Using　a　citrate-assisted　liquid　phase　co-precipitation　method,　a　CuCoAl-LDH　composite　nanomaterial　was　successfully　synthesized　in　situ　on　rGO　and　applied　to　alcohol　synthesis　for　the　first　time.　Structural　characterization　and　morphological　observations　indicate　that　the　hybrid　material　consists　of　hexagonal　LDH　nanosheets　that　are　vertically　aligned,　crossed　and　densely　distributed　on　the　rGO　surface.　The　graphene　support　significantly　promoted　the　dispersion　of　LDH　and　prevented　strong　interlayer　stacking　during　LDH　crystal　growth.　After　optimization　of　the　Co/Cu　ratio,　the　Cu2Co1/Al2O3/rGO　catalyst　exhibited　a　total　alcohol　selectivity　of　60　%,　of　which　82　%　were　C2+　alcohols,　and　no　deactivation　was　observed　after　100　h　of　reaction.　The　addition　of　the　graphene　support　significantly　reduced　the　particle　size　of　the　Cu-Co　alloy　on　the　catalyst　surface,　and　the　particles　were　highly　dispersed　on　both　the　Al2O3　matrix　and　the　rGO　surface.　This　dispersion　facilitated　strong　interactions　between　the　Cu-Co　alloy　particles,　while　the　high　thermal　conductivity　of　graphene　effectively　suppressed　the　formation　of　hotspots.　In　addition,　the　well-ordered　three-dimensional　nanosheet　structure　of　the　LDH　precursor　provides　a　large　specific　surface　area　and　highly　uniformly　dispersed　active　centers.　This　structure　not　only　promotes　the　formation　of　bridge　adsorption　sites　with　high　CO　dissociation　ability,　which　balances　multiple　bonding　and　bridge　CO　adsorption,　but　also　significantly　increases　the　probability　of　CO　insertion,　thereby　enhancing　the　performance　of　HAS.　This　study　provides　an　effective　method　for　the　preparation　of　LDH/　rGO　composites,　demonstrating　their　broad　potential　application　prospects.
