Tribo-Catalytic Conversions of H2O and CO2 by NiO Particles in Reactors with Plastic and Metallic Coatings

NiO has been found to be highly outstanding in producing H2 and O2 from H2O through magnetic stirring, while its capability for the reduction of CO2 mechanical stimulation not investigated. Presently, particles have employed promote conversion enclosed reactors into flammable gases stirring. For a 150 mL glass reactor filled with 50 water, 1.00 g particles, 1 atm CO2, 24 h stirring using home-made Teflon rotary disk resulted formation 33.80 ppm CO, 10.10 CH4, 12,868.80 H2. More importantly, was substantially enhanced coating some polymers metals on bottoms, including 25.64 CO 70.97 CH4 obtained PVC-coated 30.68 52.78 3.82 C2H6, 2.18 C2H4 stainless steel-coated reactor. Hydroxyl radicals were detected fluorescence spectroscopy under water. A tribo-catalytic mechanism proposed by that is based excitation electron-hole pairs energy absorbed friction. These findings only reveal great potential utilized but are also valuable fundamental studies.
