摘要：A polarizing beam splitter （PBS） design based on a fused-silica lamellar subwavelength transmission grating is demonstrated with the modal method, where TE- and TM-polarized waves are mainly diffracted in the -1st and 0th orders, respectively. The physical explanation of the grating diffraction is illustrated by the interference of the corresponding parts of the two propagating modes, which is very similar to a Mach-Zehnder interferometer. It is shown that diffraction efficients over 99% for a TM-polarized wave in the -1st order and 90% for a TE-polarized wave in the 0th order are obtained at the wavelength of 1.053 μm. The polarization transmission extinction ratios are better than 33 dB and 51 dB for the order 0th and the -1st order, respectively. The splitting properties of the PBS grating designed by the modal method are in good agreement with the results simulated by the rigorous coupled wave analysis method.

摘要：阳极尿素氧化反应(UOR)不仅可以取代析氧反应(OER)降低能耗,还可与析氢反应(HER)协同作用,同时产生氢燃料并净化富含尿素废水.然而,如何高效实现全电解尿素仍然面临挑战.本文首先将铑单原子催化剂(SAC)锚定到镍钒层状双氢氧化物(LDH)表面,以获得多功能电催化剂即Rh/NiV-LDH.该催化剂可以实现低能耗全电解尿素产氢目标.Rh/NiV-LDH在100 mV过电位下具有较高HER质量活性(0.262 A mg^(-1))和转化频率(TOF:2.125 s^(-1))此外,Rh/NiV-LDH表现出优异的UOR催化活性,仅需要1.33 V电压即可达到10 mA cm^(-2)的电流密度,表明UOR具备克服缓慢OER动力学缓慢的潜力.实验数据和理论计算证明,Rh/NiV-LDH出色的催化活性归因于NiV-LDH载体和单原子Rh位点的协同作用.将自支撑Rh/NiV-LDH分别作为尿素全电解池的阴极和阳极(1.0 mol L^(-1)KOH+0.33 mol L^(-1)尿素作为电解液),只需要1.47 V的低电压就可以提供100 mA cm^(-2)的电流密度且具有良好稳定性.这项工作从单原子精确调控的角度对全电解多功能SAC的设计具有重要指导意义.
