Shape effect of Ag–Ni binary nanoparticles on catalytic hydrogenation aided by surface plasmons†
Abstract
Ag–Ni binary nanoparticles with different shapes (snowman and core–shell) were synthesized by modulating the lattice strain. In the catalytic hydrogenation of 4-nitrophenol, a significant enhancement of the reaction rate was observed for the snowman shape in comparison with the core–shell shape under light irradiation.
