1TiO_(2) Nanocrystals Grown on Graphene as Advanced Photocatalytic Hybrid Materials显示文摘A graphene/TiO_(2) nanocrystals hybrid has been successfully prepared by directly growing TiO_(2) nanocrystals on graphene oxide(GO)sheets.The direct growth of the nanocrystals on GO sheets was achieved by a two-step method,in which TiO_(2) was first coated on GO sheets by hydrolysis and crystallized into anatase nanocrystals by hydrothermal treatment in the second step.Slow hydrolysis induced by the use of EtOH/H2O mixed solvent and addition of H2SO4 facilitates the selective growth of TiO_(2) on GO and suppresses growth of free TiO_(2) in solution.The method offers easy access to the GO/TiO_(2) nanocrystals hybrid with a uniform coating and strong interactions between TiO_(2) and the underlying GO sheets.The strong coupling gives advanced hybrid materials with various applications including photocatalysis.The prepared graphene/TiO_(2) nanocrystals hybrid has superior photocatalytic activity to other TiO_(2) materials in the degradation of rhodamine B,showing an impressive three-fold photocatalytic enhancement over P25.It is expected that the hybrid material could also be promising for various other applications including lithium ion batteries,where strong electrical coupling to TiO_(2) nanoparticles is essential.Yongye Liang Hailiang Wang Hernan Sanchez Casalongue Zhuo Chen Hongjie Dai 2010Nano Research2010,3,10:57
2Advanced Asymmetrical Supercapacitors Based on Graphene Hybrid Materials显示文摘Supercapacitors 在水的答案操作是有能力的高骑车稳定性并且快收费并且排出的低费用精力存储设备,但是通常受不了低精力密度。这里,我们种 Ni (哦) 高质量的 graphene 表上的 2 nanoplates 和 RuO2 nanoparticles 以便最大化这些材料的特定的电容。我们然后在 Ni 上面配对(哦) 有一个 RuO2/graphene 电极到的 2/graphene 电极负担得起高效有在 1.5 V 的电压在水的答案操作的高精力和功率密度的不均匀的 supercapacitor。不均匀的 supercapacitor 基于 RuO2 碳或 Ni 比对称的 RuO2-RuO2 supercapacitors 或不均匀的 supercapacitors 展出显著地更高的精力密度(哦)2 碳电极对。48 W 甠瑬慲散瑮楲畦慧楴湯的高精力密度?Hailiang Wang Yongye Liang Tissaphern Mirfakhrai Zhuo Chen Hernan Sanchez Casalongue Hongjie Dai 2011Nano Research2011,4,8:37
