Nickel-doped iron oxide/graphene oxide powders were synthesized by the co-precipitation method varying Ni/Fe ratio, and activity of materials towards oxygen reduction reaction in a microbial fuel cell (MFC) was studied. The samples presented X-ray diffraction peaks associated with magnetite, maghemite Ni ferrite, as well evidence hematite. Raman spectra confirmed presence (γ-Fe2O3) NiFe2O4. Scanning electron micrographs showed exfoliated sheets decorated nanoparticles, transmission spherical nanoparticles about 10 nm diameter distributed on individual graphene sheet. electrocatalytic for (ORR) studied cyclic voltammetry an air-saturated electrolyte, finding that best catalyst sample 1:2 using concentration 15 mg·cm−2 graphite felt. provided potential 397 mV maximum current −0.13 mA; comparison, electrode prepared GO/γ-Fe2O3 ORR 369 −0.03 mA. Microbial cells vertical proton membrane Ni-doped Fe3O4 Fe3O4/graphene tested 24 h; they reached stable OCV +400 +300 OCV, efficiency 508 mW·m−2 139 mW·m−2, respectively. better performance material attributed to combined catalytic between γ-Fe2O3 NiFe2O4, coupled lower wettability, which led dispersion onto electrode.

Seawater electrocatalysis holds significant promise as a technology for hydrogen production. A simple and low-cost impregnation-hydrothermal thermal reduction strategy was used to synthesize in situ constructed three-dimensional porous trimetallic (Pd, Fe, Co) anchored on cheap high-conducting carbon paper (CP) electrode water electrolysis alkaline media. The fabricated PdFeCo 1−x ONPs@CP had super-hydrophilic superaerophobic properties, allowing the efficient removal of oxygen bubbles from surface due close interaction between electrolyte. Furthermore, synergistic effect trimetallics CP-fibers significantly increased OER intrinsic activity. catalyst demonstrated critical low overpotentials 220 300 mV, resulting an extraordinarily high current density 100 mA cm −2 . For full cell overall splitting performance, 140 151 mV were needed drive 10 seawater solution electrolytes.
