This work describes the use of TiO_(2)nanotubes-based electrodes(TNT)modified with Cu_(2)O nanostructures and gold nanoparticles for the photoelectroreduction of CO_(2)to produce v.lue-added compounds.A thin layer of polydopamine was used as both an adherent agent and an electron transfer mediator,due to itsπ-conjugated electron *** highest production yield was achiev.d using a TNT@PDA/Nc/Au40%electrode,with Faradaic efficiencies of 47.4%(110.5μm cm^(-2))and 27.8%(50.4μm cm^(-2))for methanol and methane,*** performance of the photoelectrodes was shown to be Cu_(2)O facet-dependent,with cubic structures leading to greater conv.rsion of CO_(2)to methanol(43%)and methane(27%),compared to the octahedral morphology,while a higher percentage of metallic gold on the nanostructured Cu_(2)O surface was mainly important for *** functional theory(DFT)calculations supported these findings,attributing the superior photoelectrocatalytic performance of the TNT@PDA/Nc/Au40%electrode for CH4generation to the formation of an OCH3intermediate bonded to Au *** using isotope-labeling and analysis by gas chromatograph-mass(GC-mS)demonstrated that13CO_(2)was the source for photoelectrocatalytic generation of13CH3OH and13CH313CH2OH.
