Despite having the potential to synthesize stable metal–organic frameworks (MOFs), rare earth metal-based MOFs have not been exploited extensively. Owing high coordination numbers, can generate a suitable environment for various applications. Herein, samarium (Sm)-based were synthesized with three different organic linkers, namely, trimesic acid (TMA), meso-tetra(4-carboxyphenyl)porphine (TCPP), and 1,3,6,8-tetra(4-carboxylphenyl) pyrene(TBPy) by solvothermal approach. The morphologies of...

Abstract Synthesis of ammonia by electrochemical nitrogen reduction reaction (NRR) is a promising alternative to the Haber–Bosch process. However, it commonly obstructed high activation energy. Here, we report design and synthesis an Al−Al bonded dual atomic catalyst stabilized within amorphous nitrogen‐doped porous carbon matrix (Al 2 NC) with NRR performance. The Al ‐sites act synergistically catalyze complex multiple steps through adsorption activation, enhancing proton‐coupled electron...
