The invention discloses a Ni-Cu/AC catalyst for preparing gas fuel through hydrothermal conversion of indole and derivatives thereof and a preparation method of the Ni-Cu/AC catalyst, and the preparation method comprises the following steps: dissolving nickel nitrate hexahydrate and copper nitrate trihydrate in water to prepare a solution A; adding activated carbon into the solution A, fully stirring and mixing, then drying to ensure that moisture is fully volatilized, and grinding to obtain powder B; calcining the powder B to decompose nitrate into oxide, and then naturally cooling to room temperature to prepare powder C; and reducing the powder C by using H2 to prepare the Ni-Cu/AC catalyst for preparing gas fuel by hydrothermal conversion of indole and derivatives thereof. According to the invention, high-efficiency conversion of indole and derivatives thereof can be realized at a relatively low temperature, high combustible gas yield is realized, and the supercritical water gasification cost of indole and
