Photocatalytic water splitting is an environmentally friendly hydrogen production method that uses abundant renewable resources such as water and sunlight. While Titanium dioxide (TiO) photocatalyst exhibits excellent properties, its high band gap limits absorption to ultraviolet (UV) irradiation, resulting in low photo conversion efficiency. This review explores various modification techniques aimed at enhancing the efficiency of TiO under visible light irradiation.

This study aimed to investigate the thermal decomposition characteristics of (CS) shells that were treated with various metal oxides (ZnO, CuO, FeO/FeO, and FeO) using pyrolysis. The study also sought to identify pyrolysis reaction parameters (kinetics and thermodynamics parameters) that are not widely documented.

- The study investigates the thermochemical properties of hard shells from fruit waste, focusing on their composition and potential as bioenergy sources.
- Intermediate pyrolysis resulted in significant weight loss (56.45 wt%) and activation energy values indicating the efficiency of different methods in characterizing thermal degradation.
- The pyrolysis process produced substantial amounts of biochar and bio-oil, both of which demonstrated high carbon content and calorific values, making them promising alternatives for bioenergy.
