Abstract: Techniques may relate to an electrode having high production efficiency of a synthetic gas containing at least CO. Such techniques relating to an electrode may include: a catalyst that produces at least carbon monoxide by a reduction reaction; an electrode material including the catalyst; and a solid base additive provided at least on the electrode material.

Abstract: An ion recovery device including an ion selective permeable membrane with an ion conductive layer containing a lithium ion conductor formed of an inorganic substance, and a support layer is formed of a porous body wherein the ion selective permeable membrane has a configuration (I). In configuration (I) the ion conductive layer is provided in contact with one principal surface side of a support layer, and an electrode is provided in contact with another principal surface side opposite to the one principal surface side on which the ion conductive layer is provided.

Abstract: A technique may produce a composite at a low temperature by a reducing agent that is easy to handle. A technique may produce a composite in which a metal simple substance or a metal oxide derived from reduced cations, or both of them are supported on a carrier. The technique may include at least: preparing a liquid phase mixture containing at least an alcohol compound as a first reducing agent, a phosphinic acid or a salt thereof as a second reducing agent, the carrier, and a source compound of one or more cations selected including Au, Ag, Cu, Pt, Rh, Ru, Re, Pd, and/or Ir; and reducing the cations in the liquid phase mixture.
