High pressure high temperature carbon dioxide

Molecular carbon dioxide at high pressure and high temperature

High-pressure polymeric phases of carbon dioxide.

Understanding the structural transformations of solid CO(2) from a molecular solid characterized by weak intermolecular bonding to a 3-dimensional network solid at high pressure has challenged researchers for the past decade. We employ the recently developed metadynamics method combined with ab initio calculations to provide fundamental insight into recent experimental reports on carbon dioxide...

Melting curve and fluid equation of state of carbon dioxide at high pressure and high temperature.

The melting curve and fluid equation of state of carbon dioxide have been determined under high pressure in a resistively heated diamond anvil cell. The melting line was determined from room temperature up to 11.1+/-0.1 GPa and 800+/-5 K by visual observation of the solid-fluid equilibrium and in situ measurements of pressure and temperature. Raman spectroscopy was used to identify the solid ph...

Spatially confined catalysis-enhanced high-temperature carbon dioxide electrolysis.

In this study, a potential ilmenite cathode material Ni0.9TiO3 is designed for efficient CO2 electrolysis in an oxide-ion-conducting solid-oxide electrolyzer. Spatially confined catalysis has been successfully achieved to substantially improve cathode activity by in situ growth of catalytically active nickel nanoparticles on a ceramic skeleton. The combined analysis of XRD, SEM, EDS, XPS, TGA a...
