Abstract
Methods have been developed to form catalysts having active metals disposed on a carbon nanotube coated porous substrate. Catalysts and reactions over nanotube-containing catalysts are also disclosed. Results are presented showing enhanced performance resulting from use of the inventive catalyst. Mesoporous oxide layers can be utilized to improve catalyst properties.
Claims29
A method of conducting a catalyzed chemical reaction, comprising:
- passing at least one reactant into an engineered catalyst wherein the catalyst comprises a support material having through-porosity;
- a layer comprising carbon nanotubes disposed over the support material;
