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,...

AI Technical Summary

Problems solved by technology

Under the action of catalyst, formic acid can generate the required hydrogen and carbon dioxide (HCOOH→H 2 +CO 2 ); it is also possible to generate water and carbon monoxide (HCOOH→H 2 O+CO), but the generated CO is easy to poison and deactivate the catalyst, so the reaction must be strictly controlled
