“…Only the amorphous phase can be resolved in the XRD patterns of Ga 0.1 Al 1.9 O 3 and Ga 0.5 Al 1.5 O 3 (Figure a,b), while the XRD patterns of the Pt/Ga 0.1 Al 1.9 O 3 and Pt/Ga 0.5 Al 1.5 O 3 samples exhibit a crystallized phase of γ-Al 2 O 3 (JCPDS card no. 29-0063) as manifested in Figure c,d, implying that the addition of Pt likely benefits the crystallization of γ-Al 2 O 3 . Both the addition of HCl solution and calcination treatment could result in the structural change of metal oxides.…”

“…Metal–organic frameworks (MOFs) as a class of porous materials with well-defined crystalline structure and facilely tailored pore properties have attracted broad attention in various application fields. Thermal treatment of MOFs can produce porous derived materials such as metal oxides, carbon nanostructures, metal-based compounds, and their composites. The MOFs derivatives with large surface area, excellent stability, and tunable structures afford their extensive applications in thermocatalysis, photocatalysis, and electrocatalysis. Direct calcination of MOF precursors under air atmosphere could generate metal oxide catalysts and supports utilized in heterogeneous catalysis including oxidation reaction, hydrogenation reaction, dehydrogenation reaction, and Fischer–Tropsch synthesis. The MOF derivatives such as cobalt oxides derived from ZIF-8, Zn/Co bimetallic ZIFs, and Fe-BTC have exhibited great potential in the direct propane dehydrogenation process. Moreover, Al-based MIL-53-derived mesoporous Al 2 O 3 can be used as catalyst support in the selective hydrogenation of m -chloronitrobenzene, hydrogenolysis of furfural, and dry reformation of methane . To the best of our knowledge, the fabrication and characterization of Al-based or Ga-based MOFs derivatives for the highly efficient propane dehydrogenation reaction has not been reported so far.…”

“…The hydrogenation of halogenated nitroarenes is regarded as a crucial reaction in organic synthesis and has wide applications in medicines, insecticides, pigments, and chemical reagents. However, the traditional methods always utilize sulfurated alkali, iron powder, and hydrazine hydrate as reductants, which have caused huge environmental problems and are inconsistent with the sustainable concept of organic synthesis. , The hydrogenation reaction with H 2 as a hydrogen atom source over heterogeneous catalysts exhibits green and efficient features, which have attracted extensive attention. For instance, non-noble catalysts such as Co, Ni, and Cu have been developed for the hydrogenation of halogenated nitroarenes, attributed to their abundant reserves and low cost. However, these catalysts usually need to be used under high hydrogen pressure and high reaction temperature conditions that will consume considerable energy and pose safety risks . Noble metal catalysts such as Pt, Pd, and Ru are capable of excellent hydrogenation performance under mild reaction conditions, but the stubbornly high cost cannot satisfy their large-scale application. In addition, noble metal catalysts also exhibit imperfect selectivity because of their strong hydrodechlorination capabilities that will generate the dechlorination byproducts inevitably . Therefore, exploring effective strategies to enhance the catalytic activity and selectivity for hydrogenation of halogenated nitroarenes has become an important topic.…”
