“…Interestingly, in addition to the production CO, H 2 O was obtained as the by-product and no H 2 , instead of reductive disproportionation of CO to CO/CO 3 2− under aprotic conditions. [55][56][57] The anodic degradation of the acetonitrile electrolyte was suggested to be the proton mediator responsible for water production; through computational methods, the terminal proton source that enables the CO bond cleavage, was identified to be the reductive transformation of cyclopentadione to hydroxycyclopentadienyl.…”

provides a promising alternative to hydrocarbon sources for petrochemical feedstock. Thanks to the electrochemical nature of the CO 2 conversion to fuels and chemicals, the electrical energy invested to convert CO 2 in the form of a chemical fuel can be stored and redistributed using established supply chains for future use. Additionally, the integration of renewable energy systems (green electricity) into the grid can potentially create a carbon neutral energy cycle, and when driven by solar energy, offers a completely renewable energy cycle or negative carbon technology. Converting CO 2 electrochemically into compounds with high energy densities, such as alcohols (methanol, ethanol), formates, and CO, represents a form of energy storage and is also adaptable to demand response or energy arbitrage technologies. [3][4][5][6][7] The recoverable energy density of the chemicals that can be converted from CO 2 is substantially higher than most battery technologies.Given CO 2 electroreduction's immense economic and environmental potential, it has been the subject of much research activity over the past decades. [8][9][10][11] One of the greatest challenges of reducing CO 2 in an electrochemical cell is overcoming the immense energy barrier required to do so; the single electron reduction of CO 2 to CO 2 −˙, a common step in many CO 2 reduction mechanisms, requires an applied potential of −1.97 V measured versus standard hydrogen electrode (SHE). To alleviate this problem, many catalytic cathodes have been developed to avoid this intermediate and to reroute the reduction mechanism through alternate pathways requiring much lower applied potentials (a necessity if CO 2 electroreduction is to be implemented at industrial scale). [12][13][14] However, despite the low potentials offered by catalytic electrodes, the cost of electrodes is not always viable when upscaled to industrial levels. [15,16] Therefore, recent research trends in electrocatalytic reduction of CO 2 have been shifting toward the development of molecular catalysts that can exist as either solutes in electrolytes or can be surface-confined on electrodes. [13,16] The tunable nature and electronic characteristics of molecular catalysts give access to a large variety of catalysts with high activity, selectivity, and durability, as well as their ability to be integrated into sophisticated nanoassemblies. [17][18][19] Thanks to the aforementioned proprieties, performing CO 2 reduction using molecularly defined compounds offer several advantages compared to classical solid-state counterparts. Molecular catalysts usually exhibit well-defined homogeneous and/or CO 2 reduction using molecular catalysts is a key area of study for achieving electrical-to-chemical energy storage and feedstock chemical synthesis. Compared to classical metallic solid-state catalysts, these molecular catalysts often result in high performance and selectivity, even under unfavorable aqueous environments. This review considers the recent state-of-the-art molecular catalysts for CO 2 electro...

Two‐dimensional (2D) materials have attained widespread research interest in renewable energy generation and storage applications. The 2D materials hold the potential to overcome limitations in the classic renewable energy harvesting technology and are expected to revolutionize the standard materials with magnificent performance and low production cost in the future era of renewable energy. In this article, we review certain novel 2D materials for renewable energy devices with a special focus on electrochemical‐based hydrogen generation approaches as green, clean, and zero‐carbon fuels. Besides, the article covers the atmospheric CO 2 reduction approach for the synthesis of hydrocarbon fuels and conversion of H 2 into ammonia through N 2 reduction using 2D material–based photo/electrocatalytic pathways.
