Perovskite Structures for Thermochemical Hydrogen Production with Performance Metrics

Hydrogen production values ranging from 4.51 to 16.33 cm3STP/gmaterial·cycle were measured for La0.8Me0.2NiO3±δ perovskite macrostructures. The dataset, created by Pérez Domínguez, Alejandro and harvested from e-cienciaDatos, contains results from experiments on materials shaped into pellets, reticulated porous ceramics, and thin films. It was last updated on October 14, 2025.

Use Cases

• Comparing hydrogen production performance based on different perovskite dopants (Al, Ba, Ca) and reduction temperatures.
• Analyzing the effect of material shaping strategies (powder vs. pellets vs. thin films) on gas-solid contact and heat transfer efficiency.
• Modeling the relationship between thermal reduction temperature (800-1200 °C) and redox performance for solar reactor integration.

Strengths

• Reports specific hydrogen production values, such as 14.91–16.33 cm3STP/gmaterial·cycle for the best-performing thin-film structure.
• Evaluates materials under defined thermal reduction temperature ranges from 800 to 1200 °C.
• Compares multiple material configurations: powdered perovskites, pellets, reticulated porous ceramics, and thin films.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
