In recent years, metal-organic frameworks(MOFs) have been extensively investigated as electrocatalysts due to their highly efficient electroreduction of CO_(2). Herein,the electrocatalytic CO_(2)reduction reaction was investigated by growing helical Cu-porphyrinic MOF Cu meso-tetra(4-carboxyphenyl)porphyrin(TCPP) on Cu(OH)_(2) nanoarrays(HCu TCPP@Cu(OH)_(2)) using a sacrificial template method. The electrocatalytic results showed that the H-Cu TCPP@Cu(OH)_(2) nanoarrays exhibited a high acetic acid Faradaic efficiency(FE) of 26.1% at-1.6 V vs. Ag/Ag^(+), which is much higher than the value of 19.8% obtained for non-helical Cu TCPP@Cu(OH)_(2)(n H-Cu TCPP@Cu(OH)_(2)). The higher efficiency may be because space was more effectively utilized in the helical MOF nanoarrays, resulting in a greater number of active catalytic sites. Furthermore, in situ diffuse reflectance infrared Fourier transform spectra showed that the H-Cu TCPP@Cu(OH)_(2) nanoarrays have much stronger CO linear adsorption, indicating a better selectivity of acetic acid than that of n H-Cu TCPP@Cu(OH)_(2). In this study, we develop new helical nanomaterials and propose a new route to enhance the reduction of CO_(2).
