摘要： Disclosed is a method for preparing a metal catalyst composite. The method includes pre-treating a carbon support in a reactor, and depositing a metal precursor on the pre-treated carbon support. The pre-treating the carbon support may include exposing the carbon support to a nucleating agent, for example, titanium tetrachloride (TiCl4), silicon tetrachloride (SiCl4) and carbon tetrachloride (CCl4).

摘要： A gas sensor includes a positive electrode of a carbon material and a negative electrode. The gas sensor further includes an insulation substrate, where the positive electrode and the negative electrode are attached to the insulation substrate, and surfaces of the positive electrode and the negative electrode and a surface of a portion of the insulation substrate between the positive electrode and the negative electrode are coated with a hygroscopic salt. The gas sensor may maintain moisture on the surface of the sensor electrode without using a separate external moisture supply device and may sense a gas with a high sensitivity even without using a high-priced catalyst metal or a high-temperature reaction.
