Special Issue Information

Dear Colleagues,

Due to the emergence of an energy crisis and the proliferation of environmental pollution, the development of advanced energy conversion technologies has attracted considerable and persistent attention in recent years. The core component of these energy conversion systems is the electrocatalytic material, which largely determines their practical performance and service life. Therefore, many efforts have been devoted to the exploration of rationally designed electrocatalysts with well-defined nanostructures and enhanced electrochemical activity. Considering the rapid progress made in this emerging field, this Special Issue aims to collect recent scientific advancements related to novel electrocatalytic materials; this particularly includes the engineering of catalyst nanostructures for various energy conversion applications, such as the  hydrogen evolution reaction (HER), oxygen evolution reaction (OER), oxygen reduction reaction (ORR), alcohol oxidation reaction (AOR), carbon dioxide reduction reaction, nitrogen reduction reaction, and so on. We welcome the submission of original research articles, reviews and short communications.

If you would like to submit papers to this Special Issue or have any questions, please contact the in-house editor, Ms. Rita Lin (rita.lin@mdpi.com).

Electrocatalytic synthesizing of urea through C-N coupling of CO2 and NO3 under ambient conditions is a possible solution for the problem of energy consumption in commercial urea production. Herein, we report a Cu-doped CeO2 catalyst anchored on delaminated MXene two-dimensional surface. The Cu-CeO2/MXene catalyst achieves the co-reduction of CO2 and NO3 to synthesize urea, obtaining a urea yield rate of 505.1 μg·h−1·mgcat.−1 with a Faradic efficiency (FE) of 6.3% at −0.8 V versus reversible hydrogen electrode (vs. RHE). Theoretical calculations further demonstrate that Cu doping is capable of enhancing the activity of Cu-Ce sites and promoting C-N coupling and protonation reactions. Full article
