摘要： PROBLEM TO BE SOLVED: To manufacture efficiently SnO
2 having noble metal nanoparticles carried thereon.
SOLUTION: A chelate compound equipped with at least two ligands coordinated into SnO
2 and at least two ligands coordinated into a noble metal is added to hydrosol of SnO
2 , to thereby coordinate the chelate compound into SnO
2 sol, wherein noble metal nanoparticles in which an organic compound is coordinated are dispersed in an organic dispersant is brought into contact with the hydrosol of SnO
2 in which the chelate compound is coordinated, to thereby coordinate the chelate compound into the noble metal nanoparticles; thereby the noble metal nanoparticles are carried on SnO
2 particles in the sol; and the calcination is performed to acquire an SnO
2 gas sensor. The noble metal nanoparticles can be carried efficiently on SnO
2 .

摘要： PROBLEM TO BE SOLVED: To provide a VOCs sensor capable of selectively detecting VOCx gas from propane, hydrogen, and CO. SOLUTION: A heat-resistant insulating substrate 4 is provided with a BiMeVOx film 6, a detection pole 8, and a reference pole 9, and the reference pole 9 is covered with a catalyst film 10. The detection pole 8 and the reference pole 9 are produced by mixing BiMeVOx into perovskite of La0.6Sr0.4Co0.8Fe0.2O3 or the like for facilitating the adsorption/desorption of oxygen.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a gas sensor highly sensitive to VOC and capable of providing SnO
2 nano crystal whose crystallite diameter is small even after film formation as the gas sensor and whose crystal growth is gradual.
SOLUTION: An organic compound of tin is dissolved together with a surfactant in an organic solvent, and heated to thermally decompose the organic compound of tin. This causes the surfactant to be adsorbed or coordinated to the surface of the SnO
2 nano crystal to disperse the SnO
2 nano crystal in the organic solvent while preventing its crystal growth in firing, thereby providing the gas sensor highly sensitive to VOC.

摘要翻译：要解决的问题：提供一种制造对VOC高度敏感的气体传感器的方法，并且能够提供即使成膜后的微晶直径也较小的SnO 2 SBS纳米晶体作为气体传感器，其晶体生长是渐进的。解决方案：将锡的有机化合物与表面活性剂一起溶解在有机溶剂中，并加热以使锡的有机化合物热分解。这使得表面活性剂被吸附或配合到SnO 2 SBB纳米晶体的表面上，以将SnO SBM 2纳米晶体分散在有机溶剂中，同时防止其在晶体生长中的晶体生长，从而提供对VOC高度敏感的气体传感器。版权所有（C）2011，JPO＆INPIT
