Efficient　utilization　of　hydrocarbon　fuels　holds　great　significance　for　the　current　vehicle　low-emission　requirements　and　future　carbon-neutral　society.　However,　the　scenario　that　limits　the　effective　fuel　use　and　combustion　is　the　present　undesirable　hydrocarbon-cracking　catalysts　of　low　activity,　serious　coking,　and　easy　degradation.　To　tackle　these　issues,　we　rationally　designed　and　synthesized　an　active,　anti-coking,　and　recyclable　all-in-one　zeolite@Ru–Al2O3　catalyst　on　FeCrAl　support　by　steam-assisted　crystallization　and　atomic　layer　deposition.　Ru　nanoclusters　dispersedly　on　ZSM-5　can　boost　the　catalytic　efficiency　for　hydrocarbon　cracking　and　anti-coking,　while　the　protective　Al2O3　thin　layers　further　ensure　the　reusable　economy.　As　for　n-dodecane　(C12H26)　cracking　reaction,　the　ZSM-5@Ru–Al2O3　showed　a　high　unit　activity　up　to　0.1253%·ml·mg−1·min−1,　low-carbon　deposition　rate,　and　the　enhanced　first-cycle　carbon　removal　rate　of　78.3%　for　recyclable　use.　Density　functional　theory　(DFT)　calculations　have　further　confirmed　that　high　catalytic　efficiency　and　low-carbon　deposition　benefit　from　the　timely　adsorption　of　C12H26　and　timely　transfer　of　reactant　products　at　the　composite　interface.　This　work　opens　interesting　possibilities　for　the　rational　design　and　fabrication　of　high-efficient,　anti-coking,　and　recyclable　hydrocarbon　cracking　catalysts　through　multifunctional　structural　regulations.　©　2022　Elsevier　Ltd
