Claim:
1. An apparatus for activating a catalyst of a hybrid vehicle, comprising: an engine including a plurality of cylinders generating a driving torque by combustion of a fuel; at least one intake valve and at least one exhaust valve opening and closing the cylinders; a variable valve apparatus adjusting lift and opening timing of the at least one intake valve and the at least one exhaust valve; an integrated starter-generator that starts the engine and generates electrical energy by operating as a power generator with the engine in operation; a driving information detector detecting driving information including a vehicle speed, a displacement of an accelerator pedal, and a displacement of a brake pedal; an exhaust gas purification apparatus including a catalyst for purifying an exhaust gas exhausted by the at least one exhaust valve; and a controller cutting off fuel supplied into the cylinders, opening the at least one exhaust valve by using the variable valve apparatus during an intake stroke, and generating electrical energy through the integrated starter-generator when a regenerative braking condition of the hybrid vehicle is satisfied from the driving information detected by the driving information detector.
