光谱电化学研究光谱变化作为施加的电势或电流的函数。虽然没有标准的实验设置，但透明电极最通常用于透射模式。在反射模式下工作会迫使光穿过样品两次，从而导致更高的灵敏度，但反过来需要使用高反射电极。在这里，我们提出了由不同的锑锡氧化物（ATO）导电颗粒制成的丝网印刷电极的生产和表征。所得电极显示出优异的光谱电化学性能，例如反射率比传统石墨丝网印刷电极高20倍，但具有可比的电子转移速率。这些电极代表了传统材料的有吸引力的替代品，并拓宽了一般电化学和光谱电化学特别是合适的电极材料的选择。
Spectroelectrochemistry studies spectral changes as a function of applied potential or current. While there is no standard experimental setup, transparent electrodes are most typically used in transmission mode. Working in reflection mode forces light across the sample twice, resulting in higher sensitivities, but in turn requires the use of highly reflective electrodes. Here we present the production and characterization of screen-printed electrodes made from different antimony tin oxide (ATO) conducting particles. The resulting electrodes display excellent spectroelectrochemical properties, such as reflectivities up to 20 times higher than conventional graphite screen-printed electrodes, but with comparable electron transfer rates. These electrodes represent an attractive alternative to conventional materials and widen the choice of suitable electrode materials for electrochemistry in general and spectroelectrochemistry in particular.
