The hybrid semiconducter-macrocycle catalyst TiO2-cobalt phthalocyanine promotes the solar photolysis of aqueous bromoform under anaerobic conditions. The major decomposition products are dibromoethane and HBr. Bromomethane and methane were produced only after prolonged photolysis (30 hr). Acetone, derived from added 2-propanol, was the only observed oxidation product. Preliminary experiments showed that electrolytic reduction of aqueous carbon tetrachloride at a vitamin B12-modified silver electrode produced the expected lower homologues but with surprisingly high yields of methane.
混合半导体-大环催化剂TiO₂-钴酞菁在厌氧条件下促进溴仿水溶液的太阳光光解。主要分解产物是二溴乙烷和HBr。仅在长时间光解(30小时)后才产生溴甲烷和甲烷。来自添加的2-丙醇的丙酮是唯一观察到的氧化产物。初步实验表明,在维生素B₁₂修饰的银电极上对四氯化碳水溶液进行电解还原产生了预期的低级同系物,但甲烷的产率出奇地高。
