Converting N molecules into NH with TiO/FeO composite covered with a thin water layer under ambient condition.

As ammonia manufacture today require huge energy and very pure hydrogen gas and moreover emit large quantities of CO, researches for new ammonia synthesis methods are actively performed. Here, author reports the novel method through which N molecules in air is reduced into ammonia with TiO/FeO composite having thin water layer on composite's surface under ambient condition (less than 100 °C and atmospheric pressure). The composites were composed of both nm-sized TiO particles and μm-sized FeO ones.

Converting of CO into low-molecular-weight organic compounds with the TiO/ZrO composites under solar irradiation.

The preparation of a specially modified titanium dioxide/zirconium oxide (TiO/ZrO) composite and its subsequent application using a unique method are described. Specifically, after the whole surface of the composite was covered with a very thin layer of water, solar light was irradiated onto it. This method is unique because the reduction of CO was performed in air (gas phase).
