报告题目1：Energy‑Saving Catalyst Strategies for Water Splitting

报告人简介:Dr. Wenxian Li is an ARC Future Fellow at UNSW Sydney, recognised for his pioneering work in materials chemistry and sustainable energy technologies. His research focuses on chemical recycling and upcycling of waste plastics, catalytic reaction kinetics in confined environments, and advanced nanocomposites for energy applications. Dr. Li has secured over AU$40 million in competitive research funding and leads projects supported by the Australian Research Council, ARENA, and industry partners. As an active contributor to the global research community, Dr. Li serves on the editorial boards of Journal of Advanced Ceramics. He has delivered keynote and invited talks at major international conferences and chaired Energy Oceania 2024.

Dr. Li’s research spans sustainable materials and clean energy technologies. He develops catalytic systems for chemical recycling and upcycling of plastics, aiming to close the loop on polymer waste. His work explores reaction kinetics in micro- and nano-environments to enhance catalytic efficiency. Additionally, he designs functional-unit-based hierarchical nanocomposites for energy storage and conversion, including hydrogen generation and advanced batteries. His interdisciplinary approach integrates materials chemistry, nanotechnology, and green engineering to address global challenges in energy sustainability and environmental protection.

报告内容简介:Catalysts are essential in water electrolysis in helping split water into hydrogen and oxygen by lowering the energy needed for those reactions. Improving these catalysts involves careful choices in materials, designing their microstructure, and leveraging engineering techniques. Yet, energy losses in electrolysis are often underestimated because several factors interact: catalyst structure and dimensions, interactions among catalyst, electrolyte, and gas, surface chemistry, electron flow through electrodes, and charge transfer between components. To meet the growing demand for green hydrogen—especially under industrial, high current density conditions—we must evolve catalysts beyond their intrinsic activity and shape them into electrodes that function efficiently at scale. This seminar focuses on strategies to enhance the intrinsic catalytic activity, mass transport, improve charge transfer, and reduce overall electrode resistance—all aimed at cutting energy consumption in water electrolysis.

报告题目2：高亮度蓝光钙钛矿发光二极管的高通量构筑与集成

报告人简介：程露，安徽工业大学讲师。近年来，主持完成国家自然科学基金项目1项、安徽省自然科学基金项目1项；在Nature Communications、Advanced Materials等期刊参与发表学术论文4篇；获授权国家发明专利1项、软件著作权1项。

报告内容简介：金属卤化物钙钛矿半导体因其优异的光电性能、低廉的材料成本以及简易的加工工艺，在信息显示领域展现出广阔的应用前景。近年来，钙钛矿基发光二极管在外量子效率、色纯度和色域等关键性能指标上已逐步满足商业化需求，然而在蓝光器件亮度提升、多色LED集成及高通量可控制备等方面仍面临诸多挑战。三维混合卤素钙钛矿结构具有载流子迁移率高、光谱易调控等优势，更有利于实现高亮度蓝光发射，但其固有的卤素偏析与快速结晶特性限制了蓝光器件性能的进一步提升。本研究揭示，上述问题主要源于原子尺度上铅八面体中卤素分布的不均匀性，并据此提出卤素分布均一化策略，成功实现了高亮度蓝光钙钛矿LED。此外，物理气相沉积作为OLED规模化制备的主流工艺，近年来在钙钛矿LED领域亦有所尝试，但多采用多源共沉积方式，存在工艺控制难度大、与传统溶液法兼容性差等问题。本报告提出一种溶液法与气相沉积顺序结合的复合工艺，在三维混合卤素钙钛矿蓝光体系中取得初步成功，并进一步拓展至红光与绿光体系，初步验证了该路径在大面积、高通量可控制备方面的可行性与应用潜力。
