Described herein is an electrochemical process to improve the yields obtained while converting ethane to ethylene with high yield, which utilizes CO.sub.2 to make CO concurrently, while solving the low conversion, low selectivity, and catalyst coking challenges for conversion ethane to ethylene currently present in the petrochemical industry.

The compact devices with built-in power can be constructed for producing disinfectants that can impart hygiene and sterilization to the device users. The disinfectants may include ozone (O.sub.3), hydrogen peroxide (H.sub.2O.sub.2), peroxone (H.sub.2O.sub.3), singlet oxygen (O), hydroxy radical (.OH) and hydroperoxyl radical (HO.sub.2.). In the electrolysis, the anode generates O.sub.2 and O.sub.3, whereas the cathode products, namely, either hydrogen gas (H.sub.2) or H.sub.2O.sub.2, is dependent on the cathode materials utilized. When SS304 is used as the cathode, H.sub.2 will be generated. On the other hand, H.sub.2O.sub.2 is formed on using cobalt oxide plated on carbon nanofilm coated Ti (Co.sub.3O.sub.4-CNF/Ti) as cathode. On using the latter, O.sub.3 & H.sub.2O.sub.2 can be electrocatalytically cogenerated. When H.sub.2O.sub.2 mixes with O.sub.3, H.sub.2O.sub.3 will be formed, so are .OH and HO.sub.2.. O.sub.3 and H.sub.2O.sub.2 can not only contribute O.sub.2 to help human beings' breathing, they can impart human beings good health as well.
