Converting carbon dioxide (CO2) into value-added
fuels
or chemicals through photothermal catalytic CO2 hydrogenation
is a promising approach to alleviate the energy shortage and global
warming. Understanding the nanostructured material strategies in the
photothermal catalytic CO2 hydrogenation process is vital
for designing photothermal devices and catalysts and maximizing the
photothermal CO2 hydrogenation performance. In this Perspective,
we first describe several essential nanomaterial design concepts to
enhance sunlight absorption and utilization in photothermal CO2 hydrogenation. Subsequently, we review the latest progress
in photothermal CO2 hydrogenation into C1 (e.g.,
CO, CH4, and CH3OH) and multicarbon hydrocarbon
(C2+) products. Finally, the relevant challenges and opportunities
in this exciting research realm are discussed. This perspective provides
a comprehensive understanding for the light–heat synergy over
nanomaterials and instruction for rational photothermal catalyst design
for CO2 utilization.
The catalytic oxidation of chlorinated volatile organic compounds (CVOCs) faces the stringent constrain of high reaction temperature for large-scale application. In this work, hollow spherical Cu0.15Mn0.15Ce0.7Ox was synthesized by carbon...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
