The Diverse Modes of Oxygen Reactivity in Life & Chemistry

Abstract

Oxygen is a molecule of utmost importance in our lives. Beside its vital role for the respiration and sustaining of organisms, oxygen is involved in numerous chemical and physical processes. Upon combination of the different forms of molecular oxygen species with various activation modes, substrates, and reaction conditions an extremely wide chemical space can be covered that enables rich applications of diverse oxygenation processes. This Review provides an instructive overview of the individual properties and reactivities of oxygen species and illustrates their importance in nature, everyday life, and in the context of chemical synthesis.

Toward High Performance Mixed Ionic and Electronic Conducting Perovskite-Based Oxygen Permeable Membranes: An Overview of Strategies and Rationales

“…For example, Kiebach et al discussed the research progress of two-phase OPMs in detail. 4 Chen et al summarized the advanced research level, application status, and future development of MIEC membranes. 52 However, there has been no recent review of modification strategies to improve the membrane performance.…”

“…Oxygen serves as an essential part in the quality of human life and health, economic development, medical treatment, fire protection, and the chemical industry. − Furthermore, oxygen is tightly linked to carbon neutrality in carbon capture and storage (CCS) technology. − The biggest challenge involving carbon capture in oxygen-enriched combustion technology is the high investment in oxygen production technology. At present, there are three mature technologies for oxygen production: pressure swing adsorption, low-temperature distillation, and polymer membrane separation. , However, these technologies are all faced with two conflicting dilemmas that exist in oxygen production.…”

“…The MIEC materials can transport ions and electrons at the same time without an external circuit . To balance the electroneutrality of the membrane material, the migration direction of ions and electrons is reversed.…”

“…23−27 The MIEC materials can transport ions and electrons at the same time without an external circuit. 4 To balance the electroneutrality of the membrane material, the migration direction of ions and electrons is reversed. Perovskite materials have favorable ionic and electronic conductivities, so they have a higher oxygen flux than other materials, such as fluorites and brownmillerites.…”

Oxidation Kinetics of Neat Methyl Oleate and as a Blend with Solketal

“…In addition, polar aging products exhibit enhancement of mutagenic emissions [6]. The process of oxygen incorporation occurs through peroxidation, known as lipid peroxidation [7], which also plays an important role on vegetable oils in food science [8,9]. In general, the initiation…”
