Abstract: The present invention relates to a porous metal oxide-carbon composite having an impregnated photoactive metal oxide, a manufacturing method thereof, and a photocatalyst including the same and, more specifically, to a porous metal oxide-carbon composite having titanium dioxide and a post-transition metal impregnated with carbon-based media. The metal oxide-carbon composite according to the present invention can exhibit excellent photocatalytic activities in the range of visible light (λ>=400 nm) as well as in the range of ultraviolet rays and facilitates separation and recovery thereof after use because the particle size thereof is on a scale of approximately hundreds of micrometers. Loss induced by collisions between particles in a fluid state can be prevented, thereby facilitating application of the metal oxide-carbon composite to a commercial process because one particle of the metal oxide-carbon composite can resist the strength of 5 to 15 kg-f/a unit. Besides, the metal oxide-carbon composite according to the present invention can be applied to various fields such as water treatment and air purification industry, thereby being capable of being applied to commercial processes using a photocatalyst because the metal oxide-carbon composite exhibits photocatalytic activities in a wide wavelength range.
