Special Issue Information

Dear Colleagues,

Over the years, the issue of carbon dioxide (CO2) emissions and their impact on climate change has become increasingly urgent. In response to this global challenge, researchers have been exploring innovative solutions for capturing and converting CO2. Among these, nanomaterials have emerged as promising candidates due to their unique properties and versatile applications in CO2 capture, storage, and conversion processes. This Special Issue aims to highlight the latest advancements in the field of nanomaterials for CO2 capture and conversion and their potential contributions to addressing climate change.

This Special Issue of Nanomaterials aims to provide a platform for sharing cutting-edge research and advancements in nanomaterial utilization for CO2 capture and conversion. We welcome contributions across various topics, including but not limited to the following:

  • Synthesis and characterization of novel nanomaterials for CO2 capture and conversion;
  • Mechanistic studies and theoretical modeling of CO2 adsorption and conversion processes on nanomaterials;
  • Development of advanced nanocomposites and hybrid materials for enhanced CO2 capture efficiency and selectivity;
  • Applications of nanomaterials in catalytic CO2 conversion reactions, such as electrocatalysis, photocatalysis, and thermal catalysis;
  • Integration of nanomaterial-based technologies into practical CO2 capture and utilization systems.

Submissions can encompass experimental and theoretical perspectives, along with interdisciplinary approaches that merge materials science, chemistry, engineering, and environmental science. Through this collaborative effort, we aim to advance our understanding and utilization of nanomaterials for CO2 capture and conversion, contributing to a more sustainable and greener future.

Bismuth Vanadate (BiVO4) is a promising photoanode material due to its stability and suitable bandgap, making it effective for visible light absorption. However, its photoelectrocatalytic efficiency is often limited by the poor transport dynamics of photogenerated carriers. Recent research found that varying the atomic arrangement in crystals and Fermi levels across different crystal orientations can lead to significant differences in carrier mobility, charge recombination rates, and overall performance. In this work, we optimized the atomic arrangement by controlling the crystal growth direction to improve carrier separation efficiency using a wet chemical method. Systematic investigations revealed that the preferential [010]-oriented BiVO4 film exhibits the highest carrier mobility and photocurrent density. Under an applied bias of 1.21 V (vs. RHE) in a 0.5 M Na2SO4 electrolyte, it achieved a photocurrent density of 0.2 mA cm−2 under AM 1.5 G illumination, significantly higher than that of the [121]-oriented (0.056 mA cm−2) and randomly oriented films (0.11 mA cm−2). This study provides a deeper understanding of the role of crystal orientation in enhancing photoelectrocatalytic efficiency. Full article
