The composites are characterized by sorts of evaluation methods, and their capacities for removal of methyl mercaptan and hydrogen sulfide from natural gas are evaluated. The results show that copper nanoclusters are successfully loaded on MOF-199, and the morphology and crystal structure of the modified MOF-199 do not change significantly compared with pure MOF-199. However, the type of solvent and the content of copper nanoclusters affect the specific surface area and pore size of MOF-199. The highest specific surface area of 1177 m2 g−1 is reached when 0.24-wt% copper nanoclusters are loaded on MOF-199 in H2O. This sample presents a total pore volume of 0.58 cm3 g−1, an average pore size of 2.01 nm, and the highest breakthrough capacities for H2S (41.25 mg g−1) and CH3SH (71.42 mg g−1), which are 33.75% and 65.59% higher than that of pure MOF-199, respectively.

Comprehensive analysis using techniques such as TGA, EDX, XRD, SEM, and FTIR confirmed the successful formation of uniformly dispersed Ag₂O nanoparticles within the chitosan matrix. The interaction between silver oxide and the active sites of chitosan was crucial in achieving this stable composite structure. Our findings revealed that the dielectric permittivity of the nanocomposites decreases with increasing frequency, particularly in samples with higher Ag₂O content, because of Maxwell–Wagner–Sillars interfacial polarization. Furthermore, the electric modulus analysis indicated reduced electrode polarization and enhanced α-relaxation with increased Ag₂O, suggesting improved performance in frequency-dependent applications. The conductivity behavior, characterized by a power-law dependence on frequency, aligns with the correlated barrier hopping model of charge transport. Density functional theory (DFT) calculations supported the experimental results, highlighting the stability and enhanced reactivity of the Ag₂O/CS composite compared with pure chitosan.

XRD, Raman, FT-IR, and XPS tests showed that the UU 200/Bi4O8 nanocomposite was successfully formed. The SEM and TEM images revealed that the UU 200/Bi4O8 nanocomposite exhibits a mixed rod and spherical structure. The supercapacitor performance of pure UU 200 and UU 200/Bi4O8 nanocomposite has been examined through cyclic voltammetry (CV), galvanostatic charge–discharge (GCD), and electrochemical impedance (EIS) measurements. Interestingly, the UU 200/Bi4O8 nanocomposite delivered a maximum specific capacitance value of 220 F g−1 at 1 A g−1. Furthermore, the UU 200/Bi4O8 nanocomposite potential was extended beyond its energy storage capability to the electrocatalytic HER process. The electrocatalytic HER performances were assessed through linear sweep voltammetry (LSV), CV, chronoamperometry (CA), and EIS analysis. The overpotential (ɳ) of 130 mV and the Tafel slope value of 131 mV dec−1 indicate the UU 200/Bi4O8 nanocomposite supremacy in advanced applications.
