Immobilizing Polysulfide via Multiple Active Sites in W18O49 for Li-S batteries by Oxygen Vacancy Engineering

Superfine SnO2–x Particles Embedded in a Porous Carbon Matrix as a Separator-Modifying Material for High-Performance Lithium Sulfur Batteries

“…SnO 2−x /PC has a distinct signal with a g value of 2.002. 36 All these results indicate the highly anoxic characteristic of SnO 2−x in SnO 2−x /PC. The SEM images of PC and SnO 2−x /PC are shown in Figure 5a−d.…”

“…Figure 9f shows the EIS plots of the batteries before cycling, which is composed of the semicircle in the high-frequency region and the straight line in the low-frequency region. 36 Figure 9g shows the EIS plots of the batteries after 50 cycles. Unlike Figure 9f, two semicircles can be observed in Figure 9g.…”

High electrocatalytic activity of Pt on porous Nb-doped TiO2nanoparticles prepared by aerosol-assisted self-assembly

“… 33 Nb-TiO 2 afforded a characteristic EPR signal with high intensity at a g value of 2.003, corresponding to bridging oxygen vacancies (Ti 4+ –O–O˙). 34 The EPR signal was slightly enhanced upon niobium incorporation.…”

Reactive species specific RhB assisted collective photocatalytic degradation of tetracycline antibiotics with triple-layer Aurivillius perovskites

“…Similar suppression of the EPR signal is reported due to anchoring of surface species by oxygen vacancies. 76 When the catalyst suspended in RhB was exposed to light, an additional signal at g = 1.975 appeared in the EPR spectra (Fig. S16 ESI †), which is attributed to the presence of Ti 3+ species.…”
