电化学水氧化是太阳能转换工作的主要焦点。开发了一种新的实验室实验，利用实时，动手研究来发现太阳能转换的催化剂。HARPOON或用于氧超电位中和的快速过氧化的异质阳极实验允许并行分析混合金属氧化物组合物的阵列以测试它们作为水氧化催化剂的活性。学生创建混合金属氧化物材料的独特组合，然后利用一个简单，廉价的系统进行分析，该系统检测电解过程中产生的氧气量。这一实验具有灵活性，可以在不同的教育水平上实施，相应地涵盖了材料的深度和广度。可以强调化学计量，材料，溶液和荧光等概念，而研究式的体验可以加强学生的独立性，批判性思维能力和对科学的兴奋。
Electrochemical water oxidation is a major focus of solar energy conversion efforts. A new laboratory experiment has been developed that utilizes real-time, hands-on research to discover catalysts for solar energy conversion. The HARPOON, or Heterogeneous Anodes Rapidly Perused for Oxygen Overpotential Neutralization, experiment allows an array of mixed-metal oxide compositions to be analyzed in parallel to test their activity as water oxidation catalysts. Students create unique combinations of mixed-metal oxide materials, which are then analyzed utilizing a simple, inexpensive system that detects the amount of oxygen evolved during electrolysis. This experiment has the flexibility to be implemented at a variety of educational levels with the depth and breadth of the material covered accordingly. Concepts such as stoichiometry, materials, solutions, and fluorescence can be emphasized, while the research-like experience strengthens students’ independence, critical-thinking skills, and excitement for scienc...
