Article Abstract
The urea oxidation reaction (UOR) with low required oxidation potential is not only an energy-saving strategy for efficient hydrogen production but also offers an effective way to treat wastewater by decomposing urea. An amorphous cobalt oxyborate with optimum vanadium doping has been identified as an efficient electrocatalyst for UOR for the first time with great stability. The electrocatalyst requires only 1.37 V potential to achieve a current density of 20 mA cm. Impressively, the developed electrocatalyst exhibited very active and long stability in alkaline raw bovine urine as extreme urine sewage media coupled with efficient hydrogen production at the cathode.

Resolving the three-dimensional structure of transition metal oxide nanoparticles (TMO-NPs), upon self-restructuring from solution, is crucial for tuning their structure-functionality. Yet, this remains challenging as this process entails complex structure fluctuations, which are difficult to track experimentally and, hence, hinder the knowledge-driven optimization of TMO-NPs. Herein, we combine high-energy synchrotron X-ray absorption and X-ray total scattering experiments with atomistic multiscale simulations to investigate the self-restructuring of self-assembled Co-NPs from solution under dark or photocatalytic water oxidation conditions at distinct reaction times and atomic length-scales.
