Abstract
Water splitting is a sustainable method of hydrogen production that is crucial for achieving carbon neutrality. However, the high cost of green hydrogen remains a major challenge. One strategy to reduce costs is the use of non-precious metal catalysts, such as Co, which is known for its excellent catalytic properties......

https://doi.org/10.3365/KJMM.2023.61.4.284
Abstract
Solar energy is attracting much attention as an eco-friendly source for future energy needs. Herein, NiZnS photocatalysts were synthesized with a hydrothermal method at various sulfur contents. The ZnS material is widely used as a photocatalyst because of its high stability, low toxicity, and excellent charge separation characteristics. Nickel is.....

DOI:
https://doi.org/10.3365/KJMM.2023.61.3.190
Abstract
Green hydrogen has attracted significant attention as one of the future energy sources because no greenhouse gases are emitted during production and its energy density is much higher than fossil fuels. Precious metals such as platinum (Pt) and iridium (Ir)-based catalysts are commonly used for water splitting catalysts. However, because.....

DOI:
https://doi.org/10.3365/KJMM.2020.58.12.907
Abstract
Solar water splitting is an attractive method for producing hydrogen from renewable natural resources, and heterostructure photocatalysts have been widely investigated for photocatalytic applications. Hetero-component photocatalysts can reduce the charge recombination process by improving electron utilization, and are considered promising candidates for solar water splitting. Amongst various heterostructure systems, combinations.....
