A series of characterizations and theoretical calculations were developed to research the physicochemical properties and adsorption behaviors of the catalysts. The results demonstrated that the Zn cation defect and doping with Mo resulted in a downshift of the d-band center of ZnAl₂O₄, which not only caused the desorption of isobutene but also favored the flat adsorption orientation of isobutane.

In this work, the Fe₂Ni₁/NiFe₂O₄@NCG bifunctional catalysts are constructed by employing metal-chelated COFs and MA/GO mixture as primary precursors combined with a high-temperature pyrolysis strategy.

However, the high reaction temperatures and low production efficiency of the preparation of β-Si₃N₄ powder hinder its widespread adoption. To achieve low-temperature and efficient synthesis of β-Si₃N₄ powder, this study employed tetraethyl orthosilicate as the silicon source and glucose as the carbon source, utilizing a sol-gel process combined with a carbothermal reduction and nitridation.
