Photocatalytic carbon
dioxide reduction (PCCR) for methanol synthesis
(CH3OH) targeting renewable energy resources is an attractive
way to create a sustainable environment and also balance the carbon-neutral
series. The application of PCCR to methanol enables the generation
of solar energy while reducing CO2, killing two birds with
one stone in terms of energy and the environment. In recent years,
research on CO2utilization has focused on hydrogenation
of CO2to methanol due to global warming. This article
mainly focuses on selective carbonaceous materials such as graphene,
mesoporous carbon, and carbon nanotubes (CNTs) as catalysts for heterogeneous
photocatalytic CO2reduction to methanol. In addition,
special emphasis will be placed on the state of the art of PCCR catalysts
as this type of research will be of great benefit for further development
in this field. The main features of the reaction kinetics, techno-economic
study, and current technological developments in PCCR are covered
in detail.
