatives. As nucleotides in DNA and RNA, pyrimidine nucleotide derivatives have a wide range of biological applications. For example, pyrimidine derivatives are useful in DNA repair studies involving cancer and epigenetics.Recommanded Product: 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide
