SrFeO3 peculiarities and exploitation in decontamination processes and environmentally-friendly energy applications

Investigation of AFeO3 (A=Ba, Sr) Perovskites for the Oxidative Dehydrogenation of Light Alkanes under Chemical Looping Conditions

“…Additionally, SrFeO 3 has low toxicity and does not contain expensive rare earth elements and precious metals, making it attractive for applications in environmental remediation and sustainable energy supply. [22] Over two decades ago, bare SrFeO 3 was discovered as a potential ethane ODH catalyst, exhibiting moderate ethylene selectivity (41 %) and yield (34 %) in a feed mixture of air and ethane at 650 °C. [23] However, only a few attempts have been made since then to improve the ODH performance of SrFeO 3 .…”

The ex situ exsolved Ni–Ru alloy from nickel–ruthenium co-doped SrFeO3−δ perovskite as a potential catalyst for CC and CO hydrogenation

“…Iron cations in SrFeO 3−d have a mixed valence state ranging from +3 to +4 with respect to oxygen non-stoichiometry and favour several structural arrangements ranging from cubic, tetragonal, to orthorhombic brownmillerite phases. 12,13 The doping of different transition metals on the B sites of SrFeO 3−d , stabilises the perovskite structure and potentially improves the redox properties of the materials. Several studies have been conducted in the literature on the impact of different dopants on SrFeO 3−d , including Mo, Ti, Cu, Zr, Cr, W, and Nb.…”

An Overview of Environmental Catalysis Mediated by Hydrogen Peroxide

“…The oxidation processes exploiting H2O2 and the derived ROS are the focus of the present review. Many different treatments have been proposed [11,[15][16][17][18], also in a variety of combinations and with different triggering sources (ultrasounds, UV/vis light, heat and electrochemical energy) [7,15,[19][20][21][22][23][24], as summarized in Figure 1. In Figure 1, the methods that are mainly recognized to be capable of inducing an in situ generation of ROS [17,[25][26][27] have been underlined since the use of such methods can overcome the problems related to high costs and excessive consumption of hydrogen peroxide, as well as avoid the hazards associated with its transport, handling, and storage in significant quantities [25,27,28].…”
