Global warming and the global energy crisis are two major challenges humanity is currently confronting that pressuring scientific community to find efficient, low-cost, environmentally sustainable solutions. Within this context, hydrogen has emerged as a clean efficient carrier promising replace hazardous fossil fuels. The present study, of relevance water splitting domain, concerns synthesis novel hybrid structures, namely polyvinylpyrrolidone (PVP) functionalized with Ag-doped LaMnO3 Pd-doped LaMnO3, respectively. electrolysis catalytic activity these new materials was evaluated in strongly alkaline medium. Perovskite-based modified electrodes were manufactured through four different procedures. samples displayed electrocatalytic for O2 evolution reaction most active electrode one obtained by drop-casting mixture LaMnO3:Ag/PVP Carbon Black on graphite support. study aimed at succeeds increasing database concerning role perovskite oxides water-splitting field.

The oxygen evolution reaction (OER) is the main bottleneck in water splitting and other key technologies due to its slow kinetics. development of low-cost, highly active, stable, more efficient electrocatalysts as an alternative commonly expensive scarce Ir- Ru-based catalysts used necessary. present work reports preparation OER by a straightforward easy method based on synergistic effect Ni/Ferrocene combination that leads high current densities, lower overpotential, stability, low Tafel slope alkaline conditions. optimized catalyst demonstrates exceptional performance, providing constant potential ∼1.51 ∼1.65 V overpotentials ∼0.278 ∼0.420 for than 26 46 h at densities 10 100 mA·cm-2, respectively. It represents important significant advance obtaining electrocatalyst materials anodes without need previous tedious synthetic procedures. Only commercial chemicals with amounts metals are employed, thus facilitating this Ni/ferrocene configuration could be scaled up real devices.
