Abstract The influence of Ni2P loading on the properties of Ni2P/SiO2 catalysts was investigated by means of N2 adsorption–desorption, X-ray diffraction, H2 and NH3 temperature-programmed desorption, CO chemisorption, inductively coupled plasma atomic emission spectroscopy and activity evaluation for the hydrodechlorization of chlorobenzene. It was found that increasing Ni2P loading resul…
