Porous-structured Cu 2 O/TiO 2 nanojunction material is successfully fabricated by a facile method via loading Cu 2 O nanoparticles on the network of a porous TiO 2 substrate. The developed Cu 2 O/TiO 2 nanojunction material has a size of several nanometers, in which the p-type Cu 2 O and n-type TiO 2 nanoparticles are closely contacted with each other. The well designed nanojunction structure is beneficial for the charge separation in the photocatalytic reaction. Meanwhile, the porous structure of the Cu 2 O/TiO 2 nanojunction can facilitate the CO 2 adsorption and offer more reaction active sites. Most importantly, the gas-phase CO 2 photoreduction tests reveal that our developed porous-structured Cu 2 O/TiO 2 nanojunction material exhibits marked photocatalytic activity in the CH 4 evolution, about 12, 9, and 7.5 times higher than the ...
