Graphite/rolled graphene oxide/carbon nanotubes (G/R‐GO/CNTs) was prepared and applied as a photoanode for water splitting from exhaust car solution. R‐GO was prepared from graphene oxide (GO) using the modified Hummer method after settle down in solution for 2 months to roll out. The R‐GO coated the graphite (G) electrode using the dip‐coating method to form G/R‐GO. Finally, CNTs were prepared on the G/R‐GO electrode by using the chemical vapor deposition method to form G/R‐GO/CNT electrode. The images of field emission scanning electron microscope show the formation of relatively homogenous and uniform R‐GO with an average diameter of about 140 nm. Also, the high density of CNTs was observed with uniform diameters distribution and lengths of CNTs up to several micrometers. The values of the current density of G/R‐GO/CNT electrode for water splitting are changed from 0.82 mA cm−2 in dark to 1.50 mA cm−2 in light. The value of incident photon‐to‐current efficiency was 8.4% at 470 nm. The thermodynamic parameters were calculated, in which the activation energy (Ea), enthalpy (ΔH*), and entropy (ΔS*) values were 8.1 kJ mol−1, 29.9 J mol−1, and 56.4 J K−1 mol−1, respectively.

石墨/轧制氧化石墨烯/碳纳米管光电极用于汽车废液的水分解
制备了石墨/轧制氧化石墨烯/碳纳米管（G / R-GO / CNT）并用作从阳极溶液中分解水的光阳极。R-GO是用改良的Hummer方法由氧化石墨烯（GO）制备的，然后在溶液中沉降2个月以进行铺展。R-GO使用浸涂法涂覆石墨（G）电极以形成G / R-GO。最后，通过化学气相沉积法在G / R-GO电极上制备CNT，以形成G / R-GO / CNT电极。场发射扫描电子显微镜的图像显示平均直径约为140 nm的相对均匀均匀的R‐GO的形成。另外，观察到高密度的CNT，其具有均匀的直径分布和直至几微米的长度的CNT。-2在黑暗中1.50毫安厘米-2中的光。470 nm处入射光子-电流效率的值为8.4％。的热力学参数计算，其中所述活化能（Ë一个），焓（Δ ħ *），和熵（Δ小号*）的值分别为8.1千焦耳摩尔-1，29.9Ĵ摩尔-1，和56.4Ĵķ -1摩尔-1。
