The　cryptomelane-type　manganese　oxide　octahedral　molecular　sieve　(OMS-2)-supported　Pd　(0.5　wt%　Pd/OMS-2-DP,　0.5　wt%　Pd/OMS-2-PI,　and　0.5　wt%　Pd/OMS-2-EX)　catalysts　were　prepared　by　the　deposition-precipitation,　pre-incorporation,　and　ion-exchanging　strategies,　respectively.　It　is　shown　that　the　preparation　method　exerted　an　important　effect　on　the　physicochemical　property　of　the　sample.　Among　the　OMS-2-supported　Pd　catalysts,　0.5　wt%　Pd/OMS-2-DP　possessed　the　highest　surface　(Mn2+　+　Mn3+)/Mn4+　atomic　ratio　and　the　highest　surface　Pd　loading　and　acid　sites.　The　0.5　wt%　Pd/OMS-2　catalysts　outperformed　the　Pd-free　counterpart,　among　which　0.5　wt%　Pd/OMS-2-DP　presented　the　best　catalytic　activity　(T-50%　and　T-90%　were　25　and　55　degrees　C　for　CO　oxidation,　240　and　285　degrees　C　for　toluene　oxidation,　and　160　and　200　degrees　C　for　ethyl　acetate　oxidation,　respectively).　We　believe　that　the　high　Pd　surface　loading,　high　surface　atomic　ratio　of　(Mn2+　+　Mn3+)/Mn4+,　and　good　low-temperature　reducibility,　good　oxygen　mobility,　and　high　acidity　were　responsible　for　the　excellent　performance　of　the　0.5　wt%　Pd/OMS-2-DP　catalyst.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
