Imaging the footprint of nanoscale electrochemical reactions for assessing synergistic hydrogen evolution

Dataset complementary to supporting information, such as optical movies, and Python codes to analyze the data according to the manuscript submitted for publication.<br> The movies correspond to cyclic voltammetry operando monitoring by optical microscopy of the reduction of water + KCl in the presence of NiCl2 at an ITO electrode or NiCl2 or MgCl2 at ITO electrode coated with Pt nanoparticles.本数据集为已投稿学术论文手稿的配套补充材料，包含光学录像以及用于按照该手稿要求对实验数据进行分析的Python代码。 上述录像对应通过光学显微镜开展循环伏安法操作中原位监测的两类反应：其一为氧化铟锡（Indium Tin Oxide, ITO）电极上，氯化镍（NiCl₂）存在时水与氯化钾（KCl）混合体系的还原反应；其二为负载铂纳米颗粒的氧化铟锡电极上，氯化镍（NiCl₂）或氯化镁（MgCl₂）的还原反应。
