ÎÄÏ×Ô­ÎÄ£ºThese  freshly cleaned ITO glasses were used to deposit a thin layer of TiO 2 of thickness ∼ 30 nm by immersing the substrate in a solution
containing 0.1 M (NH 4 ) 2 TiF 6 and 0.2 M H 3 BO 3 for 30 min at
25 ¡ã C. The substrates were then spin coated by 0.60 mol L
- 1
of Zn(CH 3 COO) 2 ¡¤ 2H 2 O in a 2-methoxyethanol/monoethano-
lamine to form ∼ 50 nm thick seed layer of ZnO, followed by
heat  treatment  at  300 ¡ã C  for  10  min  to  obtain  dense  and
transparent seed layers. (2) ZnO template growing. The seeded
substrates were placed in an aqueous solution containing 0.015
M
Zn(NO 3 ) 2 and 0.015 M hexamethylenetetramine at 95 ¡ã C
for 2 h. Subsequently, the resultant films were thoroughly rinsed
with deionized water (DI) to remove any residual salt or amino
complex and dried with compressed air. (3) TiO 2 nanotube
forming. The synthesized ZnO nanorod arrays on ITO were
immersed in aqueous solution consisting of 0.075 M (NH 4 ) 2 TiF 6
and 0.2 M H 3 BO 3 at room temperature for 1.5 h. The resulting
TiO 2 nanotubes were then dipped in a 0.5 M H 3 BO 3 solution
for 1 h to remove any residual ZnO.

mol/L

Although the preferred unit for concentration is mol dm-3, because 1 dm3 is equal to 1 litre (L), concentration may also be quoted as mol/L, mol/dm3, mol L-1, or even just ¡®M¡¯. 2 M sulfuric acid is therefore sulfuric acid with a concentration of 2 moles per litre. International convention however recommends that this use of ¡®M¡¯, and the use of the term ¡®molarity¡¯ instead of concentration, be discontinued as M is the notation commonly used for molar mass.
