The present disclosure provides a microwave-assisted carbon template method for preparing supported nano metal-oxides or nano metals. The method includes mixing a carbohydrate, urea, and a precursor of an oxide support with a metal salt in a container, adding a certain amount of water, and completely dissolving the solid chemicals through ultrasonic stirring to form a homogeneous solution. The method also includes performing microwave treatment on the obtained solution for approximately 0.1 minute to 60 minutes with a microwave heating power in a range of approximately 100 W to 50 kW to dehydrate and carbonize the carbohydrate and thus form a dark brown solid. The method further includes performing heat treatment on the dark brown solid at a temperature in a range of approximately 200° C. to 1100° C. in an air atmosphere for approximately 0.5 hour to 24 hours to obtain a metal-oxide supported by a porous oxide support.
