Abstract:
The solar energy-driven photoelectrochemical (PEC) water splitting and artificial photosynthesis have been continuing to drive substantial developments in new materials and methods for optimizing the energy conversion and utilization efficiency. Meanwhile, these studies have been inspiring research efforts in utilizing the PEC conversion platform to investigate the chemical/biological targets in life sciences. Here, we would like to present our recent works in designing and fabrication of semiconductor nano-heterostructures that are capable of being tailored during synthesis for enhanced solar energy-driven PEC energy conversion and utilization, including efficient photoabsorption, charge separation, and charge transfer. In addition, attributed to their suitable band alignment and excellent photoactivity, these nanowire-based structures are capable of post surface functionalization for molecular recognition and PEC catalysis, leading to solar energy-driven, real-time, sensitive detection of a variety of biologically important molecules for cellular signaling and enzymatic functions. Moreover, the chemical stability and biological benignity of these nanowire arrays further enable direct interfacing with primary neuron networks and in-situ photoelectrochemical neuron stimulation for artificial retinas. These hybrid nanowire photoelectrodes suggest new structures with enhanced photoactivity and sensitivity, which may allow for new exciting studies of interfacing of nanomaterials and biomaterials.
