Activated carbon (AC) and hydroxyapatite (HAp) composite were successfully prepared via mechanical mixing and exhibited
a crushed snack-like morphology compared to the well-defined pore structure of pure AC. The purpose of this research
was to explore the potential of AC/HAp for the degradation of methylene blue (MB) dye and hydrogen production. Despite
the morphological changes, AC and AC/HAp achieved a high MB degradation rate (92.75 and 82.05) % under sunlight, at
a temperature of 26.24 °C and pH of 4.18, and showed optimum hydrogen production (3579 mol/g.h). These performances
are suspected from the decrease in crystallite size and narrowed Δ(LO − TO) and confirmed by image processing results
with RBG enhancement showing more light transmitted by the solution. Increasing in 2 indicates the potential for improved
light interaction. IoT-enabled real-time monitoring system demonstrates its efficacy in facilitating wastewater treatment and
hydrogen production, offering a promising solution for aquatic ecosystem restoration.
