Chemical analysis of photocatalytic membrane (FTIR, XRD, UV-vis/optical, XPS, and zeta potential)

The photocatalytic membrane reactor offers the potential for the decontamination of organic pollutants, reduction of heavy metals through photocatalysis, inhibition of bacterial growth, and resource recovery. Researchers have explored the application of membrane principles in water purification, utilizing photocatalytic activity to enhance membrane performance. In addition to the overarching objective of developing improved photocatalytic membranes, the fabrication variables have a significant impact on the final outcomes. Evaluating the physicochemical characteristics of the membranes, such as chemical bonding, crystallinity, bandgap properties, binding energy, and photocatalyst charges, provides insights into the effects of these fabrication factors on the ultimate performance. This chapter will delve into the progress and challenges of each chemical analysis, along with the prospects for future research.
