摘要
报道了曙红、氯铂酸钾、氧化石墨烯和三乙醇胺混合物悬浮体系在可见光照射条件下将钾嬗变为钙的现象.在大于440 nm光照的条件下,反应体系可以产生大量的氢气,同时体系中的部分钾原子转变为钙元子.在反应过程中,悬浮混合物中的钙元素浓度持续增加,同时伴随发生质子的还原为氢和部分质子反应为氦3和氦4的反应.分析表明,在自然界的某种环境和条件下,钙有可能通过在温和条件下的低能核反应(LENR)经历钾的嬗变生成,这个过程可能与光催化产氢过程中生成的负氢有关.
This work reported experimental evidences of stable potassium isotopes transmutation to calcium during photocata- lytic hydrogen evolution in water mixture dispersion of dye (Eosin Y), potassium chloroplatinate (KEPtC16 ), graphene oxide and triethanolamine (TEOA) driven by visible light. This reaction mixture can produce significant amount of hydrogen under irradiation of light with wavelength longer than 440nm, meanwhile, partial potassium nuclei are continuously converted into calcium nuclei. The concentration increase of calcium element in the mixture dispersion is accompanied with the process of proton reduction (H2 evolution) and proton nuclear reaction which yields 3He and 4He. Those results indicate that some of calcium elements in nature might originate from potassium-calcium transmutation through low energy nuclear reaction (LENR) under very mild conditions, which might be related to the yield of negative hydrogen ( H- ) during photocatalytic hydrogen generation.
