One-dimensional　(1D)　CeO2　nanotubes　can　be　used　as　a　support　to　inhibit　Pd　nanoparticle　aggregation　during　the　high　temperature　calcination　process　in　air.　This　is　in　opposition　to　the　significant　aggregation　of　Pd　particles　that　is　observed　for　the　preparation　of　supported　Pd　metal　catalysts　using　non-1D　commercial　CeO2　as　support.　The　as-prepared　Pd/CeO　2　nanotube　catalyst　exhibits　much　higher　catalytic　performance　than　Pd/commercial　CeO2　toward　the　aerobic　selective　oxidation　of　benzyl　alcohol　to　benzaldehyde.　This　work　suggests　that　1D　metal　oxide　materials　can　be　used　as　a　promising　class　of　supports　to　inhibit　noble　metal　nanoparticle　aggregation,　thereby　improving　catalytic　performance　toward　target　reactions.　©　2013　Dalian　Institute　of　Chemical　Physics,　the　Chinese　Academy　of　Sciences.
