Enhancing photoelectrochemical CO2 reduction with silicon photonic crystals
The effectiveness of silicon (Si) and silicon-based materials in catalyzing photoelectrochemistry (PEC) CO2 reduction is limited by poor visible light absorption.In this study, we prepared two-dimensional (2D) silicon-based photonic crystals (SiPCs) with circular dielectric pillars arranged in a SLR square array to amplify the absorption of light w
