Catalytic Oxidation of Formaldehyde by Metal Pd Nanotubes Under the support of the "Hundred Talents Program" of the Chinese Academy of Sciences and the National Natural Science Foundation of China, the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences Energy and Environment Nanocatalytic Materials Research Group has made new progress in the field of efficient room temperature catalytic oxidation of formaldehyde. Formaldehyde is the main organic pollutant that affects human health at present, causing great harm to human health. The formaldehyde elimination techniques currently reported mainly focus on the indoor low-concentration (ppm-level) gaseous formaldehyde adsorption and catalytic oxidation, and these conventional techniques are difficult to meet the elimination of oxidation of high concentrations of formaldehyde in industrial wastewater. In addition, the currently reported catalytic oxidation technology completely oxidizes formaldehyde to CO2 and water, which is not conducive to the secondary rational use of formaldehyde. Moreover, the degradation product CO2 is the main component of greenhouse gases in the atmosphere, and its strong greenhouse effect is not conducive to the sustainable development of today's society. Therefore, the development of a new type of formaldehyde selective catalytic oxidation technology for the elimination of air and industrial wastewater formaldehyde and its secondary use has become an urgent scientific problem to be solved. Under the guidance of Professor Bi Yingpu, the research team used hollow Pd nanotubes as a catalyst to efficiently and selectively oxidize high-concentration aqueous formaldehyde solutions to prepare clean energy—hydrogen—based on previous research work. The hydrogen production rate can be maximized. Up to 170ml.min-1. This selective oxidation catalytic reaction system is applicable not only to formaldehyde systems but also to other organic aldehydes such as acetaldehyde, propionaldehyde, butyraldehyde, and benzaldehyde, etc., and is subjected to room-temperature selective catalytic oxidation to prepare hydrogen gas, and thus it is catalytically oxidized in organic aldehydes. Elimination and preparation of clean energy Hydrogen has a high degree of versatility and practicality. The results of this study have certain guiding significance for the development of new and highly efficient catalysts for the oxidation of organic aldehyde pollutants.
