A perspective on bridging academic research and advanced testing on a path towards pilot plant implementation: A case study of integrating CO2 capture and catalytic conversion with dual function materials

The term “dual function material” (DFM) was coined by our research group for codispersed catalysts (e.g., Ru) and alkaline sorbents on the same high-surface-area carrier. These materials allow for combined CO2 capture and catalytic conversion, thus their dual functional nature. Herein, we report an additional, unexpected function; combining Ru with specific adsorbents and carriers substantially enhances CO2 capture capacity. Investigation of several Ru + sorbent/carrier formulations shows that the enhanceme

Mechanistic assessment of dual function materials, composed of Ru-Ni, Na2O/Al2O3 and Pt-Ni, Na2O/Al2O3, for CO2 capture and methanation by in-situ DRIFTS

A series of CeO2-MnOx/Nb2O5-x catalysts, with monoclinic Nb2O5-x (pre-calcined at 1025 °C) as the carrier, were synthesized and evaluated for catalytic oxidation of C3H8 and CO. The addition of CeO2 greatly reduces the MnOx particle size, increases the dispersion of MnOx, and results in the formation of a Ce-Mn solid solution as well as a new Nb-Mn-Ce based phase, which leads to the upgrading of redox properties and enhances the ability for binding intermediates during reaction, contributing to the enhanced
