Electrochemical CO reduction reaction (CORR) presents a unique opportunity to convert carbon dioxide (CO) to value-added products while simultaneously storing renewable energy in the form of chemical energy. However, particle applications of this technology are limited due to the poor efficiency and product selectivity of the existing catalyst. In this study, we demonstrate a facile method for the heat-induced transformation of copper nanowires into CuO/Cu nanotubes with defect-enriched surfaces.

Despite having a lower surface area, larger particle size, and lesser N content, the FC material prepared at a calcination temperature of 900 °C (FC) outperforms the other samples. Deeper investigations revealed that the FC efficiently facilitates the charge transfer process and enhances the diffusion rate of 4-NP, leading to increased surface coverage of 4-NP on the surface of FC.

Substituting water oxidation half of water splitting with anodic oxidation of urea can reduce the cost of H production and provide an avenue for treating urea-rich wastewater. However, developing an efficient and stable electrocatalyst is necessary to overcome the indolent kinetics of the urea oxidation reaction (UOR). Accordingly, we have used the Schikorr reaction to deposit FeO particles on the nickel foam (FeO/NF).
