<p>An electro-catalytic honeycomb for controlling exhaust emissions, which adopts to purify a lean-burn exhaust, comprises a honeycomb structural body (10), a solid-oxide layer (20) and a cathode layer (30). The honeycomb structural body (10) includes an anode (11), a plurality of gas channels (12), and a shell (13). The anode (11) is formed as a backbone, the gas channels (12) are formed inside the backbone for passing the exhaust, and the shell (13) covers an outer surface (111) of the anode (11). The solid-oxide layer (20) is adhered to an inner surface (112) of the anode (11) and connects the shell (13) so as to encapsulate the anode (11). The cathode layer (30) is adhered to a tube wall (21) of the solid-oxide layer (20) and has an oxidizing environment. The anode (11) has a reducing environment. The reducing and the oxidizing environment facilitate an electromotive force to occur between the anode (11) and the cathode layer (30) to promote a decomposition of nitrogen oxides of the exhaust into nitrogen and oxygen.</p> |
