Firstly, we consider a commercial polysilazane (PSZ) and Ni and Fe chlorides to be mixed in N,N\u2010dimethylformamide (DMF) and deliver\u00a0after overnight solvent reflux a series of Ni\u2212Fe\u2009:\u2009organosilicon coordination polymers. The latter are then heat\u2010treated at 500\u2009\u00b0C in flowing argon to form the title compounds.

Hence, encapsulated NPs are rendered accessible to promote electrocatalytic water oxidation.

This high catalytic performance (considering that the metal mass loading is as low as 0.24\u2005mg\u2009cm<jats:sup>\u22122<\/jats:sup>) is rather stable as observed after an activation step; thus, validating our synthesis approach. This is clearly attributed to both the strong NP\u2010matrix interaction and the confinement effect of the matrix as highlighted through <jats:italic>post mortem<\/jats:italic> microscopy observations.<\/jats:p>","DOI":"10.1002\/cssc.202400561","type":"journal-article","created":{"date-parts":[[2024,6,22]],"date-time":"2024-06-22T03:29:37Z","timestamp":1719026977000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Encapsulating Nickel\u2010Iron Alloy Nanoparticles in a Polysilazane\u2010Derived Microporous Si\u2212C\u2212O\u2212N\u2010Based Support to Stimulate Superior OER Activity"],"prefix":"10.1002","volume":"17","author":[{"given":"Marwan Ben","family":"Miled","sequence":"first","affiliation":[{"name":"CNRS IRCER UMR 7315 Univ.
