Electrically Conductive Honeycomb Monolith of Nanolaminated Ti3AlC2: Preparation and Characterization

Nanolaminated Ti3AlC2 honeycomb monolith with parallel and uniform holes has been prepared through a facile extrusion route by using Ti3AlC2 powder as the main raw material. The fabricated honeycomb monolith has high compressive strength of 133 ± 11 and 59 ± 9 MPa, along and perpendicular to the extrusion direction, respectively. It also has good electrical conductivity, and excellent match of thermal expansion coefficient with the washcoat material of γ-Al2O3. These combined properties endow the honeycomb monolith a promising candidate as catalysis substrate for cleaning vehicle exhaust.
