We present a new approach for the preparation of electrocatalytically active carbonaceous coatings embedding bimetallic nanoparticles (NPs) - AgPt@C structures, on surfaces with 2D and 3D geometry such as glass covered with indium tin oxide (ITO) film and anodic aluminum oxide substrates, respectively. We provide extensive characterization of the deposited structures and demonstrate their performance towards the electrocatalytic glucose oxidation, one half-reaction of biofuel cells. We observe that a preliminary surface treatment of the porous alumina substrate is essential for a homogeneous laser-induced deposition of AgPt@C nanoparticles across the whole pore depth.

我们提出了一种制备具有双金属纳米颗粒（NPs）-AgPt @ C结构的电催化活性碳质涂层的新方法，该结构在具有2D和3D几何形状的表面上，例如覆盖有氧化铟锡（ITO）膜的玻璃和阳极氧化铝基底，分别。我们提供了沉积结构的广泛表征，并展示了其对电催化葡萄糖氧化（生物燃料电池的一半反应）的性能。我们观察到多孔氧化铝基材的初步表面处理对于整个孔深度上均匀激光诱导的AgPt @ C纳米粒子的激光沉积至关重要。
