Electronic Activation At Oxide Hetero-structure At Elevated Temperatures – Source Of Markedly Accelerated Oxygen Reduction Kinetics
To understand ultra-fast oxygen reduction reaction kinetics near La0.8Sr0.2CoO3/(La0.5Sr0.5)2CoO4 (LSC113/214) interface, a combination of in-situ scanning tunneling spectroscopy and focused ion beam milling was used to study the local electronic structure near LSC113/214 interface at elevated temperature and in oxygen. The electronic activation of LSC214 by the coupling with LSC113, concurrent...
متن کاملIsothermal Redox Kinetics of Co3O4-Fe2O3 Nano-Composite as a Thermochemical Heat Storage Material
Isothermal redox kinetics of as-received Co3O4 (AC), 1 h ball milled Co3O4 (BC), and 1 h ball milled Co3O4-15wt.% Fe2O3 (BCF) was investigated at various temperatures (1130, 1100, 1070, and 1040 °C for reduction and 830, 860, and 890°C for re-oxidation) by thermogravimetric method. It was found that mechanic...
متن کاملبهبود پایداری حرارتی و مطالعه رفتار سینتیک تخریب ماده منفجره پلاستیکی C4 در حضور آنتی‌اکسیدان ایرگانوکس 1010
C4 composition is a conventional military explosive formulation based on cyclotrimethylenetrinitramine explosive (RDX) and polyisobutylene binder (PIB), which some environmental factors such as thermal and oxygen lead to change in its color and physical characteristics. Using anti-oxidant to reduce the impact of environmental factors and increasing the stability of materials...
متن کاملIntroducing Pt/ZnO as a new non carbon substrate electro catalyst for oxygen reduction reaction at low temperature acidic fuel cells
Gas diffusion electrode was used for providing better conditions in fuel cell systems for oxygen reduction reaction (ORR). Because the slow kinetics of the oxygen reduction reaction at the proton exchange membrane fuel cell cathode restricts fuel cell efficiency. To this end, researchers have used platinum-coated carbon. In the present study, due to the reduction of carbon corrosion, Zinc oxide...
