LED-driven controlled deposition of Ni onto TiO₂ for visible-light expanded conversion of carbon dioxide into C₁–C₂ alkanes

Abstract

Photocatalytic gas-phase hydrogenation of CO2 into alkanes was achieved over TiO2-supported Ni nanoparticles under LED irradiation at 365 nm, 460 nm and white light. Photocatalysts were prepared using the photo-assisted...

Design and Development of Photocatalytic Systems for Reduction of CO2 into Valuable Chemicals and Fuels

“…Sanz-Marco et al [71], synthesized Ni/TiO 2 by photo-assisted deposition of Ni salts under LED irradiation at 365 nm onto TiO 2 P25 nanoparticles in CH 3 OH as a hole scavenger. In this way, the surface of TiO 2 is coated with a 2 nm thick layer and approximately 2 mass% of Ni particles.…”

A review on TiO2−x-based materials for photocatalytic CO2 reduction

“…It has already been demonstrated that the metal-reduced TiO 2 94 with high electron concentration and excellent electron mobility could be used for efficient photocatalytic reduction of CO 2 . Sanz-Marco et al 95 investigated the generation of structural defects in the TiO 2 framework by correlative characterization, and further elucidated the coexistence of strong metal–support interaction between divalent Ni and TiO 2− x . The non- in situ thermal pre-activation of Ni–TiO 2− x strongly promoted the photo-driven/photo-assisted/LED-driven conversion of CO 2 hydrogenation to CO, CH 4 and C 2 H 6 .…”
