Synthesis of BNiO3 Nanocomposites for Photocatalytic Hydrogen Production Applications

Abstract

The pursuit of sustainable and clean energy sources has prompted significant research efforts toward developing efficient photocatalytic materials for hydrogen production. In this study, we present a comprehensive review of the synthesis of BNiO<inf>3</inf> nanocomposites and their potential application as efficient photocatalysts for hydrogen production. The synthesis of BNiO<inf>3</inf> nanocomposites involves the integration of bismuth oxide (Bi<inf>2</inf>O<inf>3</inf>) and nickel oxide nanoparticles with boron nitride nanosheets. Various synthesis techniques have been employed to fabricate these nanocomposites, including sol–gel, hydrothermal, and co-precipitation methods. The choice of synthesis method significantly influences the nanocomposites' structural, morphological, and optical properties, thereby affecting their photocatalytic performance. The morphological characterization techniques, such as scanning electron microscopy, transmission electron microscopy, and X-ray diffraction, have been utilized to investigate the structural and morphological properties of BNiO<inf>3</inf> nanocomposites. The photocatalytic activity of BNiO<inf>3</inf> nanocomposites for hydrogen production has been extensively studied. The mechanism of hydrogen production involves the absorption of solar energy by the BNiO<inf>3</inf> nanocomposites, followed by the generation of electron–hole pairs. This report provides valuable insights into the synthesis techniques, characterization methods, and photocatalytic performance of BNiO<inf>3</inf> nanocomposites. Further research is warranted to optimize the synthesis parameters and explore novel strategies for enhancing the efficiency and stability of these nanocomposites, ultimately contributing to the development of sustainable energy solutions. © The Institution of Engineers (India) 2024.
