Abstract

The invention relates to a functionalized carbon nanotube loaded palladium nano-catalyst and preparation and application of the functionalized carbon nanotube loaded palladium nano-catalyst. The functionalized carbon nanotube loaded palladium nano-catalyst is characterized in that the functionalized carbon nanotube loaded palladium nano-catalyst is synthesized through a one-step rapid reduction method, and the application of the functionalized carbon nanotube loaded palladium nano-catalyst to preparation of hydrogen by catalyzing an aqueous solution of formic acid. The functionalized carbon nanotube loaded palladium nano-catalyst has the beneficial effects that the functionalized carbon nanotube loaded palladium nano-catalyst is synthesized through the one-step rapid reduction method at the room temperature, the functionalized carbon nanotube loaded palladium nano-catalyst has the advantages of short synthesis time, convenient operation and the like, the dispersity of palladium NPs onan F-CNTS substrate is obviously improved, and the particle size of the metal NPs is reduced; the synthesized Pd/F-CNTS catalyst is used to catalyze the aqueous solution of formic acid to decompose and make hydrogen at the room temperature, and the catalyst still keeps very high catalytic activity, 100% conversion rate, 100% hydrogen selectivity and better cycling stability without any additive.

Description

technical field [0001] The invention belongs to the field of catalyst preparation and the sustainable development of environment and energy, and in particular relates to a -NH 2 Preparation of functionalized carbon nanotube-supported palladium nanocatalyst and its application in hydrogen production from formic acid hydrolysis. Background technique [0002] Hydrogen energy, as an abundant, renewable, and pollution-free energy source, can be widely used in power generation and fuel cells, and is considered to be a very potential energy carrier for transportation and power generation applications. However, traditional high-pressure tanks and low-temperature liquid hydrogen storage methods have disadvantages such as low efficiency, poor safety, and high cost. Therefore, the development of safe and efficient hydrogen storage methods is a current research hotspot. [0003] Formic acid (HCOOH, FA) is rich in sources, has high energy density, is a stable liquid at room temperature,...
