“…It is also an easily reproducible and one-step method. The main disadvantages of this method are the long reaction time, the use of large amounts of solvents, often toxic, and the formation of by-products [60,130]. Examples of metal-organic frameworks synthesized by the solvothermal method include MOF-5 [131], MOF-74 [132],…”

In recent years, the number of materials used as drug delivery systems (DDS) has increased dramatically. The widespread use of DDSs has improved both the safety and efficacy of therapy. The systems currently in use pose numerous drawbacks and require proper improvements. Although many modern materials are being developed, metal-organic frameworks (MOFs) deserve special attention. Thermal and chemical stability, high specific surface area, low toxicity, high biocompatibility, and great potential for modification are the main features enabling MOFs to be used as DDS. In this review, we describe MOFs, their structure, synthesis, and characterization, as well as drug loading, drug release kinetics, and bioassays. A critical approach is to outline the disadvantages as well as the limitations of MOFs and to identify areas that need to be studied more thoroughly. Nonetheless, the prospective nature of MOFs as DDS and potential adsorbents in overdose or poisoning is presented and highlighted.

“…MOFs are synthesized via coordination interactions between organic linkers and metal ions (Figure 2). [104] Depending on requirements, post‐synthetic modifications (PSM) can be employed via different strategies, as depicted in Figure 3 a–c [105] . For modification of MOFs properties, a variety of PSM approaches have been developed such as covalent PSM (Figure 3a), dative PSM (Figure 3b), and post‐synthetic deprotection (PSD) (Figure 3C).…”

Owing to the abundance of availability, low cost, and environmental‐friendliness, biomass waste could serve as a prospective renewable source for value‐added chemicals. Nevertheless, biomass conversion into chemicals is quite challenging due to the heterogeneous nature of biomass waste. Biomass‐derived chemicals are appealing sustainable solutions that can reduce the dependency on existing petroleum‐based production. Metal‐organic frameworks (MOFs)‐based catalysts and their composite materials have attracted considerable amounts of interest in biomass conversion applications recently because of their interesting physical and chemical characteristics. Due to their tunability, the catalytic activity and selectivity of MOF‐based catalyst/composite materials can be tailored by functionalizing them with a variety of functional groups to enhance biomass conversion efficiency. This review focuses on the catalytic transformation of lignocellulosic biomass into value‐added chemicals by employing MOF‐based catalyst/composite materials. The main focus is given to the production of the platform chemicals HMF and Furfural from the corresponding (hemi)cellulosic biomass, due to their versatility as intermediates for the production of various biobased chemicals and fuels. The effects of different experimental parameters on the conversion of biomass by MOF‐based catalysts are also included. Finally, current challenges and perspectives of biomass conversion into chemicals by MOF‐based catalysts are highlighted.

“…PET is a synthetic molecule that belongs to the polyester polymer family. It is known for its strength and rigidity [9][10]. The abundance of PET-based waste makes it a viable source for obtaining organic linkers, such as terephthalic acid (BDC), through the depolymerization process [11,12].…”

The increasing of PET plastic waste causes various environmental problems because decomposing it is difficult to compose. This study aims to utilize PET plastic waste as a source of terephthalic acid organic linker in the solvothermal synthesis of Cu-1,4-Benzene Dicarboxylate metal-organic frameworks (Cu-BDC MOFs). Cu-BDC MOFs were characterized using FTIR, XRD, and SEM-EDX. The characterization results showed that the crystals of Cu-BDC MOFs had an irregular cubic morphology with an average crystal size of 67.96 nm. Furthermore, Cu-BDC MOFs were applied as catalysts for the esterification reaction to produce biodiesel from coconut oil. The conversion percentage of free fatty acids in the esterification process was 43.75 %, while in the transesterification process, it was 68.90 %. Analysis using GC-MS showed the presence of 8 peaks, with the largest percentage of areas identified as fatty acid methyl esters. The major components were methyl laurate (31.17 %), methyl myristate (18.77 %), methyl palmitate (12.50 %), methyl caprylate (10.76 %), methyl elaidate (10.07 %), methyl caprate (7.34 %), methyl stearate (5.67 %), and methyl linoleate (2.26 %). The quality of the biodiesel was tested, and the results were as follows: The density parameter was measured at 842.5 kg/m3, the viscosity measurement showed 2.9572 cSt, and the water content was found to be 0.09 %. Additionally, the acid number parameter was determined to be 0.2799 mg-KOH/g. HIGHLIGHTS Cu-BDC MOFs are produced through the hydrolysis of PET waste using a solvothermal mixture of distilled water, ethanol, and DMF at 85 °C for 24 h. The micrograph of the synthesized Cu-BDC MOFs reveals a clustered topography of Cu-BDC MOFs crystals with irregular cubic (hexahedral) shapes. FTIR analysis of biodiesel displays distinctive peaks corresponding to the -C-H, -C=O, -CH2, -CH3, and -C-O functional groups. The GC-MS analysis of biodiesel from coconut oil shows the presence of 8 major peaks, namely methyl caprylate, methyl caprate, methyl laurate, methyl myristate, methyl palmitate, methyl linoleate, methyl elaidate, and methyl stearate, with the largest percent area. The quality test results of biodiesel indicate a density parameter of 842.5 kg/m3, a biodiesel viscosity measurement of 2.9572 cSt, a water content of 0.0898 %, and an acid number of 0.2799 mg-KOH/g.
