A new method of hydrogen generation from water, by irradiation with CW infrared laser diode of graphene scaffold immersed in solution, is reported. Hydrogen production was extremely efficient upon admixing NaCl into water. The efficiency of hydrogen production increased exponentially with laser power. It was shown that hydrogen production was highly efficient when the intense white light emission induced by laser irradiation of graphene foam was occurring. The mechanism of laser-induced dissociation of water is discussed. It was found that hydrogen production was extremely high, at about 80%, and assisted by a small emission of O, CO and CO gases.
报道了一种通过用连续波红外激光二极管照射浸入溶液中的石墨烯支架从水中制氢的新方法。将氯化钠混入水中时，产氢效率极高。产氢效率随激光功率呈指数增长。结果表明，当石墨烯泡沫受激光照射产生强烈白光发射时，产氢效率很高。讨论了激光诱导水分解的机理。发现产氢率极高，约为80%，且有少量氧气、一氧化碳和二氧化碳气体排放辅助。
