GO was prepared by a modified Hummer’s method.45–48 To wrap GO onto the surface of the bare LLNCM particles, a modified methodology based on ref. was applied. Firstly, 0.3 g of the asprepared LLNCM was immersed into 30 mL polyallylamine hydrochloride (PAH) solution (1 g L-1) with continuous stirring for 1 h, followed by separation using a centrifuge and washing 3 times, after which the powders were immersed in 15 mL GO aqueous solution (2 g L-1), and stirred for another 5 h. The LLNCM coated with GO was washed and then immersed into L-ascorbic acid (LAA) aqueous solution at 95 C for 30 min with continuous stirring. Finally, the powder was dried at 80 C overnight, and the resulting powder was designated as LLNCM/GO. The as-prepared LLNCM/GO powders were heat treated at either 250 C (designated as LLNCM/G-250), or 350 C (designated as LLNCM/G-350), for 2 h in air. To study the influence of LAA on LLNCM, the bare LLNCM was also treated with LAA (LLNCM/LAA), followed by heat treatment at 350 C for 2 h (LLNCM/LAA-350). 希望能帮到你，我也在做氧化石墨烯的还原 |
