Heterogeneous catalyst based on peroxo-niobium complexes immobilized over iron oxide for organic oxidation in water

Strengths, Weaknesses, Opportunities and Threats: Computational Studies of Mn- and Fe-Catalyzed Epoxidations

“…Finally, a significant number of articles mentions the term "surface". Although this is mostly done in the context of probing the Potential Energy Surface (PES), a significant number of sources also contain the terms "immobilized" (12 entries) or "anchored" (seven entries), denoting the growing interest in the theoretical study of novel materials with catalytic activities in which these complexes are immobilized into a nanostructured matrix [25][26][27].…”

Synthesis and application of green mixed-metal oxide nano-composite materials from solid waste for dye degradation

“…Many researchers have already reported excellent performances of various iron oxide and their composite materials in removing organic pollutants and toxic ions from water (Table 2) (Magalhaes et al, 2007;Oliveira et al, 2008;Costa et al, 2003;Baldrian et al, 2006;Yang et al, 2009;Silva et al, 2011;Pariente et al, 2008;Chun et al, 2012;Zhu et al, 2014). However, in the present study, iron oxide NCMs have been prepared first time from a solid waste.…”

Nb-doped hematite: Highly active catalyst for the oxidation of organic dyes in water

“…6a) was best material for the removal of MB dye with 75% of removal capacity. The treatment with hydrogen peroxide containing compounds has been the target of niobium work and our research group has demonstrated that the removal capacity of different colors is strongly favored [19]. In these studies it became apparent that niobium decomposes H 2 O 2 forming highly oxidizing surface groups, called "peroxo" groups.…”
