Platinum-based　materials　are　identified　as　the　most　effective　electrocatalysts　for　the　hydrogen　evolution　reaction　(HER)　in　acidic　media.　However,　the　scarcity　and　high　cost　of　platinum　(Pt)　have　limited　its　wide　application.　Therefore,　catalysts　with　low　loading　but　high　intrinsic　activity　can　promote　the　wide　application　of　Pt.　In　this　work,　we　creatively　applied　plasma　sputtering　to　deposit　Pt　single　atoms　on　TiO2-X　as　an　efficient　hydrogen　evolution　reaction　(HER)　catalyst.　The　catalyst　shows　high　intrinsic　activity　and　superior　stability　in　acid　media,　with　high　turnover　frequency　(38.9H(2)　s(-1))　and　mass-specific　activity　(39.1　A/mg　Pt)　at　50　mV　(vs.　RHE)　overpotential　in　0.5　M　H2SO4　that　are　respectively　3.3　and　11.04　times　greater　than　those　of　the　commercial　20%　Pt/C　catalyst.　In　particular,　the　plasma　sputtering　method　used　in　this　work　can　shorten　the　synthesis　period　of　the　catalyst　to　＇minutes＇　or　even　＇seconds.＇　This　work　provides　guidance　and　inspiration　for　the　fast　synthesis　of　catalysts　with　high　intrinsic　activity　for　various　applications.　(C)　2021　Elsevier　Ltd.　All　rights　reserved.
