Depolymerizing　lignin　to　produce　high-value　chemicals　under　mild　conditions　is　a　significant　way　to　achieve　the　sustainable　development　of　agriculture　and　forestry　industry,　and　attracting　a　growing　number　of　attentions.　In　this　work,　a　bimetallic　Ni-Co　catalyst　(CoNi2@BTC)　was　prepared　by　using　MOF　as　precursor　and　then　employed　to　degrade　the　lignin　model　compounds　and　real　corncob　lignin.　The　resulted　CoNi2@BTC　mainly　composed　of　Co0,　Ni0,　Co　and　Ni　oxides.　Compared　to　the　pure　Co@BTC　and　Ni@BTC,　CoNi2@BTC　exhibited　much　better　(4.0–4.75　times)　performance　on　cracking　the　ether　bonds　without　H2.　During　the　degradation　of　lignin　model　compounds,　CoNi2@BTC　could　not　only　completely　crack　the　various　ether　bonds　(α-O-4,　β-O-4　and　4-O-5),　but　also　further　hydrogenate　the　intermediates,　resulting　the　highly　selective　yield　of　cycloparaffin　(＞79.58　%)　and　cyclohexanol　(100　%).　The　mechanism　on　ether　bond　cleavage　was　ascribed　into　the　weakly　acidic　site　originating　from　Co　and　the　strongly　acidic　site　stemming　from　Ni,　while　the　further　hydrogenation　was　attributed　into　the　strong　activity　of　Ni　on　activating　H.　Due　to　the　synergistic　effect　of　Ni　and　Co,　CoNi2@BTC　also　exhibited　full　depolymerization　of　real　corncob　lignin　and　achieved　the　high　selectivity　of　cycloparaffin　(80.16　%)　in　the　bio-oil.　This　work　will　provide　a　new　strategy　to　the　resource　utilization　of　the　biomass　waste.　©　2025　Elsevier　B.V.
