Professor Dai’s research work spans from polymer and carbon nanomaterials design and synthesis to device applications for real-world impact. His group’s multidisciplinary research activities cover the following areas:
Green and renewable energy technologies, such as fuel cells, water splitting, metal-CO2 batteries, hold great promise to solve the world’s energy and environmental challenges. However, to achieve this, high-cost noble-metal-based catalysts are required. Various carbon nanomaterials have shown potential as catalysts for applications in energy due to their:
Good electrical conductivity
High tunability of structures at the atomic/morphological level
Free from metal dissolution and poisoning
To address this, our team develops the design principles, novel precision synthesis, and in-situ operando characterization methods to understand, control and direct the catalytic activities of carbon-based metal-free electrocatalysts for key electrochemical reactions involved in energy conversion and storage.
We develop synthetic methods for the preparation of nanomaterials with well-defined structures. Our focus is on the synthesis and functionalization of vertically-aligned carbon nanotubes (VACNT), VACNT-graphene 3D hierarchical architectures and size-/shape-controlled graphene sheets and nanodiamonds for various applications, ranging from multifunctional nanocomposites to energy-/bio-related devices.
We synthesise conjugated macromolecules of well-controlled optoelectronic properties for light-emitting diodes, field-effect transistors, batteries, supercapacitors, photovoltaic cells, and chemical/biological sensors. Functional nanomaterials, including carbon nanotubes, quantum dots, and DNA thin films, are used as the photon/electron/hole mediators. We also use a combined experimental and theoretical approach to understand and optimize the materials structure and device performance.
To ascertain the potential hazards of nanomaterials to humans (particularly in bio-related systems), we investigate the surface and size effects on the cytotoxicity and genotoxicity of nanomaterials with and without surface functionalization. Our findings are used to guide the design and develop functional nanomaterial for bio-related applications, including multifunctional biosensing, controlled drug delivery, photodynamic therapy, and catalytic medicine. We also undertake bioinspired approaches for designing and synthesizing materials with functional structures and smart features (e.g. DNA-directed self-assembling, Gecko-foot-mimetic dry adhesion).
