项目摘要
Our project hypothesis is that extremely energetic microwave-driven convection and heating are possible for both inlaid-disk nanoelectrodes and nanoparticles immersed in solution and that massive improvements in electroanalytical processes can be achieved with these microwave effects. These phenomena (temperature, mass transport) can be directly measured and quantified in electrochemical experiments employing nanoelectrodes. At very small electrodes turbulence can be suppressed and unusually fast convective flow can be achieved (driven by microwave induced thermal gradients) giving high currents and beneficial effects e.g. kinetic resolution in analytical applications (sulphide, thiol, arsenite, oxygen, carbon dioxide, etc.). More importantly, the adsorption of microwaves into the double layer of interfaces with sufficiently fast RC time constant (e.g. at nanoelectrodes) has never been reported and may again lead to novel chemical phenomena (e.g. for processes involving H2, CO2, or CO adsorbates on Pt, Pd, or Au). These kinds of processes (which occur only at nanoelectrodes or nanoparticles) could be important for sensor and fuel cell processes.
我们的项目假设是,非常高能的微波驱动的对流和加热是可能的嵌入盘纳米电极和纳米粒子浸泡在溶液中,并在电分析过程中的大规模改进,可以实现这些微波效应。这些现象(温度,质量传输)可以直接测量和量化的电化学实验采用纳米电极。在非常小的电极处,湍流可以被抑制,并且可以实现异常快速的对流流动(由微波诱导的热梯度驱动),从而提供高电流和有益效果,例如在分析应用(硫化物、硫醇、亚砷酸盐、氧气、二氧化碳等)中的动力学分辨率。更重要的是,微波以足够快的RC时间常数(例如,在纳米电极处)吸附到双层界面中从未被报道过,并且可能再次导致新的化学现象(例如,对于涉及Pt、Pd或Au上的H2、CO2或CO吸附物的过程)。这类过程(仅发生在纳米电极或纳米颗粒上)对于传感器和燃料电池过程可能很重要。
