The　efficient　utilization　of　hydrogen　resources　in　H2S　has　aroused　great　attention　in　both　resource　utilization　and　environmental　protection.　Using　H2S　as　a　hydrogen　resource　donor　for　the　reduction　of　nitrobenzene　to　aniline　could　be　an　effective　method　to　replace　H2.　Herein,　we　fabricated　the　porous　flower-like　CoNi-LDO　catalyst　through　facile　morphology　control　engineering,　which　utilizes　DMF　as　an　intercalating　agent　to　influence　the　structure　and　properties.　Endowed　with　abundant　electron-rich　oxygen　vacancies　and　enhanced　basic　sites　capacity,　the　as-designed　CoNi-D　catalyst　exhibits　considerable　aniline　selectivity　(96　%)　and　high　catalytic　stability　over　seven　cycles　at　110　°C.　The　potential　single　H-induced　dissociation　pathway　for　the　reduction　of　nitrobenzene　to　aniline　by　H2S　was　explored　using　in　situ　FT-IR　analysis.　The　present　study　could　provide　a　feasible　strategy　for　designing　catalysts　for　the　high-value　utilization　of　H2S.　©　2025　Elsevier　B.V.
