Polymer-Based Nanomaterials To Use in Hydrogen Acquisition and Hydrogen Energy Storage

Abstract

Energy demand has increased dramatically worldwide due to population growth. This is because almost all activities take place through energy. The majority of the energy used is derived from fossil sources. The use of fossil-based energy causes pollution to the environment and these resources cannot be recycled. Compared to renewable energy sources, fossil-source energy sources are much cheaper but they increase environmental pollution. Among renewable energy sources, hydrogen is seen as a highly effective resource. With the combustion of hydrogen, there are no chemicals that can be harmful to the environment, and its energy capacity is higher than other energy sources. Numerous studies have been carried out as an alternative to conventional storage methods for the safe storage of hydrogen. In this context, many studies have been carried out by scientists to develop new chemical hydrogen storage materials and to prepare and identify new heterogeneous catalyst systems that produce hydrogen from these materials. Hydrogen can be obtained from various materials such as formic acid and amine-borane (ammonia-borane, methylamine-borane, dimethylamine-borane, and hydrazine borane) compounds in liquid and solid form have a very important place. To release hydrogen from these materials, generally, some suitable catalysts are used. Catalysts are prepared using supporting materials like carbon and carbon derivations with different preparation methods to obtain high catalytic activity catalysts. In this chapter, nanomaterials composed of carbon and carbon derivations as catalysts to obtain hydrogen from hydrogen sources are evaluated. © 2021 Elsevier Inc. All rights reserved.
