This paper systematically investigates the link between anodization parameters and glucose oxidation on thin copper films, unraveling crucial insights into their optimization. By careful control of the anodization parameters, distinct species can be favoured, such as Cu<sub>2</sub>O, Cu(OH)<sub>2</sub>, and CuO, with varying catalytic activities. Applying a polarization in 1 M KOH at 0 V (<em>vs.</em> Ag|AgCl) results in the formation of a highly active surface CuO layer, which delivers significant performance improvements compared to the bare copper electrode. Namely, a 55% sensitivity gain in the 0.1–0.5 mM range, and a remarkable 73% gain in the 0.75–2 mM range. Furthermore, the manufactured electrodes display an extremely low limit of detection – only 0.004 mM. Such an exceptional result can be ascribed to the scalable and reproducible manufacturing done directly on cleanroom-compatible platforms.

Therefore, understanding the crucial factors governing the catalytic performance and long-term stability is fundamental yet challenging due to the structural complexity of heterogeneous catalysts. Herein, ZnO-supported Ni catalysts with different ZnO morphologies were used for CO<sub>2</sub> hydrogenation. The results revealed that catalytic activity and stability were strongly related to weak basic sites and Ni–ZnO interactions, respectively. The Ni/r-ZnO (nanorod) catalyst, which possessed a higher amount of weak basic sites responsible for the adsorption and activation of CO<sub>2</sub>, exhibited better catalytic activity. Nonetheless, r-ZnO, predominantly exposing nonpolar facets, was not conducive to Ni–r-ZnO interactions, which led to the agglomeration of supported Ni species during CO<sub>2</sub> hydrogenation and was the primary cause of the deactivation of the Ni/r-ZnO catalyst. Meanwhile, carbon deposition could be another minor factor affecting catalytic stability. Kinetic and <em>in situ</em> DRIFTS spectroscopy results demonstrated that the reaction proceeded through an H<sub>2</sub>-assisted associated mechanism, with the adsorption and activation of CO<sub>2</sub> as the rate-determining step.
