摘要:A one-pot synthesis of Nb 5+ -doped TiO 2 nanoparticles (NPs) with low cost and high efficiency for dye sensitized solar cells (DSSCs) is disclosed in the present invention. The Nb 5+ -doped TiO 2 NPs with Nb dopants of 0Ëœ5 mol % are prepared by directly mixing TiO 2 slurry with Nb 2 O 5 gel obtained by UV treatment of a mixture of NbCl 5 powder, ethanol and water in a certain ratio, following by heat treatment without using hydrothermal method. The as-prepared NPs exhibit well-crystallized pure anatase TiO 2 phase with uniform particle distribution. The incorporation of Nb 5+ leads to a stronger and broader light absorption in visible light range and a decrease of band gap with increasing Nb dopant content, which enhances the efficiencies of light-harvesting and electron injection and suppresses the charge recombination. The present method provides a simple and cost-effective mass-production route to synthesize n-type metallic ion doped TiO 2 nanoparticles as excellent photoanode materials.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.

摘要:[Problem] The present invention addresses the problem of increasing the rate of reaction by controlling ammonium ions, which are generated by ammonia as the objective of the electrolytic synthesis of ammonia and protons that are supplied to the cathode, by means of the cathode and the cathode catalyst layer. [Solution] The present invention provides a gas diffusion electrode which is integrated with a catalyst layer that uses a material selected from the group consisting of cathode catalyst layer materials. Examples of the cathode catalyst layer materials include a fired body and an ionic liquid.
