Fig. 6 Scheme illustration of the transformation mechanism from h-NH 4 x WO 3- y to o-WO 3 #cod#x000b7;13H 2 O f and corresponding TEM proofs a-e. Panels b and d are the enlarged images of a and c, respectively, and they clearly reveal the undergoing oriented attachment process between primary rods. This process has also been schematically illustrated in the framed regions of red circles in a and c
