A method of making a zeolite with encapsulated platinum is provided. The method includes dissolving an aluminum source in water to form a first solution, dissolving a hydroxide in water to form a second solution, dissolving a templating agent in water to form a third solution, and adding a silica source to the first solution to form a fourth solution. The method further includes adding the second solution to the fourth solution to form a fifth solution, adding the third solution to the fifth solution to form a sixth solution, and adding a platinum source to the sixth solution. The sixth solution is crystallized to form a solid product, which is recovered. The solid product is calcined. An ammonium ion exchange is performed on the solid product to form a second solid product, and the second solid product is calcined.
