Electrochemical oxygen reduced reaction(ORR)is a critical element in clean energy *** efforts to enhance gas transfer to the reaction interface,the low solubility of O_(2)molecules and slow diffusion rate in liquid electrolyte is still a significant ***,we design an artificial outer membrane on microalgal cells,which consists of a carbon dots/bilirubin oxidase(CDs/BOD)ORR catalyst layer and a L-cystine/Au nanoporous O_(2)supply layer.O_(2)generated by photosynthesis from microalgal cells then can be directly transported to the CDs/BOD catalytic interfaces,overcoming the sluggish gas transfer in the ***,the cathode constructed by the fabricated microalgal cells realizes an ORR current density of 655.2μA/cm^(2) with fast ORR kinetics,which is 2.68 times higher than that of a BOD cathode fed with pure O_(2).A membrane-less glucose/O_(2)biofuel cell is further developed using the hybrid artificial cells as the cathode,and the power density is 2.39 times higher than that of a BOD cathode biofuel cell in O_(2)saturated *** biomimetic design supplies O_(2)directly to the carbon dots/BOD catalyst layer from the microalgae membrane through a nanoporous L-cys/Au layer,providing an alternative solution for the transfer barrier of O_(2)in the electrolyte.

Hydrogenase is a paradigm of highly efficient biocatalyst for H_(2) production and utilization evolved in nature. A dilemma is that despite the high activity and efficiency expected for hydrogenases as promising catalysts for the hydrogen economy, the poor oxygen tolerance and low yield of hydrogenases largely hinder their practical application. In these years, the enigmas surrounding hydrogenases regarding their structures, oxygen tolerance, mechanisms for catalysis, redox intermediates, and proton-coupled electron transfer schemes have been gradually elucidated;the schemes, which can well couple hydrogenases with other highly efficient(in)organic and biological catalysts to build novel reactors and drive valuable reactions, make it possible for hydrogenases to find their niches. To see how scientists put efforts to tackle this issue and design novel reactors in the fields where hydrogenases play crucial roles, in this review,recent advances were summarized, including different strategies for protecting enzyme molecules from oxygen, enzyme-based assembling systems for H_(2) evolution in the photoelectronic catalysis, enzymatic biofuel cells for H_(2) utilization and storage and the efficient electricity-hydrogen-carbohydrate cycle for high-purity hydrogen and biofuel automobiles. Limitations and future perspectives of hydrogenasebased applications in H_(2) production and utilization with great impact are discussed. In addition, this review also provides a new perspective on the use of biohydrogen in healthcare beyond energy.

Developing flexible bioelectronics is essential to the realization of artificial intelligence devices and biomedical applications, such as wearables, but their potential is limited by sustainable energy supply. An enzymatic biofuel cell(BFC) is promising for power supply, but its use is limited by the challenges of incorporating multiple enzymes and rigid platforms. This paper shows the first example of screen-printable nanocomposite inks engineered for a single-enzyme-based energy-harvesting device and a self-powered biosensor driven by glucose on bioanode and biocathode. The anode ink is modified with naphthoquinone and multiwalled carbon nanotubes(MWCNTs), whereas the cathode ink is modified with Prussian blue/MWCNT hybrid before immobilizing with glucose oxidase. The flexible bioanode and the biocathode consume glucose. This BFC yields an open circuit voltage of 0.45 V and a maximum power density of 266 μW cm-2. The wearable device coupled with a wireless portable system can convert chemical energy into electric energy and detect glucose in artificial sweat. The self-powered sensor can detect glucose concentrations up to 10 mM. Common interfering substances,including lactate, uric acid, ascorbic acid, and creatinine, have no effect on this self-powered biosensor. Additionally, the device can endure multiple mechanical deformations. New advances in ink development and flexible platforms enable a wide range of applications, including on-body electronics, self-sustainable applications, and smart fabrics.

Anthraquinone Derivative Chiral Schiff Base Copper（Ⅱ） Complexes for Enzyme Type Bio-Fuel Cell Mediators

Journal of Electrical Engineering 2016年第4期4卷 189-195页

作者： Yuto Takeuchi Takashiro Akitsu Department of Chemistry Faculty of Science Tokyo University of Science Tokyo 162-8601 Japan

Electrochemically, laccase, a family of multi-copper oxidase, has specificity for performing not only one-electron oxidation of phenolic-related compounds but also four-electron reduction of oxygen, which is expected to be a cathode of biofuel ceils. We have prepared three amino-acid derivatives （for enhancing affinity to laccase） and one control （just for determining redox behavior of ligands and Cu（II/I）） copper（lI） complexes 0-3 having phenolic-related ligands involving anthraquinone moiety. Enhancing current density of electron transfer between the cathode （composed of electron conducting materials such as Nation and carbon nanotube） and laccase could be observed for all 1-3 acting as good mediators according to （spectro）electrochemical results.

关键词： biofuel cells oxygen reduction Schiffbase Cu(II) complex anthraquinone.
