Summary: The electrolysis of CO2 in molten carbonate presents a promising alternative approach for synthesizing carbon nanomaterials with low cost and high yield. This study focuses on the controlled electrochemical conditions to split atmospheric CO2 into carbon nanotubes and macroscopic assemblies of CNTs. The research also explores the structures of CNT morphologies and the growth mechanisms in molten carbonate. These findings provide new insights and methods for the production of carbon nanomaterials.

Summary: This study introduces a new method of synthesizing carbon fullerene allotropes using molten carbonate electrolysis and greenhouse CO2 as the reactant. It demonstrates the transformation of CO2 into various nanostructures with unique properties, such as high strength, electrical and thermal conductivity, flexibility, charge storage, lubrication, and robustness. The electrolysis method described in this study is more cost-effective and has a lower carbon footprint compared to the conventional chemical vapor deposition method.

Summary: This study investigated the influence of copper content and particle morphology on the performance of Cu/FeOx catalysts in the gas-phase conversion of CO2 with hydrogen. The findings indicate potential new ways of tuning the morphology and composition of iron-oxide-based particles, ultimately yielding catalyst compositions and morphologies with variable catalytic performances.

Summary: This study investigates the effects of temperature and potassium promoter on the conversion of syngas to liquid fuels using waste biomass-derived activated carbon and carbon-supported iron-based catalysts. The results show that the addition of potassium promoter significantly increases the gasoline and diesel production, and the iron particles are evenly distributed on the surface of activated carbon.

Summary: In this study, a series of Ni-xSi/ZrO2 catalysts with different Si contents were prepared and investigated for CO2 methanation. The results showed that adding an appropriate amount of Si could enhance the catalytic performance, with the Ni-0.1Si/ZrO2 catalyst exhibiting the highest activity and stability among all tested catalysts.

Summary: The catalytic conversion of CO2 into valuable chemicals and fuels using green hydrogen is seen as a promising approach to reducing CO2 emissions. However, the identification of efficient catalysts for producing light olefins from CO2 faces challenges such as low selectivity and catalyst deactivation. This review covers the dominant reaction pathways, mechanistic insights, deactivation mechanisms, and recent progress in catalyst development for enhanced olefin yields and stability through various catalyst functionalities.
