Heterogeneous materials containing molecular catalytic sites show promise for electrocatalytic reduction of CO2 to energy-enriched carbon products. Interactions between the catalyst and heterogeneous support increasingly are recognized as important in governing product selectivity rate. Recent work on Mn(R-bpy)(CO)3Br type catalysts immobilized multiwalled nanotubes (MWCNT) demonstrated control behavior with steric modification catalyst. Phenyl groups installed 4,4' positions bipyridine ligand (ph-bpy) maximized performance through π-π interactions MWCNT support. Herein we report outcome extending π system Mn(nap-bpy)(CO)3Br (nap-bpy = 4,4'-di(naphthalen-1-yl)-2,2'-bipyridine) Mn(pyr-bpy)(CO)3Br (pyr-bpy 4,4'-di(pyren-1-yl)-2,2'-bipyridine) MWCNT. We demonstrate exceptional electrocatalysis Mn(nap-bpy)(CO)3Br/MWCNT (FECO > 92%; JCO 16.5 mA/cm2) find that this electrochemically reduces bicarbonate absence deliberately added at a remarkable overall >80% products (FEHCOO- 52% FECO 29%). diminishing returns simply adding aromatic character bipyridyl Mn(pyr-bpy)(CO)3Br/MWCNT observe unique cambering believe enables selective catalysis. Mechanistic studies were carried out using novel thin-film infrared spectroelectrochemical (IR-SEC) technique. These experiments undergo single electron Mn-centered radical binds reduction-coupled process.

Abstract Electrocatalysis is a crucial technology that will enable future low‐carbon chemical production and energy beyond fossil fuels. Notwithstanding the intense growing research in area, potentialities of field are largely unexplored. We provide case examples discuss emerging possibilities have still not been investigated enough but necessary to exploit this potential e‐chemistry. Starting from defining trends setting scene, as well clarifying difference between electrochemistry electrocatalysis, some elements vision foster innovation discussed. The aim stimulate discussion reflection rather than review state‐of‐the‐art. Aspects discussed regard i) passing electro photoelectrocatalytic approaches, ii) making chemicals air, iii) exploitation both anodic cathodic reactions, tandem/paired electrocatalytic iv) for selective oxidation mediated synthesis. Priorities strategies an e‐chemistry Intensifying these directions extending still‐too‐limited current including modelling design, effort accelerate realisation distributed

Molecular catalysts with functional group decorations are promising for electrocatalytic CO 2 reduction to produce valuable chemicals and fuels. Using nickel phthalocyanine derivatives cyano, methoxy, dimethylamino groups, this study unveils why decorating molecular either electron-donating or electron-withdrawing groups can enhance their activity. Notably, the group–decorated catalyst demonstrated stable nearly 100% -to-CO selectivity over a wide potential range high partial current densities up 300 milliamperes per square centimeter. Theoretical in situ spectroscopic analyses revealed critical role of dynamic protonation ligand sites activating metal center, which be facilitated by decoration groups. Conversely, although requiring higher energy protonation, synergy between centers protonated sites, favoring formation key *COOH intermediates improving at bias. This underscores importance optimizing functionalized enhanced RR
