NaBH-reduction induced tunable oxygen vacancies in LaNiO to enhance the oxygen evolution reaction

Tunable oxygen vacancies of LaNiO 3 (LNO- V o) are realized by theoretical prediction and the NaBH 4 -reduction approach. The LNO 2.7 catalyst exhibits superior catalytic activity and long-term stability for water oxidation. Direct evidence of the active site center and the intermediates is observed...

Summary:Tunable oxygen vacancies of LaNiO 3 (LNO- V o) are realized by theoretical prediction and the NaBH 4 -reduction approach. The LNO 2.7 catalyst exhibits superior catalytic activity and long-term stability for water oxidation. Direct evidence of the active site center and the intermediates is observed from in situ Raman spectra and DFT calculations. The LNO 2.7 catalyst with superior catalytic activity for water oxidation is realized by NaBH 4 -reduction approach. Direct evidence of the active site center and the intermediates is observed from in situ Raman spectrum and DFT calculation.
