Carbon dioxide (CO
2
) hydrogenation to liquid fuels including
gasoline, jet fuel, diesel, methanol, ethanol, and other higher alcohols
via heterogeneous catalysis, using renewable energy, not only effectively
alleviates environmental problems caused by massive CO
2
emissions, but also reduces our excessive dependence on fossil fuels.
In this Outlook, we review the latest development in the design of
novel and very promising heterogeneous catalysts for direct CO
2
hydrogenation to methanol, liquid hydrocarbons, and higher
alcohols. Compared with methanol production, the synthesis of products
with two or more carbons (C
2+
) faces greater challenges.
Highly efficient synthesis of C
2+
products from CO
2
hydrogenation can be achieved by a reaction coupling strategy
that first converts CO
2
to carbon monoxide or methanol
and then conducts a C–C coupling reaction over a bifunctional/multifunctional
catalyst. Apart from the catalytic performance, unique catalyst design
ideas, and structure–performance relationship, we also discuss
current challenges in catalyst development and perspectives for industrial
applications.
