For this purpose, the catalyst Fe₃O₄/MIL-101(Cr)@POM underwent synthesis through the co-precipitation procedure, and its structure was perfectly confirmed by various techniques such as FT-IR, XRD, FE-SEM/EDX, and ICP-OES. Following that, during tests of a three-component reaction that combines amine and alkyne compounds with an aldehyde under the A³ coupling reaction, the as-catalyst demonstrated an effectiveness profile, with the reaction conditions optimized to achieve 68.4% efficiency through a 24-h chloroform reflux procedure, whereas the solvent-free reaction route attained 64.5% efficiency, finishing in only 18 h. The reusable catalyst endured minimal degradation in activity while undergoing five cycles. Furthermore, the leaching test detected no leakage in Cu metal concentration for the filtrated solution after the catalytic reaction.

Electrospun PUiO-66 exhibits a nanostructure with nanofiber diameters in the 150–400-nm range.

The shape and homogeneity of the fibers were evaluated via SEM, while their optical properties were studied through DRS and Tauc plots, indicating a decrease in optical bandgap with high UiO-66 loading. The PUiO-66 (1%) demonstrated the maximum catalytic activity, attaining a hydrogen generating rate (HGR) of 500 mL/g<b>·</b>min, about five times higher than that of the PUiO-66 (0.2%). The photocatalytic activity significantly decreased the reaction time, demonstrating the effect of UV absorption of the PUiO-66 fibers on NaBH₄ hydrolysis. The influence of NaBH₄ concentration on hydrogen production was examined, revealing that increased reactant loading markedly enhanced the reaction rate and decreased time for the hydrolysis.

The optimum ZIF-8@Bi₇O₉I₃ nanocomposite achieved 96.12% degradation of sulfonamide after 180 min.
