TL;DR: In this paper, a supra-photothermal catalyst architecture was proposed for CO2 hydrogenation using a nanoporous-silica-encapsulated nickel nanocrystal, which is active for methanation and reverse water-gas shift reactions.

TL;DR: In this article, a defect-laden indium oxide, In 2 O 3−x (OH) y, with a rod-like nanocrystal superstructure, can photocatalyze the hydrogenation of CO 2 to methanol with 50% selectivity under simulated solar irradiation.

TL;DR: Ozin et al. as mentioned in this paper showed that decorating silicon nanosheets with palladium nanoparticles can render the process catalytic, which can enable the reverse water-gas shift reaction in a catalytic cycle.

TL;DR: The conversion of solar energy to chemical energy using CO2, and how the photophysical and photochemical properties of nanostructured metal oxide photocatalysts have been engineered to efficiently incorporate light into heterogeneous gas-solid CO2 hydrogenation reactions are reviewed.

TL;DR: Various solar strategies of continually increasing technology readiness levels are compared to the commercial MeOH process, which uses a syngas feed derived from natural gas, and the viability of the most promising solar MeOH strategy in an international context is discussed.
