• Pt–Ni bonded Pt single-atom (SA) catalyst, rather than classic Pt–O bonded SA catalyst, was successfully constructed.

• The electronic states of Pt SA catalyst were deeply regulated and negatively charged Pt^δ− was realized.

• Pt–Ni bonded Pt SA catalyst-enhanced absorbability for activated hydrogen atoms and promoted hydrogen absorption.
