Efficient energy storage from intermittent renewables can rely on the conversion of temporary excess by alkaline electrolysis, yielding oxygen and green hydrogen, which be stored used demand. Electrodes made laser-induced graphene (LIG) materials offer many advantages over traditional processing routes, due to inherent simplicity low cost-benefit. Despite poorly studied, LIG electrodes are promising for water splitting when properly doped/modified with metals. However, proper design...
Zinc oxide (ZnO)/laser-induced graphene (LIG) composites were prepared by mixing ZnO, grown laser-assisted flow deposition, with LIG produced laser irradiation of a polyimide, both in ambient conditions. Different ZnO:LIG ratios used to infer the effect this combination on overall composite behavior. The optical properties, assessed photoluminescence (PL), showed an intensity increase excitonic-related recombination increasing amounts, along reduction visible emission band. Charge-transfer...
