Abstract Zeolitic imidazolate frameworks (ZIFs) are a subclass of metal–organic framework that have attracted considerable attention as potential functional materials due to their high chemical stability and ease synthesis. ZIFs usually composed zinc ions coordinated with imidazole linkers, some other transition metals, such Cu(II) Co(II), also showing ZIF‐forming cations. Despite the importance nickel in catalysis, no Ni‐based ZIF permanent porosity is yet reported. It found presence arrangement carbonyl groups on linker play crucial role completing preferred octahedral coordination nickel, revealing promising platform for rational design wide range catalytic applications. Herein, synthesis first reported heterogeneous catalysts Suzuki–Miyaura cross‐coupling C─C bond forming reactions demonstrated.

Abstract The attainable region interpretation of the thermodynamic principles has indicated that carbon dioxide (CO 2 ) can be either hydrogenated directly to form dimethyl ether (DME) or gasoline. process converts CO DME is more thermodynamically favourable at lower temperature. A certain temperature range (25 300 °C) suggested for conversion via a methanol intermediate pathway without addition work. Optimal synthesis routes derived from P-graph's mutual exclusion solver were compared with reactions reported in literature and showed great correlation. collectively possess Gibbs free energy less than zero, negative enthalpy reaction. With P-graph technique, case studies have demonstrated gasoline using hydrogenation monoxide Fischer–Tropsch feasible no work heat requirement. Both visual advantage data-driven applications. benefit integrating framework machine learning model like decision tree classifier was also second study as it solves topological optimisation problems scaling constraints.

A low temperature CO2 methanation is a thermodynamically favorable route to produce highly selective methane while preventing catalyst deactivation. Ni-Ba/Sm2O3 catalysts synthesized using one-pot hydrothermal method exhibited enhanced reducibility with high adsorption capacity achieve conversion at temperatures. occurred 200°C 5% conversion, progressively increasing reach equilibrium 400°C 100% selectivity methane. BaO promotes surface oxygen vacancy in Sm2O3, which responsible for forming bidentate formate species during methanation. Comparative DRIFTS analysis impregnation indicates the followed different mechanistic pathways depending on amount of generated by BaO/Sm2O3 proximity.
