This review paper delineates an overview of recent developments on photocatalytic processes for the photoreduction of CO 2

into C1 solar fuels including methanol and methane. The effi ciency of the novel processes reported is compared in terms of

the yields of C1 fuels. Brief introduction on synthetic protocols of the cited photocatalysts employed for the photoreduction

of CO 2 into C1 fuels is succinctly discoursed in this work. Furthermore, an additional review section is also included for

summarizing the recently published ideas of diff erent confi gurations of photocatalytic membrane processes utilized for the

separation of CO 2 converted C1 products from the reaction solvent. It was concluded that there is still substantial room of

improvement for both newly developed photocatalytic systems and membrane processes in terms of C1 yield and the fuel

separation effi ciency, respectively. Despite its potential as a promising green candidate used for carbon capture and utilization,

additional studies are still necessary prior to its scalable application in industry. These studies should take a deep dive into

the optimization of both photocatalytic and membrane separation processes, largely by development of novel photocatalytic

systems that are highly effi cient in CO 2 conversion and membrane systems that are selective toward desired fuel products.
