In this review, we provide an overview of recent advances in heterogeneous catalytic deuteration and discuss key catalyst design principles that enable efficient site-selective deuteration and perdeuteration. Particular attention is given to the roles of metal active centers, catalyst supports, substrate properties, and reaction conditions, as well as the growing use of deuterium oxide (D₂O) as a practical deuterium source. We further highlight recent progress in catalyst development and outline future opportunities for sustainable and industrially relevant deuteration processes.

Key Insights

• Metal active centers, catalyst supports, substrate characteristics, and reaction conditions are identified as the four primary factors governing heterogeneous deuteration performance.
• Noble-metal catalysts, including Ir-, Rh-, Pd-, Ru-, and Pt-based systems, continue to demonstrate superior activity and selectivity for hydrogen-deuterium exchange and C-H bond activation.
• Single-atom catalysts have emerged as an effective strategy for maximizing metal utilization efficiency while enhancing catalytic performance compared with conventional nanoparticle catalysts.
• Non-noble-metal catalysts, including Fe-, Mn-, Ni-, and Cu-based systems, are gaining increasing attention as cost-effective and sustainable alternatives capable of achieving high deuterium incorporation.
• Deuterium oxide (D₂O) is becoming an increasingly attractive deuterium source because of its low cost, wide availability, and compatibility with heterogeneous catalytic processes.
• Metal-free deuteration methods, particularly electrochemical and photochemical approaches, offer promising routes for deuterium incorporation under mild reaction conditions without the risk of metal contamination.
• Rational catalyst-support engineering can regulate electronic structures, adsorption behavior, and hydrogen spillover effects, leading to improved catalytic efficiency and isotope selectivity.
• Significant advances have been achieved in perdeuteration, where both monometallic and bimetallic catalyst systems provide high deuterium incorporation while minimizing undesirable side reactions.
• Continuous-flow deuteration technologies are progressing rapidly and offer advantages in safety, process control, scalability, and industrial implementation.
• The integration of advanced characterization techniques, mechanistic investigations, computational modeling, and machine-learning-assisted catalyst design is accelerating catalyst discovery and deepening understanding of deuteration mechanisms.

Why This Matters

Deuterium-labeled compounds play important roles in pharmaceutical development, mechanistic studies, analytical chemistry, and materials science. Advances in heterogeneous catalytic deuteration have transformed the field into a versatile platform for efficient isotope incorporation. The development of highly active catalyst systems, especially those capable of utilizing inexpensive D₂O, has significantly improved the practicality, sustainability, and scalability of deuteration processes. Continued progress in catalyst design and process engineering is expected to support broader applications in drug discovery, isotope labeling, and industrial chemical production.

Looking Ahead

Future research opportunities include:

• Developing ultra-low-loading noble-metal catalysts with enhanced atom efficiency.
• Expanding the capabilities of non-noble-metal catalytic systems.
• Improving deuteration processes that rely on inexpensive D₂O.
• Advancing mechanistic understanding through in situ characterization and theoretical studies.
• Applying machine learning and computational screening to catalyst discovery.
• Accelerating the adoption of continuous-flow manufacturing for large-scale deuterated compound production.

These directions are expected to contribute to more efficient, sustainable, and industrially viable deuteration technologies in the coming years.
