Metal-organic framework (MOF) backbone materials, as nanoporous have outstanding performance in studies on adsorption and catalysis by virtue of their high porosity, large specific surface area, unsaturated metal coordination sites, diverse structures functions. However, it is difficult to synthesize truly perfect MOFs practical experiments because any slight change reaction conditions may lead defects the material. This suggests that be prevalent a systematic understanding would beneficial controlling material properties. Meanwhile, detection synthesis defective MOF materials are still development stage. In this paper, methods, characterization techniques, optimization strategies reviewed. paper discusses current difficulties makes suggestions for future work.

Achieving high activity and selectivity of multicarbon products in the CO2 reduction reaction (CO2RR) on Cu-based electrocatalysts remains challenging due to limited concentration local OH–, sluggish diffusion, competitive hydrogen evolution reaction. Herein, we report aerophilic nanocomposites hydrophobic SiO2 aerosol Cu2O nanocubes tailor microenvironment for enhancing electroreduction 0.1 M KHCO3 aqueous electrolyte. Combined situ infrared analysis, molecular dynamics simulations, density functional theory calculations reveal that composite Cu2O/SiO2 enriches hydroxyl by blocking between OH– HCO3–, accelerates diffusion coefficient (from 2.67 × 10–10 8.46 m2 s–1), renders a lower dissociation energy H2O than bicarbonate (0.49 vs 1.24 eV (111)) as compared neat Cu2O. Consequently, promotes formation C2+ (Faradaic efficiency FEC2+ from 52.4 75.6%) suppresses generation (FEH2 30.0 9.6%) at −1.2 V versus reversible electrode. The results provide insight into improvement CO2RR electrocatalysis regulating alkalinity, transportation, permeability.

Abstract Electrochemical CO 2 reduction reaction (CO RR) powered by renewable energy provides a promising route to conversion and utilization. However, the widely used neutral/alkaline electrolyte consumes large amount of produce (bi)carbonate byproducts, leading significant challenges at device level, thereby impeding further deployment this reaction. Conducting RR in acidic electrolytes offers solution address “carbonate issue”; however, it presents inherent difficulties due competitive hydrogen evolution reaction, necessitating concerted efforts toward advanced catalyst electrode designs achieve high selectivity activity. This review encompasses recent developments RR, from mechanism elucidation design engineering. begins discussing mechanistic understanding pathway, laying foundation for RR.
