Single‐atom catalysis has become a new branch in heterogeneous catalysis. Although the naturally produced SiO 2 ‐based materials are abundant and stable, fabrication of single‐atom catalysts on such supports with high loading remains as a formidable challenge due to the lack of bonding sites to anchor the isolated metal species. Herein, modifying the diatomite, a kind of pure SiO 2 mineral, with CeO 2 nanoparticles is demonstrated to increase the defect sites on the support. The enhanced metal‐support interaction maintains the atomic dispersion of Pt species with above 1 wt.% loading, exhibiting good performance in the selective hydrogenation of phenylacetylene to styrene.
