A template-free method of preparing zeolites from biomass can include using rice husk ash waste material as a precursor material. The zeolites can include ZSM-5 zeolites, such as, hierarchical pure zeolites and metal-loaded (Cu, Ni) ZSM-5 zeolites. This method allows for production of zeolites in a low cost and environmentally friendly manner. These ZSM-5 zeolites may be used for numerous applications, including killing cancer cells. The cancer cells may be human lung cancer cells.

The method of making a porous carbon electrode is a chemical activation-based method of making a porous nanocarbon electrode for supercapacitors and the like. Recycled jackfruit () peel waste is used as a precursor carbon source for producing the porous nanocarbon. A volume of jackfruit () peel is collected, dried and then heated under vacuum to produce precursor carbon. The precursor carbon is mixed with phosphoric acid (HPO) to form a mixture, which is then stirred, dried and heated to yield porous nanocarbon. The porous nanocarbon is mixed with a binder, such as poly(vinylidenedifluoride), acetylene black, and an organic solvent, such as n-methyl pyrrolidinone, to form a paste. This paste is then coated on a strip of nickel foil to form the porous carbon electrode.
