Abstract

Abstract: P‐doped carbon material (P−C) is successfully fabricated through directly combust phytic acid via microwave assistant. Then the as‐made P−C is selected as the support to load various amount of Ni. As the evaluated results show that 5 %Ni/P−C exhibits better catalytic performance than 5 %Ni/C for chlorodifluoromethane hydrodechlorination (HDC) reaction. It is because that the doped‐P is feasible to promote the dispersion of Ni species on the surface of P−C through the strong interaction between Ni and the P−C support. Therefore, combining the synergetic effect between Ni and heteroatom‐doped carbon could provide a promising way to improve the activity of HDC reaction. Abstract : P‐doped carbon material (P−C) is successfully fabricated through directly combust phytic acid via microwave assistant. The as‐made P−C is selected as the support to load various amount of Ni. 5 % Ni/P−C catalyst exhibited better HDC activity (> 31 %) as well as the selectivity to HFC‐32 (>80 %) than 5 %Ni/C, within the time region, which was due to the doped‐P is feasible to promote the dispersion of Ni species through the strong interaction between Ni and the P−C support.
