Polymer-derived ceramics & Materials design

: [1]; © 2015

Polymer-derived ceramics (PDCs) with high temperature stability under harsh environmental conditions are important for the development of unconventional ceramic compositions with new functional properties. We design preceramic polymer precursors and explore systematically the functional properties in materials derived therefrom.

Topics

high temperature H₂ separation
micro- and mesoporous ceramics
CO₂ capture and storage
sensors for harsh conditions
photocatalysis
activation of CO₂ and CH₄
design of robust porous catalyst supports
