Professor Chun-Yi Chen's research lab specializes in the design and application of advanced nanostructured materials for sustainable energy conversion and environmental remediation. The lab focuses on developing innovative yolk@shell and hollow nanostructures—particularly those incorporating plasmonic and semiconducting components—for efficient solar-driven water splitting, with an emphasis on photocatalytic, electrocatalytic, and photoelectrochemical processes. A key research direction involves structural engineering of nanomaterials to optimize light absorption, charge separation, and surface reactivity. The lab also investigates the propagation of optical pulses in atmospheric turbulence, contributing to the advancement of free-space optical communication systems.

With the escalating demand for clean and sustainable energy sources, hydrogen emerges as a paramount contender, necessitating efficient and innovative production methods of water splitting. This review ventures into the burgeoning field of yolk@shell nanostructures and their pivotal role in advancing water splitting technologies. The synthesis, unique properties, and multifaceted applications of yolk@shell nanostructures across electrocatalytic (EC), photocatalytic (PC), and photoelectrocatalyti
Abstract Structural engineering has proven effective in tailoring the photocatalytic properties of semiconductor nanostructures. In this work, a sophisticated double‐hollow yolk@shell nanostructure composed of a plasmonic, mobile, hollow Au nanosphere (HGN) yolk and a permeable, hollow CdS shell is proposed to achieve remarkable solar hydrogen production. The shell thickness of HGN@CdS is finely adjusted from 7.7, 18.4 to 24.5 nm to investigate its influence on the photocatalytic performance. Co
General formulations of the temporal averaged pulse intensity for optical pulses propagating through either non-Kolmogorov or Kolmogorov turbulence are deduced under the strong fluctuation conditions and the narrow-band assumption. Based on these formulations, an analytical formula for the turbulence-induced temporal half-width of spherical-wave Gaussian (SWG) pulses is derived, and the single-point, two-frequency mutual coherence function (MCF) of collimated Gaussian-beam waves in atmospheric t
