“…Interestingly, the catalysts employed in EDR (Table ) are very similar to those used in MDR. As recently reported by Wang et al, MOFs could be used to develop nanocatalysts for ethanol dry reforming . The authors used Co and Ce metal nodes and H 2 BDC (terephthalic acid), to create a CoCe-BDC MOF, and compared its catalytic performance with the standard Co 3 O 4 /CeO 2 catalyst.…”

Carbon capture is an emerging technology that is often mentioned as a potential solution to the global warming crisis. However, most of the captured carbon is now treated as waste, discarded, and not used in any meaningful way. On the other hand, from a sustainable development point of view, CO 2 valorization could be a very appealing approach that offers an economic potential when this compound is recycled into valuable chemical products. In this regard, this state-of-the-art review encompasses a wide range of different processes to achieve the conversion of CO 2 into a large variety of products. It does not focus solely on a specific reaction or method, but rather brings different aspects together to provide a far more complete portrait of this emerging subject. Several methods and approaches are discussed, namely thermochemical, electrochemical, photochemical, photoelectrochemical, biochemical, and plasma-assisted conversion. The current state of CO 2 valorization, as well as emerging alternatives and stimulating prospects, was examined, while bearing in mind the realities that limit the application of such technologies. Special emphasis was placed on the optimization of reaction conditions and the development of materials that ensure the best possible production of valuable and environmentally friendly compounds from CO 2 . This review also highlights the challenges related to the application of CO 2 valorization at an industrial scale, which are also important in directing further research in this domain and assessing the prospects of these technologies. Due to the growing number of published papers on the subject, and the limited number of papers offering such a large perspective, we thus believe that this review will be a valuable addition to guide all researchers involved in the field of CO 2 valorization, but also for industrial and political leaders interested in investing in and developing these promising new technologies.

Metal–organic frameworks (MOFs) have emerged as promising materials for triboelectric nanogenerators (TENGs), but the effects of ligand choice on triboelectric charge remain underexplored. Hence, this paper demonstrates the effect of single, binary, and ternary ligands on TENG performance of cobalt/cerium‐based (Co─Ce) bimetallic MOFs utilizing 2‐methylimidazole (2Melm), terephthalic acid (BDC), and benzene tricarboxylic acid (BTC) as ligands. The detailed structural characterization revealed that varying ligand chemistries led to distinct MOF features affecting TENG performance. Single ligand bimetallic MOFs (designated as CoCe‐2MeIm, CoCe‐BDC, CoCe‐BTC) has lower performance than binary ligand (designated as CoCe‐2MeIm‐BDC, CoCe‐2MeIm‐BTC, CoCe‐BDC‐BTC) and ternary ligand MOFs (designated as CoCe‐2MeIm‐BDC‐BTC). Among all, the binary ligand MOF, CoCe‐2MeIm‐BTC, shows the best results (598 V, 26.7 µA) due to the combined effect of imidazole ring and (─COO─) groups. This is attributed to lone pairs on nitrogen atoms and a delocalized π‐electron system in imidazole system in this material. CoCe‐BTC has the lowest results (31 V, 3.2 µA) due to the bulkier nature of the electron‐withdrawing (─COO─) groups and their impact on the π‐electron system of the benzene ring. This study showcases the potential of ligand chemistry manipulation to control triboelectric charge and thereby enhance MOF‐based TENG performance.

Biomass plays a significant role in replacing fossil resources, and catalytic transformation of platform chemicals to high‐value chemicals is an effective approach to maximize the utilization of biomass. Among of which, efficient and durable catalysts are the heart for upgrading of these platform chemicals, and metal–organic frameworks (MOFs)‐derived catalysts have attracted much attentions due to their suitable and versatile physicochemical properties. In this work, we present a short review on the applications of MOFs‐derived catalysts in upgrading of platform chemicals. The design and synthetic strategies of MOFs‐derived catalysts were summarized in detail, and their application in the catalytic upgrading of glycerol, ethanol, furanic compounds, levulinic acid and vanillin were addressed. The final section outlines the potential industrial applications of MOFs‐derived catalysts for upgrading platform chemicals.
