This work investigates the development, characterization, and evaluation of nanostructured catalysts intended especially for environmentally benign energy conversion. We developed nanostructured catalysts by modifying the sol-gel method and varying the precursor material and reaction conditions ratios. The morphological differences between the synthesised catalysts were shown. Among catalyst 3's best features were its large surface area and pore volume. Noteworthy activity and selectivity were shown by catalyst 3. Low overpotential was attained along with high current density and faradaic efficiency. The stability studies proved that Catalyst 3 was durable since, over many cycles, its electrochemical performance scarcely altered. The requirement of carefully adjusting the synthesis conditions to tailor nanostructured catalysts for specific energy conversion applications is highlighted by these findings. The main objectives going forward should be to enhance the processes involved in producing anything and to find novel chemical combinations that may accelerate the effective and environmentally benign conversion of energy. By addressing these problems, nanostructured catalysts have the potential to greatly progress renewable energy technology and lessen environmental impact worldwide.
