Water splitting has been regarded as a sustainable and environmentally-friendly technique to realize green hydrogen generation, while more energy is consumed due the high overpotentials required for anode oxygen evolution reaction. Urea electrooxidation, an ideal substitute, thus received increasing attention in assisting water-splitting reactions. Note that highly efficient catalysts are still drive urea oxidation, facile generation of valence state species significant reaction based on electrochemical-chemical mechanisms. The cost rareness make noble metal impossible further consideration large-scale application. Ni-based very promising their cheap price, structure tuning, good compatibility, easy active phase formation. In light advances made recently, herein, we reviewed recent powder oxidation fundamental firstly presented clarify mechanism urea-assisted water splitting, then prevailing evaluation indicators briefly expressed electrochemical measurements. catalyst design principle including synergistic effect, electronic defect construction surface reconstruction well main fabrication approaches various assisted summarized discussed. problems challenges also concluded fabrication, performance evaluation, Considering key influencing factors catalytic process application, should be given structure−property relationship deciphering, novel development real device; specifically, effort directed with multi-functions simultaneously promote steps anti-corrosion ability by revealing local integration practical We believe current summarization will instructive helpful understanding action via technique.

Nitrogen atom-rich heterocycles and organic azides have found extensive use in many sectors of modern chemistry from drug discovery to energetic materials. The prediction understanding their properties are thus key the safe effective application these compounds. In this work, we disclose multivariate linear regression modeling for decomposition temperature impact sensitivity structurally diverse tetrazoles azides. We report a data-driven approach property featuring collection quantum mechanical parameters computational workflows. statistical models reported herein carry predictive accuracy as well chemical interpretability. Model validation was successfully accomplished via tetrazole test sets with generated exclusively silico. Mechanistic analysis indicated distinct divergent pathways thermal impact-initiated decomposition.
