%X The
hydrogen evolution reaction (HER) and electronic properties
of single-layered TiO2 nanosheets effectively modulated
by transition-metal doping and biaxial strain were investigated in
this work. Surprisingly, the hydrogen adsorption free energy of Cr-doped
LNS-TiO2 nanosheets was reduced to almost 0 eV, which is
comparable to the well-known highly efficient catalyst of Pt metal.
The tunable hydrogen adsorption ability was correlated with the O-2pz band center level. Moreover, by upshifting
the pz band center level, both the tensile
and compressive strains could decrease the hydrogen adsorption free
energy of V-doped LNS-TiO2 nanosheets, even close to 0
eV with 7% tensile strain. These insights open a new avenue into realizing
high HER activity in oxide nanosheets.
