Abstract: Catalysts and methods for catalytic hydrogenolysis of a polymer. The method comprises a) activating a catalyst with a hydrogen source to provide an activated catalyst, wherein the catalyst comprises: i) a MXene support of Formula I: Mn+1XnTx (I); wherein each M is independently an early transition metal; X is carbon or nitrogen; Tx is a surface functional group wherein x is 0-10; and n is 1, 2, 3, or 4; and ii) a supported metal, wherein loading of the supported metal on the MXene support is less than 5% w/w based on the weight of the catalyst; and b) contacting a mixture of the activated catalyst, hydrogen gas, and a polymer at a temperature of at least about 200° C. for a period of time that is sufficient for catalytic hydrogenolysis of the polymer; thereby converting the polymer to a fuel.
