Controlled Synthesis and Photocatalytical/Electrochemical Research of Transition Metal Sulfide and C3N4 Composites [PDF]
, 2016 化学掺杂（复合）和微观形貌调控是改变材料结构特征，进而改善材料性能的两种主要手段。其中化学掺杂可以改变材料本身的价带和导带的位置，调整能带结构，并且掺杂的原子或复合的半导体化合物会与原材料产生一系列的互相激发反应，在材料表面或内部引起新的化学或物理反应，从而影响物质的性质；而微观形貌调控则是直接针对材料表面，控制合成不同的表面形貌，使其暴露出的活性位点发生改变，从而改变材料表面所带的基团及其比表面积，最终影响材料的光学、热学、电学、力学或化学特性。 在化学掺杂研究中 ...
