Recently, due to energy shortages and environmental pollution caused by the continued use of fossil fuels, there is a growing need for renewable sources replace fuels. ZIF-67 has porous structure, large surface area, high thermal chemical stability, narrow band gap, so it highly useful as photocatalyst. In this study, CoM-ZIF/CdS photocatalyst based was synthesized using precipitation method synthesis with four different substances: Ni, Zn, Sn, Cu. Field emission scanning electron microscopy analysis revealed that leaf-like particles are formed, dispersive X-ray spectrometer confirmed CdS exists on surface, further evidenced diffractometer analysis. The wurtzite found in optimized sample considered source higher photocatalytic activity. photoelectron spectroscopy detects all elements included photocatalyst, prominent peaks Cd S surface. UV-vis used analyze light absorbance. gap changed various transition metals because metal alters level conduction band. CoNi-ZIF/CdS exhibited highest hydrogen production rate 1192.9 µmol/g/h, reproducibility. heterojunction between Co-ZIF reduces recombination. conclusion, results an efficient charge separation mechanism.

In this study, new composite materials comprising zeolitic imidazolate framework (ZIF) structures and microchannel glass (MCG) plates were fabricated using the hydrothermal method their morphological spectral properties investigated XRD, SEM, FTIR, Raman spectroscopy. XRD studies of powder samples revealed presence an additional phase for a ZIF-8 sample, whereas ZIF-67 samples, which prepared through two different chemical routes, showed no phases. A detailed analysis FTIR micro-Raman spectra formation stable ZIF inside macropores MCG substrate. The hydrophilic nature substrate its interaction with structure resulted in ZIF-MCG composites. We believe that these may find wide range important applications field sensors, molecular sieving.
