This problem-based case study presents recent advancements in the development and application of technologies geared towards harnessing sunlight for the production of hydrogen from water. A PowerPoint presentation introduces the topic with a New York Times excerpt about a growing market of fuel cell-powered toys. Might similar technologies also address our transportation needs? Students next read a general overview from Chemical & Engineering News about the challenges associated with developing robust and economically feasible water-splitting catalysts and the recent development of a low-cost heterogeneous cobalt phosphate catalyst. Students also read a primary literature article from Science on the cobalt phosphate catalyst and then complete a three-page worksheet (included in the teaching notes) as a collaborative learning activity designed to increase understanding of the basic electrochemical principles underlying hydrogen production. This case study was originally written for a second semester/third quarter general chemistry course and presented after the units on thermodynamics and electrochemistry have been covered.
