  摘要：

  The preparation, surface attachment, optical, and photoelectrochemical properties of metal cyanide complexes, cis-[(4,4'-(CO2H)(2)bpy)(2)M(CN)(2)] where M = Ru(II) and Os(II), attached to sol-gel processed TiO2 electrodes are reported. The specific sol-gel process provides a route to stable, high surface area anatase TiO2 films. With surface anchored [(4,4'-(CO2H)(2)bpy)(2)Ru(CN)(2)] we report incident-photon-to-current efficiencies exceeding 90%. The net photocurrent scales linearly over 5 decades of incident irradiance. The molecular level similarity of the two polypyridyl complexes allows for a meaningful comparison of the electrooptical properties of Ru(II) and Os(II) derivatized surfaces. A kinetic interpretation with different sacrificial electron donors provides insight into the rate limiting step(s) in the photosensitization process. An increased rate of electron tunneling from the semiconductor conduction band to the oxidized dye and a more sluggish halide oxidation rate are believed to be responsible for a low photocurrent efficiency observed with surface-anchored [(4,4'-(CO2H)2bpy)(2)Os(CN)(2)]. The results and interpretation suggest methods for developing more efficient photovoltaic devices.

  of enzyme molecules, fewer than 1% participate in the desired reaction. In contrast, when the electrostatic adduct of polyanionic enzyme and a water soluble electron-conducting redox polymer are crosslinked on an electrode to form a film that swells in water, most of the enzyme molecules electrocatalyze the reaction. The reason is that electrons are exchanged between the enzyme’s reaction centers and

  我们报告了在 37.5oC、pH 5 柠檬酸盐缓冲液中以 5 mA cm 的电流密度和 +0.7 V (NHE) 将氧四电子电催化还原为水的情况。在接近中性 pH 值和环境温度下将 O2 电还原为水一直是电化学中历史最悠久、研究最深入的问题之一。它一直是微型无膜生物燃料电池的一个缺失元件，其预计各自的面积和体积功率密度分别为 1 μW mm 和 10 μW μL。与一次锂电池不同，这种电池在阳极电氧化葡萄糖，在阴极电还原溶解的 O2，可以将其小型化到亚毫米尺寸，因为它不需要难以小型化的外壳或密封件。该电池的应用是为基于芯片的传感器和发射器供电，在人体内运行一周并传输到约 1 m 的距离。这样的系统只需要几百 nW 的功率，其燃料电池将仅包括电催化阳极和阴极条，每条约 1 毫米长，沉积在芯片上。这种新型电催化剂由亲水性碳布制成，该碳布涂有来自 Coriolus hirsutus 的漆酶（pH

  Oxygen was electrocatalytically reduced to water at a current density of 5 mA/cm(2) and at +0.7 V (NHE) in pH 5 citrate buffer at 37.5 degreesC. The electrocatalyst was a composite of laccase cross-linked with a redox. polymer on a hydrophilic cloth of 10 Aim diameter carbon fibers. The redox polymer, PVI-Os(tpy)(dme-bpy)(2+/3+), [poly-N-vinyl imidazole with 1/5(th) of the imidazoles complexed with [Os(tpy)(dme-bpy)]2+/3+ (tpy=terpyridine; dme-bpy= 4,4'-dimethyl-2,2'-bipyridine)], electrically connected ("wired") the laccase reaction centers to the fibers.
