What is Data Extraction in Catalysis?
Data extraction in the context of
catalysis refers to the process of collecting and organizing data from various experiments, simulations, and literature to better understand catalytic mechanisms and improve catalyst design. This can involve a wide range of data types, including kinetic measurements, spectroscopic data, computational results, and more.
Why is Data Extraction Important?
Data extraction is crucial because it allows researchers to build comprehensive datasets that can be used to uncover trends, develop predictive models, and validate theoretical predictions. Properly extracted and curated data can accelerate the discovery of new catalysts and optimize existing ones, leading to advancements in fields like
green chemistry, energy production, and pharmaceuticals.
Common Sources of Data
