1. A nanocomposite comprising:
(a) a plurality of transition metal oxide nanoparticles;
(b) a plurality of sheets of a first two-dimensional (2D) material, wherein at least a portion of the plurality of sheets of the first 2D material has an average sheet thickness of less than 20 nm; and
(c) a plurality of sheets of a second 2D material, wherein the second 2D material is of a different type than the first 2D material, and at least a portion of the plurality of sheets of the second 2D material has an average sheet thickness of less than 20 nm;
wherein a component weight ratio of the plurality of transition metal oxide nanoparticles,the plurality of sheets of the first 2D material, and the plurality of sheets of the second 2D material (x:y:z) is in a range from (1:0.001:0.001) to (1:0.67:1.67), where x is the plurality of transition metal oxide nanoparticles, y is the plurality of sheets of the first 2D material, and z is the plurality of sheets of the second 2D material,
wherein the plurality of transition metal oxide nanoparticles is anchored between the first 2D material and the second 2D material, and
wherein the nanocomposite further comprises 40% to 80% by total weight of the nanocomposite of sulfur.
