Abstract

Hydrogen production by water splitting is one of the most effective technologies for supporting the transition to clean energy, as it can produce green hydrogen with low carbon emissions. The performance of this process is influenced by the characteristics of the electrocatalytic materials used as electrodes. Therefore, the development of materials with high electrocatalytic activity, good stability, and optimal charge transfer efficiency remains a key focus of research. A literature review methodology involving the analysis  and investigate of various scientific publications on the development of semiconductor- and metal oxide-based electrocatalysts, including BiVO₄, TiO₂, CuO/ZnO, and NiFe₂O₄, for hydrogen production via water splitting. A variety of research indicate that each material exhibits distinct mechanisms for performance enhancement, such as visible light absorption capability, chemical stability, the formation of p/n-type heterojunctions, and redox mechanisms within spinel structures. In morphological engineering strategies, the formation of heterostructures, optimization of electronic structures, and interface engineering can increase current density, reduce overpotential, and accelerate charge transfer in the Hydrogen Evolution Reaction (HER) and Oxygen Evolution Reaction (OER). The integration of various material engineering strategies represents a promising approach in the development of efficient, stable, and sustainable electrocatalysts to support future green hydrogen production.

Abstract

Although groundwater is the primary source of clean water for most Indonesians, its quality is often compromised by physical and chemical parameters that exceed safe limits, such as high turbidity, a pungent odor, and excessive concentrations of iron (Fe) and manganese (Mn). This study focused on testing the effectiveness of groundwater purification using activated carbon filter media in a Fiber Reinforced Plastic (FRP) tube filtration system. This study evaluates filtration performance in accordance with the Environmental Health Quality Standards (SBMKL) for sanitation and hygiene purposes, as stipulated in Regulation of the Minister of Health (Permenkes) of the Republic of Indonesia No. 2 of 2023. The experimental results show that the activated carbon filter operates efficiently; it is capable of reducing turbidity by up to 85%, significantly eliminating odors, lowering iron (Fe) levels to meet the quality standards of Permenkes No. 2 of 2023, and reducing the concentrations of manganese (Mn), nitrate, nitrite, and Cr⁶⁺ which were already within the standard range from the outset. Thus, the effluent analysis confirms that the treated water meets regulatory standards and is suitable for daily sanitation needs.
