The powder X-ray
diffraction (XRD) measurements were performed on a Bruker D8 Advance
X-ray diffractometer using Cu Kα radiation to identify the ZSM-5
zeolite crystalline phase. The working voltage and current were 40
kV and 40 mA. The scanning rate and range (2θ) were 5 °/min
and 5–60°. Scanning electron microscope (SEM) images of
ZSM-5 crystal seed and film morphology were inspected with a JSM-7500F
cold field emission scanning electron microscope (JEOL, Japan). The
acceleration voltage and working current were 5 kV and 20 mA. All
samples were coated with gold before measurements. The particle size
distribution of the ZSM-5 crystal seed was collected by dynamic light
scattering (DLS) mode of Nano ZSE Zetasizer (Malvern, U.K.). The N₂ adsorption–desorption isotherms at 77 K were measured
by ASAP 2460 surface area and porosity analyzer (Micromeritics), with
the aim to confirm the pore distribution of the ZSM-5 film. Before
the analysis, the film capillary sample was degassed in vacuum at
200 °C for 12 h.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
