内容摘要:
In the drive for cleaner energy solutions, the efficiency of catalysts and optoelectronic devices hinges onunderstanding and controlling nanoscale variability. Traditional characterization methods average materiaproperties, obscuring subtle yet critical heterogeneities that dictate performance. This presentation outlines amicroscopy-centered strategy to elucidate how nanoscale structural and functional diferences impact the behavioof solid catalysts and metal-halide perovskites-two material classes central to sustainable energy conversion ancstorageBv leveraging advanced optical and electron microscopy technigues, including fluorescence microscopy andRaman spectroscopy, our approach captures transient, localized phenomena that traditional methods miss. Forthin films hasexample,our high-resolution imaging of strained black CsPblealed thermalnon-equilibrium statesthat are directly linked to phase stability and charge dynamicstherebyinforming strategies forimproving perovskitesolar cells and photocatalysts. Similarly, single-turnover fluorescence microscopy has enabled spatially resolvedobservation of crystal-face-dependent catalytic activity, establishing that even minute variations at the nanoscale cardramatically influence overall catalytic efficiency. Together, these investigations demonstrate that advancecmicroscopy is not merely a tool for observation, but a catalyst for innovation. By directly correlating structure withfunction at the nanoscale, we can accelerate the development of materials that deliver enhanced efficiency, stability.and selectivity-critical parameters for next-generation energy technologies.
