AI-Enabled Holistic Framework
This research introduces a holistic framework that integrates advanced machine learning into traditional catalyst design. It combines knowledge-based insights, derived from domain expertise and literature, with powerful data-driven techniques. The core components include:
- Open-access electronic structure databases: Providing precise physicochemical descriptors for materials.
- Pre-trained natural language processing (NLP)-based embedding models (mat2vec): Generating higher-level abstractions that capture generalized physicochemical processes from vast scientific literature.
- Physical-driven predictive models: Trained on over 700 high-quality experimental results to bridge scientific hypotheses with tangible experimental outcomes, ensuring feasibility at the design stage.
This framework efficiently screened 54 candidate catalysts, identifying three with exceptional potential for achieving high-purity semiconducting CNT arrays, demonstrating a significant leap in design efficiency.
Selective CNT Growth Mechanism
A novel method for selective semiconducting CNT synthesis is proposed, centered around catalyst-mediated electron injection, precisely tuned by light during growth. The underlying hypothesis is that promoting electron transfer from catalysts to CNTs preferentially enhances the growth of semiconducting CNTs by significantly reducing their formation energy, while the high conductivity of metallic CNTs hinders electron localization.
High-throughput experiments rigorously validated these predictions, with semiconducting selectivity consistently exceeding 91% across optimized catalysts. Notably, the FeTiO3 catalyst achieved an impressive 98.6% selectivity, demonstrating the framework's ability to optimize complex systems. This selective growth is achieved through a controlled charge transfer facilitated by light, offering a powerful new pathway for targeted nanomaterial synthesis.
Generalizable Methodology
Beyond the specific application of semiconducting CNT synthesis, the AI-enabled holistic design approach offers a generalizable methodology for global catalyst design and the synthesis of diverse nanomaterials. The framework's ability to integrate disparate data types (electronic structures, textual embeddings, experimental results) and learn complex relationships positions it as a powerful tool for:
- Addressing multifaceted challenges: Optimizing multiple physical and chemical phenomena simultaneously.
- Advancing materials science: Providing a robust platform for precise control over material properties and performance optimization.
- Accelerating discovery: Significantly improving research efficiency compared to traditional trial-and-error methods.
This paradigm holds immense promise for propelling in-depth development across various nanomaterial synthesis scenarios, offering a blueprint for future scientific discovery.

Case Study: FeTiO3 Catalyst Performance
The AI-enabled framework successfully identified FeTiO3 as a top-performing catalyst, demonstrating its predictive power in complex nanomaterial synthesis. Through a process of systematic screening and optimization, FeTiO3 achieved an impressive 98.6% semiconducting selectivity for carbon nanotube growth under light-assisted conditions (Fig. 3d).
This outstanding performance validates the hypothesis of catalyst-mediated electron injection enhancing s-CNT growth. The catalyst was prepared via a sol-gel method and calcination, with its morphology showing uniformly distributed nanoparticles (Fig. 3b). Detailed characterization, including XPS (Supplementary Fig. 7b) and KPFM (Fig. 4g-j), confirmed its composition and the electron transfer mechanism under illumination, cementing FeTiO3 as a prime example of AI-driven material discovery.
