Sustainable energy generation from water splitting using trimetallic layered-double hydroxide and graphitic carbon nitride nanocomposite

“

The reliance on fossil fuels for energy generation has led to significant environmental degradation, primarily due to carbon dioxide emissions. The extensive use of these fuels poses severe risks to human health and the environment, contributing to global warming and air pollution. Consequently, the pursuit of carbon-free energy sources has become increasingly critical, with hydrogen production through water splitting emerging as a viable renewable alternative. However, for hydrogen to be a practical energy solution, it must be produced efficiently and cost-effectively compared to traditional fuels. Current challenges include the high costs and limited availability of noble metal catalysts, prompting funding from donor agencies to explore more affordable alternatives. While transition metal-based catalysts show promise, their efficiency remains insufficient to compete with existing energy technologies. To tackle this challenge, a range of strategies are implemented, including the development of composite catalysts that leverage synergistic effects, morphological modifications, the application of layered double hydroxides, cocatalysts, and the incorporation of highly conductive materials like graphitic carbon nitride to enhance efficiency.
