碳 包覆 或 掺杂?这得看你要的碳是起什么作用了。如果做energy storage方面的话,不用太高温度和碳的结晶度,用小分子(单糖多糖等等)碳化成无定形的碳就可以。eg. Adv. Mater. 2011, 23, 2076–2081.??黄新堂还有在ZnO上包层炭的,也是用葡萄糖溶液,用的500℃,炭层大概6 nm的样子。We chose 500 °C as the carbonization temperature because at this temperature the generated carbon could be partially graphitizd to benefit the LIB performance and the deleterious interfacial reaction between ZnO and Ni foil could also be avoided.如果要追求rate performance或催化方面的,最好就是导电性好的聚合物。PANI or PEI等。eg.
