The structural, morphological, and optical properties were determined from X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), and UV-Vis spectroscopy. The microstructure and crystallite size of NCs were observed as hexagonal perovskite structures in the 23.4 - 20.1 nm range.

Structurally, ZnO exists in three different forms: rocksalt, cubic blende, and hexagonal wurtzite. It has been reported that the wurtzite structure produces more H₂ compared to its counterparts. Herein, we discuss several techniques for synthesizing zinc oxide and how incorporating zinc oxide nanoparticles with metal oxides, sulfides, and other materials can enhance its performance in the visible light region. Recently, integrating ZnO with TiO₂ –Ag using an S-scheme heterostructure boosted the H₂ activity rate to approximately 60.0 mmol/g/h, which is about 166 times superior to pristine ZnO.

The review breaks down modification techniques into chemical and physical processes. Important physical changes covered include preactivation, carbonization, and using fluidized bed technologies and rotary kilns. It has been shown that these methods greatly improve the surface properties of neem biomass, which makes it better at absorbing things and holding more. The changes that were made also have an effect on the adsorption kinetics and isotherms, which helps us understand the adsorption rates and equilibrium behaviors of the changed adsorbents better. Neem biomass adsorbents are illustrated through their versatility and efficacy in the removal of organic pollutants, dyes, and heavy metals from effluent. This is illustrated through specific applications. Additionally, computational studies and artificial intelligence are looked into to see if they can help us understand how adsorption works at the molecular level, improve the efficiency of modification processes, and guess how adsorption will behave.
