Abstract Electrochemically reducing CO 2 to more reduced chemical species is a promising way that not only enables the conversion of intermittent energy resources stable fuels, but also helps build closed-loop anthropogenic carbon cycle. Among various electrocatalysts for electrochemical reduction, multifunctional metal–organic frameworks (MOFs) have been employed as highly efficient and selective heterogeneous due their ultrahigh porosity topologically diverse structures. Up now, great progress has achieved in design synthesis active MOF-related catalysts reduction reaction (CO RR), corresponding mechanisms thoroughly studied. In this review, we summarize recent applying MOFs derivatives RR, with focus on strategies electrolyzers.

Electrocatalytic CO2 reduction reactions (CO2RR) based on scalable and highly efficient catalysis provide an attractive strategy for reducing emissions. In this work, we combined first-principles density functional theory (DFT) machine learning (ML) to comprehensively explore the potential of double-atom catalysts (DACs) featuring inverse sandwich structure anchored defective graphene (gra) catalyze CO2RR generate C1 products. We started with five homonuclear M2⊥gra (M = Co, Ni, Rh, Ir, Pt), followed by 127 heteronuclear MM′⊥gra Pt, M′ Sc–Au). Stable DACs were screened evaluating their binding energy, formation dissolution metal atoms, as well conducting molecular dynamics simulations without solvent water molecules. Based DFT calculations, Rh2⊥gra DAC was found outperform other four Rh-based single- noninverse structures. Out DACs, 14 be stable have good catalytic performance. An ML approach adopted correlate key factors activity stability including sum radii ligand atoms (dM–M′, dM–C, dM′–C), difference electronegativity two (PM + PM′, PM – PM′), first ionization energy (IM IM′, IM IM′), electron affinity (AM AM′, AM AM′), number d-electrons (Nd). The obtained models further used predict 154 electrocatalysts out 784 possible same configuration. Overall, work not only identified promising reported but also provided insights into atomic characteristics associated high activity.
