Designing　efficient　electrocatalysts　for　efficient　hydrogen　evolution　is　extremely　desired　but　challenging.　Herein,　we　report　a　facile　MOF-assisted　strategy　to　synthesize　the　hierarchical　hollow　spherical　NiRu-C　nanohybrid　with　closely　packed　rod-like　bulges　on　the　surface.　Benefited　from　the　more　exposed　active　sites　of　NiRu-C　nanohybrid　and　the　efficient　electron/mass　transport　in　its　unique　hierarchical　hollow　spherical　nanostructure,　the　optimized　nanohybrid　showed　excellent　performance　for　alkaline　hydrogen　evolution　with　ultralow　overpotentials,　which　are　much　superior　to　those　of　Pt/C　and　the　overwhelming　majority　of　reported　electrocatalysts.　The　interpretation　of　the　reaction　mechanism　was　further　discussed　with　DFT　calculations.　Our　research　may　provide　a　guidance　for　the　development　of　advanced　electrocatalysts　with　controlled　morphology　and　excellent　performance　for　future　energy　applications.
