A method of manufacturing a catalyst includes mechanochemically processing an input material to generate a processed material, where the input material comprises a support and loading the processed material with a loading material. The support is a zeolite, a Beta zeolite, or a H-Beta zeolite and the loading material comprises nickel (Ni) or nickel-copper (NiCu). Lanthanum oxide (LaO) is a promoter for the catalyst. A first interface of a NiCu/La-zeolite catalyst is generated when the loading material further includes the promoter; and a second interface of a NiCu/La-zeolite catalyst is generated when the input material further includes the promoter.

Provided herein is a triboelectric nanogenerator comprising a substrate layer; an electrode layer; and a tribolayer; wherein the electrode layer and the tribolayer are bonded to each other by hydrogen bonds. Also provided herein is a biopolymer-based triboelectric nanogenerator, comprising a first component having a positive tribolayer; and a second component having a negative tribolayer, wherein each of the first component and the second component comprise a substrate layer; an electrode layer; and a tribolayer; wherein the electrode layer and the tribolayer of the first component are bonded by hydrogen bonds. Further provided herein is a method of making a biopolymer-based triboelectric nanogenerator.
