• Smart Catalyst Design: Integrating Structure–Activity Relationships with Computational and Data-Driven Approaches (2026) · International Journal of Creative and Open Research in Engineering and Management · doi

  The development of more efficient, selective, and durable catalytic systems is necessary to address energy security, climate change, and sustainability. The current state of catalyst design has limitations, such as the difficulty in obtaining high metallic loadings. The use of single-atom catalysts and metal-organic frameworks can improve catalytic activity.
