Enhanced Visible Light Photocatalytic Hydrogenation of CO2 into Methane over a Pd/Ce-TiO2 Nanocomposition

A series of Ce-doped TiO 2 nanoparticles were prepared by a sol–gel process and characterized by XRD, SEM, TEM, EDX mapping, UV–vis DRS, Raman spectroscopy, N 2 adsorption–desorption, PL spectra, CO 2 -TPD, and XPS. It is found that Ce ions can enter the lattice matrix of TiO 2 and occupy of Ti site... View More
