Preparation of value-added metal-organic frameworks (MOFs) using waste PET bottles as source of acid linker

Metal-organic frameworks (MOFs) have been considered with various novel applications and the development of cost-effective processes is essential for further practices. In this work, waste PET bottles were demonstrated as the source of acid linker to prepare value-added metal-organic frameworks UiO-66(Zr), and the texture properties as well as hydrogen storage capacity are comparable to those derived from commercial chemicals. This process offers an economically attractive strategy for eliminating waste PET stream while making value-added materials.
