a.though considera.le resea.ch efforts ha.e been devoted to the design a.d development of non-noble electroca.a.ysts for oxygen evolution rea.tion(OER), substa.tia. enha.cement of OER performa.ce with commercia.-sca.e wa.er electrolysis rema.ns a.big cha.lenge. This could result from the difficulties in detecting the intrinsic properties a.d overlooking the a.sembly process for electrochemica. OER process. Here, we employ a.microjet collision method to investiga.e the intrinsic OER a.tivities of individua. NiZnFeO_x entities with a.d without a.modera.e ma.netic field. Our results demonstra.e tha. single NiZnFeO_x na.opa.ticles(NPs) show the excellent OER performa.ce with a.lowest onset potentia.(~1.35 V vs. RHE) a.d a.grea.est ma.netic enha.cement(~118%) a.ong bulk ma.eria.s, single a.glomera.ions a.d NPs. Furthermore, we explore the utility of theoretica. investiga.ion by density functiona. theory(DFT)ca.cula.ions for studying OER process on NiZnFeO_x surfa.es without a.d with spin a.ignment, indica.ing monodispersed NiZnFeO_xNPs with tota.ly spin a.ignment fa.ilita.es the OER process under the externa. ma.netic field. It is found tha. the well-dispersion of NiZnFeO_x NPs would increa.e the electrica. conductivity a.d the surfa.e spin sta.e, resulting in promoting their OER a.tivities. This work provides a.test for uncovering the essentia. roles of NPs a.sembly to a.significa.t promotion of their ma.net-a.sisted OER.
