Summary: Heterogeneous molecular catalysts based on transition metal complexes are increasingly being studied for their potential use in electrochemical energy conversion. This review discusses how tuning the first and second coordination spheres of these complexes can optimize their activities and serve as models for studying the impact of structural variations on activity. Structural tuning, such as adjusting ligated atoms and appending adjacent metal centers or pendant groups, can result in different geometric and electronic configurations of the complexes, ultimately leading to improved activity through stability adjustments and redox behaviors.

Summary: This study reports the use of hierarchical porous hollow N-doped Cu-based nanocages (HPH-N-Cu NCs) as a highly sensitive electrochemical sensing platform for organophosphates pesticide detection. The HPH-N-Cu NCs exhibit unique micro-/mesoporous structures, changeable valence state of copper, and heteroatom doping, resulting in more exposed active sites, multiple reaction interfaces, and enhanced conductivity. The AChE biosensor based on HPH-N-Cu NCs shows high electrocatalytic ability towards the oxidation of electroactive products, achieving a low detection limit and a wide detection range for methamidophos.

Summary: A highly (111)-oriented Cu foil electrocatalyst with dense twin boundaries (tw-Cu) is demonstrated to exhibit high selectivity towards CH4 in the electrochemical carbon dioxide reduction reaction. The tw-Cu catalyst achieves a high Faradaic efficiency of 86.1 +/- 5.3% for CH4 production. Theoretical studies suggest that tw-Cu reduces the reduction barrier for the rate-determining hydrogenation of CO compared to planar Cu(111), leading to the observed high CH4 selectivity.
