In this work, Au NPs decorated porous hollow tubular carbon materials (PHTCs@Au) by direct carbonization of zeolitic imidazolate framework-8 (ZIF-8) derived from ZnO nanorods were prepared and used as enzyme immobilizing matrix to construct a bioanode for glucose/O-2 biofuel cells (BFCs). Due to high surface area, good electric conductivity and extraordinary porous-hollow tubular structure of PHTCs@Au, the resulted enzyme electrode (PHTCs@Au/GOD (glucose oxidase)-GA (glutaraldehyde)/glassy carbon (GC) electrode) exhibited excellent catalytic capacity towards glucose oxidation and good stability. For the assembled glucose/O-2 BFC with the PHTCs@Au/GOD-GA/GC electrode as the bioanode and a commercial Pt plate electrode as the cathode, the maximum power density of 310 mu W cm(-2) can be obtained at 0:23 V, and the open circuit potential is 0.63 V. The attractive features of PHTCs also provide potential applications in energy storage and conversion devices such as supercapacitor and fuel cells, etc.
