Abstract

Crystal facet engineering is a pivotal strategy to design high-performance photoelectrodes and suppress electron and hole complexation, thus enhancing photoelectrochemical (PEC) activity through carrier enrichment at specific crystal facets. However, there is still a lack of systematic resolution on the intrinsic principles of crystal facet tuning energy band structure and the specific adsorption of signaling molecules. In this work, a multidimensional synergistic optimization strategy was proposed to achieve precise prediction and targeted crystal facet design of photoelectrodes by establishing a quantitative structure–activity relationship (QSAR) model of “crystal configuration-molecular recognition-carrier…
