Doping Zr4+ alters the electronic properties of the support. The electronic metal–support interaction produces the upshift of d-band center of Ru nanoparticles, which further influences the catalytic activity of ammonia synthesis.
The delicate balance between dispersion and reduction of the Co-based Fischer–Tropsch synthesis catalyst is the golden key to enhancing catalytic performance, which highly depends on an optimized metal–support interaction. In...
