研究领域

我们课题组的主要研究方向是高效能量转换的无机纳米功能材料, 围绕无机纳米功能材料的控制制备及其在光-电-化学能相互转换中的应用探索开展工作,重点发展它们在电化学催化、电池储能和水的光电裂解等前沿领域的应用。通过改变纳米功能材料的结构、尺度、形貌,修饰它们的表面,我们可以可控地影响在材料界面发生的电子传递和化学反应速率,从而提高纳米材料在能源转化、储存和利用过程中效率,实现普通材料所达不到的功效。我们的研究涉及到众多交叉学科,如无机材料化学、分析电化学、光电化学和表面化学。通过各种丰富的表征手段, 我们着力于在分子层面上对化学和物理现象的阐释,同时也十分注重研究成果在解决现实问题中的价值。 到目前为止,以第一作者或共同第一作者在Science, Nature Nanotechnology, Nature Materials, Nature Communications, Advanced Materials, Nano Letters 和Journal of the American Chemical Society等一些国际期刊上发表论文约30余篇。论文总引用次数3000多次,其中2篇超过500次,10篇超过100次。 电化学催化 电化学催化反应是实现电能和化学能相互转换的主要途径之一。我们课题组着重研究的电化学反应包括电化学析氧、析氢、氧还原、醇氧化等等。这些反应发生在很多重要的能源转换过程中如燃料电池、金属-空气电池、水的裂解等。传统最有效的电化学催化剂常基于贵金属元素,如Pt、Pd、Ru、Ir。它们稀有的储量和昂贵的价格是制约它们大规模应用的致命缺陷。寻找高效廉价的催化剂是电催化领域的一个研究热点和重点。我们希望通过对催化材料成分、结构和尺寸的调控,大幅改进它们的催化活性和稳定性,以替代传统的贵金属催化剂。 在前期的工作中,我们发展了一系列无机金属氧化物、硫化物和石墨烯或碳纳米管的复合材料,率先系统地考察了它们的电化学催化性能,发展出若干高催化活性和稳定性、具有巨大实际应用价值的复合型电化学催化剂。
