However, they are usually generated at low metal loadings and susceptible to severe reaction conditions resulting in metal sintering, which can be overcome by a new synthesis method offering strong metal？support interaction. Here we show a great potential of one-pot solvent deficient precipitation (SDP) affording mesoporous Pt？Al2O3 (MPtA). This method is unique in creating Pt single atoms and clusters at up to 3 wt% loading because of the restricted Pt mobility by contiguous Al2O3 particles. The MPtA of 3 wt% Pt, representing ensemble species of single atoms and clusters, is more active and stable than the general impregnated catalyst comprised of Pt nanoparticles. Moreover, it successfully accomplishes reversible H2 release and charge of commercial benzyltoluene-type hydrogen carriers. The size and activity of Pt species is readily tuned in the MPtA, which will exert remarkable impacts on catalysis. ？ 2022 Elsevier B.V.
