Photo-Driven Reduction of Carbon Dioxide: A Sustainable Approach Towards Achieving Carbon Neutrality Goal

Abstract

The photo-driven reduction of carbon dioxide (CO2) into green and valuable solar fuels could be a promising solution to simultaneously address energy- and environmental-related problems. This approach could play an integral role in achieving a sustainable energy economy by closing the carbon cycle and allowing the storage and transportation of intermittent solar energy within the chemical bonds of hydrocarbon molecules. This Perspective discusses the latest technological advancements in photo-driven CO2 conversion via various pathways, namely photocatalysis, photoelectrocatalysis and photovoltaic-integrated systems. In addition to providing an outlook on unresolved issues concerning the said technologies, this Perspective also spotlights new trends and strategies in the structural engineering of materials to meet the demands for prominent CO2 photoreduction activity as well as spearhead the ground-breaking advances in the field that lead to the translation of CO2 photo-driven technologies from the laboratory to industrial-scale applications.

Photocatalytic CO2 Conversion Using Metal-Containing Coordination Polymers and Networks: Recent Developments in Material Design and Mechanistic Details

“…The combination of metal and polymer moieties merges the advantage of both materials: Metal centers build up the functional core as redox-active species, whereas polymeric materials are able to optimize the catalyst performance while acting as stabilizing structures due to their feature of being tunable. Especially for carbon dioxide conversion, metal-containing polymers can support photocatalytic [ 11 , 12 , 13 , 14 , 15 ], electrocatalytic [ 16 , 17 , 18 , 19 , 20 ], photo-electrocatalytic [ 13 , 15 , 21 , 22 , 23 ] or thermochemical [ 24 ] reduction reactions.…”

“…Simply avoiding fossil fuels might not be possible in all instances.CO 2 conversion to value-added chemicals (CO, CH 3 OH and derivatives) is a proactive approach to address both the issue of global energy demands and global warming. [2][3][4] CO 2 can be reduced to valuable chemical fuels in the presence of light using a photocatalyst, thus can help to get rid of the conundrum of fossil fuels, and reduction of greenhouse gases. [5][6][7] But the need of highly efficient, long term CO 2 reduction durable photocatalyst is still an unresolved challenge for the researchers.…”
