Chapter 9: High Throughput Experimentation for the Discovery of Water Splitting Materials

High throughput experimentation is a powerful approach for accelerating materials discovery, particularly when embedded within a larger research effort providing clear guidance as to technologically relevant device operating conditions and in which discovered materials can be rapidly validated, further investigated, and incorporated into devices. In this chapter we provide an overview of high throughput pipelines developed to discover solar fuels materials, with particular attention given to electrocatalysts and photoelectrocatalysts for the oxygen evolution reaction. The description of the pipelines details our philosophy that experiment throughput must be contingent on establishing high data quality, which is embodied by our strategic choices of synthesis, screening, characterization, and data management techniques. This account of high throughput discovery of solar fuels materials provides a template for designing high throughput pipelines for mission-driven science research.
