A　highly　dispersed　FeCu/LDH-based　catalyst　precursor　was　prepared　by　co-precipitation　method,　and　the　catalysts　promoted　with　Pd,　Pt　or　Rh　were　then　prepared　using　an　equal-volume　impregnation　method　to　be　used　in　syngas-to-alcohol　reaction.　These　samples　were　characterized　by　XRD,　Raman,　FT-IR,　In-situ　DRIFT,　XPS,　SEM　and　N2　adsorption　desorption.　The　study　reveals　that　the　2D　nanosheet　structure　of　the　LDH　precursor　has　a　large　surface　area　and　evenly　distributed　active　sites,　leading　to　the　superior　catalyst　performance.　The　promoted　catalyst　generated　even　higher　catalytic　activity　and　alcohol　selectivity,　notably　reducing　undesired　methane　and　CO2　by-products.　Rh　incorporation　obviously　enhanced　the　thermal　stability　of　the　catalyst,　leading　to　the　longterm　retention　of　the　LDH　structure.　Rich　-OH　groups　offer　surface　basicity,　thereby　significantly　enhancing　its　catalytic　performance　to　lower　the　CO2　selectivity　to　1.34　%　and　methane　to　1.67　%　while　achieving　a　remarkable　alcohol　selectivity　of　95.1　%.　In-situ　DRIFT　results　reveal　that　Rh　promotion　helps　balance　the　gaseous　adsorption　and　bridge　adsorption　of　CO　for　improved　overall　syngas-to-alcohols　reaction　results.
