无金属光催化在绿色能源应用中引起了广泛的研究兴趣。本论文采用低温等离子体增强化学气相沉积(PE-CVD)技术，在导电衬底上垂直排列二维碳掺杂氮化硼(C-BN)纳米片，研究了其在太阳光照射下对水氧化的光电催化性能。由于这种几何结构，独特的2D材料为催化反应提供了有利条件。此外，调节碳浓度可以很容易地控制C-BN纳米片的结构和光电性能，从而提高太阳光谱的光捕获率。结果表明，与传统的C-BN粉末沉积方法相比，C-BN薄膜的光电流密度提高了60倍。对能带结构进行了实验和理论研究，结果吻合较好。这种基于2D C-BN纳米膜的器件可以激发人们对许多领域的高级应用的兴趣，如催化、传感器、晶体管等。
Metal-free photocatalysis has evoked broad research interest in green energy applications. Herein, two-dimensional (2D) carbon-doped BN (C-BN) nanosheets are vertically aligned on a conductive substrate by low-temperature plasma enhanced chemical vapor deposition (PE-CVD) and are demonstrated to be a photoelectrocatalytic device for water oxidation under sunlight irradiation. By virtue of this geometry, the unique 2D material presents advantages for the catalytic reaction. In addition, adjusting the carbon concentration can facilely control the structure and optoelectronic properties of the C-BN nanosheets to improve light harvesting in the solar spectrum. As a result, the photocurrent density exhibits a 60-fold enhancement over that of the C-BN films achieved by traditional deposition of C-BN powder. Experimental and theoretical studies of band structures are performed and the results are in agreement with each other. This 2D C-BN nanofilm based device could stimulate interest in advanced applications in many fields such as catalysis, sensors, transistors and others.
