This study investigates photocatalytic cells based on cocatalyst-loaded SrTiO3:Al and nano-SiO2 as a porous binder, immobilized on frosted glass. Comprehensive analysis confirmed the successful incorporation of aluminum into SrTiO3, increasing oxygen vacancy concentration and enhancing charge transfer. The deposition of RhCr2O3 and CoOOH cocatalysts significantly improved photocatalytic activity, boosting hydrogen and oxygen evolution rates to 3.8401 and 1.6319 mmol g−1 h−1, respectively. The introduction of nano-SiO2 increased hardness (0.23–0.25 GPa) and Young’s modulus (5.27–5.40 GPa), reinforcing structural integrity. The development of efficient photocatalytic panels requires a multifaceted strategy that considers chemical, mechanical, and optical properties together with stability, durability, and energy efficiency. Future research should focus on optimizing these key parameters to enhance system performance for industrial applications.
