Electronic structure manipulation via composition tuning for the development of highly conductive and acid-stable oxides

Abstract

Exploring materials that simultaneously possess high conductivity and electrochemical stability is critical for various energy-conversion applications. In this study, our combined computations and experiments suggest the Mg–Ti–O chemical space for...

Inverse Consequences of the SnO2 Protection Layers on Pt/C Catalysts in Proton-Exchange Membrane Fuel Cells

“…Similarly, we previously introduced Mg 1−x Ti 2+x O 5−y ternary compounds, aiming to simultaneously achieve high conductivity and strong acidic stability. 16 A high synthesis temperature of 1500 °C was selected to further improve the conductivity by reducing the oxidation state of Ti in the structure. However, this approach presents challenges in achieving a large surface area comparable to that of commercial carbonaceous supports because of the high-temperature synthesis process required.…”

“…TiN offers high electrical conductivity while TiO 2 provides good corrosion resistance. Similarly, we previously introduced Mg 1– x Ti 2+ x O 5– y ternary compounds, aiming to simultaneously achieve high conductivity and strong acidic stability . A high synthesis temperature of 1500 °C was selected to further improve the conductivity by reducing the oxidation state of Ti in the structure.…”

Efficiently predicting and synthesizing intrinsic highly fire-safe polycarbonates with processability

“…Unfortunately, this paradigm is time consuming and less efficient. [27][28][29][30][31] The material genome approach (MGA) based on data-computation-experiment integration, is a novel paradigm for rational design of novel materials in a more efficient and economical manner. [31][32][33][34] In recent years, the MGA has been successfully used in the design of novel materials such as energetic materials, 35 superalloys, 36 polymers 37 and metal-organic frameworks.…”
