Abstract The electrochemical CO 2 reduction reaction (CO RR) has been extensively studied because it can be leveraged to directly convert into valuable hydrocarbons. Among the various catalysts, copper nanoclusters (Cu NCs) exhibit high selectivity and efficiency for producing RR products owing their unique geometric/electronic structures. However, influence of protective ligands on performance Cu NCs remains unclear. In this study, is shown that different thiolate ligands, despite having nearly identical geometries, substantially affect stability 14 in RR. Notably, protected by 2‐phenylethanethiolate greater achieve a relatively higher (≈40%) formic acid production compared with cyclohexanethiolate‐protected counterpart. These insights are crucial designing both stable highly selective, enhancing efficacy reduction.

Abstract CO 2 emissions and accumulation in the ecosystem have exacerbated climate change increased global temperature. This study focused on activation of hydrothermally synthesized Cu metal–organic framework (MOF‐199) with potassium citrate (C 6 H 5 K 3 O 7 ) to produce MOF‐derived carbon incorporated nano‐dispersed metallic oxidative species facilitate electrochemical reduction. Among all MOF samples, resulting carbon, activated by C , demonstrated highest electrocatalytic current lowest charge transfer resistance, achieving a Faradaic efficiency exceeding 50% for production acetic acid (CH COOH) at an applied potential − 1.1 V (vs RHE). The addition during preparation endowed mesoporous structure, thereby enhancing adsorption activation. A proposed reaction pathway suggested that generation is critical forming Cu─C bonds producing CH COOH. indicates Cu‐containing beneficial properties applications owing its nanoispersed features could be readily synthesized.
