There is provided an improved electrically heated accordion folded corrugated thin metal catalytic converter for hydrocarbon or alcohol fueled engine exhaust, particularly internal combustion engine exhaust, having a simplified construction and characterized in that the entire corrugated thin metal monolith, or monoliths, serves as a resistance heater to bring the catalyst up to optimum operating temperature quickly and thereby reduce the escape of pollutants into the atmosphere upon start-up, and which does not depend upon conduction as a mdoe of heat transfer to achieve such temperature.
